Article: How to Monitor your SharePoint Environment

As SharePoint becomes a more critical component of your infrastructure, it also becomes a service that needs to be more closely monitored to ensure its availability. But many organizations mistakenly try to treat SharePoint like other application servers, such as SQL Server. The reality is that SharePoint can be incredibly more complicated.

The most common misconception is that it's SharePoint that you have to monitor. This false belief will lead most operations personnel to overlook the fact that SharePoint is really a combination of services that act together. Because these services are tightly integrated, your monitoring strategy needs to be multidimensional.

For more information, read “How to Monitor your SharePoint Environment” on SearchWinIT.

Updated ECM vendor evaluations available today from CMS Watch

CMS Watch has released their updated ECM vendor evaluations. One of the key findings is that nearly all of the ECM vendors sell a SharePoint connector, leading to coexistence with MOSS instead of competition.  Another interesting finding is that ECM vendors are finally starting to focus on mobile computing.

If you’re in the market for an ECM package or need to better understand the capabilities of a tool you already own, I would recommend reading this report.

Social Networking on Intranets (Jakob Nielsen's Alertbox)

A friend and taxonomy expert, Stephanie Lemieux (Earley and Associates) passed along a link to Social Networking on Intranets, on Jakob Nielsen's Alertbox.  The article reinforced recommendations we typically make to our clients.  And although the title suggests the article is strictly about social media, it was also an excellent list of how to be successful in intranet development generally. 

If you don’t have the time for the full article, here’s a summary:

  1. Employees use social media in their private lives and have come to expect the those same tools to be available inside the organization.  As Nielsen states “[s]ocial software is not a trend that can be ignored. It's affecting fundamental change in how people expect to communicate, both with each other and the companies they do business with.”  Some organizations we’re working with fear that the words “social software” will prevent executive buy in.  If that’s true, change the words, but don’t ignore the advice. 
  2. In fact, Nielsen goes on to say that most executives don’t generally support social media because they themselves don’t use these tools personally.  However, organizations “don't have to teach or convince younger workers to use these tools; they expect them and integrate them as easily into their work lives as they do in their personal lives.”
  3. Tools don’t matter – it’s the problems the tools solve.  Consejo is often called to help organizations implement SharePoint.  In many cases, these enterprises don’t have a good sense of how SharePoint will help solve business challenges; they simply own SharePoint licenses and now want to use them. Nielsen suggests that “organizations are successful with social media and collaboration technologies only when the tools are designed to solve an identified business need.”  In other words, the “build it and they will come” approach to SharePoint deployment won’t work unless there’s a clear business benefit and employees can easily identify how SharePoint helps them to realize that benefit.
  4. One surprise finding was that Nielsen recommends integrating new tools into the intranet without fanfare and let employees discovery the functionality naturally.  Advertising new tools as “new” won’t help spur adoption and that some terms (used to describe tools or features) may be scary – Nielsen uses RSS and social bookmarking as examples of “scary” terms.
  5. Support both content contributor and content consumer communities within your intranet.  Nielsen states that “[a]s with the open Internet, there's substantial participation inequality in enterprise communities: some employees participate a lot, while others mainly lurk… value a community based on a combination of posting and use...”  As I mentioned in my previous post on SharePoint governance, successful intranets must create vibrant content contributor and consumer communities (filed under Poole’s Rules regarding giving encouragement and show appreciation).  Further, as a part of measuring success, you should count both types of participation equally.
  6. Search is only as good as the content it indexes.  Truer words have not been spoken.  Many organizations lament about poor search quality.  Unfortunately, those same enterprises fail to take the necessary steps to improve results.   As Nielsen states “[t]raditional methods for relevancy scoring on the Web don't work as well on the smaller scale of most intranets: for example, counting links works only if you're doing so across a huge base of links. But, even if only a few employees tag a page with a given keyword, it's likely that the page will produce a good search result for that query in your organization's context.”  In a recent “Making Basic SharePoint Search Work” (a free Jumpstart call with Earley and Associates), I discussed how to improve SharePoint search results using out-of-the-box techniques for tagging.
  7. Nielsen found that “it’s essential to provide a single, unified search across all intranet resources.”  Many search products, including SharePoint, can search across many different kinds of source repositories.  Critical to search success is finding the most relevant content, regardless of its location.  Playing on the theme in Nielsen’s article, enterprises should include social media and collaborative spaces in search results, even if the content is not completely “final” or authoritative.
  8. “Content-is-King 2.0”  The tool is nothing without content to consume.  This finding supports actively encouraging content contributors during an initial roll-out and ensuring there’s ongoing content authoring.  As Nielsen states, “[a]n empty wiki can be a lonely place and also hard to sell to users.”
  9. Employees should be able to use the intranet will little or no training.  If users have to “figure out” how to use a tool, they’ll tend to avoid it.  Further, you need to ensure the language you use is familiar.  Nielsen points out that describing something as “Twitter-in-the-enterprise” or “micro-blogging ” will be equally inaccessible to users not familiar with the concept.  One approach, used in our Fast Track to SharePoint, is licensing training materials like SoftwareFx Virtual Training Center for SharePoint 2007.  It can be embedded in your intranet, accessible at any time.  The training is provided as 100 modules that are 30 seconds to 4 minute videos delivered through a flash video player.   Users are shown the features in action instead of just being told.
  10. Open communication is a requirement.  Nielsen suggests that communication groups need to adapt to the speed at which employee communications need to be developed: “Corporate communications must adapt to social media’s real-time culture and become more proactive than in the past… procedures that required days or weeks for approval need dramatic streamlining…”  It may be unnerving to executives to have an open discussion of company policies on the intranet, but it may mitigate the risk that the same employees will use more public internet services.  However, Nielsen cautions, there is still a place for “official” communications and that the two must co-exist.

REVIEW: Samsung Jack and Windows Mobile 6.1

I recently replaced my 1st generation Samsung BlackJack with the latest generation Samsung Jack.   I had spent months agonizing over what new mobile phone to buy (partly because of equipment and partly because I wanted to wait for the oft-delayed Windows Mobile 7).  I looked at the obvious non-Windows contenders like the Apple iPhone, the RIM Blackberry Bold, as well as other Windows Mobile smart phones, but still came back to the Jack.

In the end, I chose the Jack for a few reasons, listed in order of importance below:

  1. I really wanted to stay with the Windows Mobile platform.  Windows mobile is often maligned for poor performance and even worse battery life.  However, I’ve had pretty good luck with both my Audiovox SMT5600 and Samsung BlackJack.  Both phones worked quite well and I’m usually near a computer, giving me access to trickle charges when necessary.  I’ve not suffered any of the performance problems and I’m tied to an Exchange e-mail account; synchronizing between a Windows smart phone and Exchange is mostly flawless.
  2. Despite some issues with dropped calls and terrible customer support, I wanted to stay with AT&T.  I’ve used both Verizon and Sprint in the past, but found AT&T to be an equal carrier for the locations I visit.  As for custom service, issues and frustrations seem to be universal.  That said, Verizon certainly has much better coverage in less densely populated areas, but I am usually in a medium to large city.  Even when I’ve made it into “the country,” I’ve not had any challenges with AT&T.  Finally, AT&T has international coverage (although expensive), which I’ve used a number of times without incident.  Besides T-Mobile (whom I didn’t consider at all), none of the other U.S.-based mobile carriers handles roaming internationally (at least not well).
  3. After looking at all of the Windows mobile equipment options with AT&T, it came down to the Samsung Epix and the Jack.   Most of my elimination criteria centered on talk time (very important), size (important) and price (important).  The two phones were generally equal when it came to talk time.  The Epix seemed to have the edge on functionality, but was larger than the Jack.  The screen resolution was also higher on the Epix, but I couldn’t get past the relatively small, but noticeable size difference.  Plus, virtually every other aspect of the phones was imperceptibly similar or the same.
  4. AT&T offered a $49 deal to upgrade to the Jack (after a $100 rebate that I have yet to mail in).  I was not able to get an equal deal on the Epix

I’ve been using my new Jack (which looks hauntingly like a Blackberry Bold) for about a month.  In that time I’ve made the following observations:

  • The phone is light, slim and unobtrusive.  It’s slightly shorter than my old BlackJack, but the slick plastic housing is a bit more of a challenge to grip compared with the matte, rubberized finish on the BlackJack.  However, it fits nicely in my pocket without the bulk associated with larger phones.
  • Battery life and management seem to be quite a bit better than my old BlackJack and SMT6500.   I can typically go two days, with moderate usage, without recharging the battery.  My other phones would barely last a day or less before complaining of low power.
  • Windows Mobile 6.1, which is what the Jack shipped with, is much improved over Mobile 5.  I really like the “Slide” interface and haven’t had the any issues with lockups or glitches. 
  • Overall, there just seems to be more intelligence in the design to both the phone and operating system.  I particularly like the single touch button for many functions like mail (which the BlackJack had) and the camera.
  • I really dislike the GPS and AT&T buttons.  The GPS button is tied to the AT&T Telenav application/service.  It’s an extra charge to use the service on AT&T’s network and I’m just as happy to use Bing Mobile or Google Maps Mobile; both work well, though I think I’m more favorable to Bing Mobile at the moment after some very positive early experiences, though neither have audible driving directions.  As for the AT&T button, it seems like a hold over from Cingular and it navigates me to a 404 page; not a fabulous experience.
  • When the keyboard is locked, Mobile 6 has the same faulty behavior that Mobile 2003 had in that it will allow you to dismiss a meeting reminder, but not “snooze.”  Mobile 5 had corrected this oversight, but I think Microsoft forgot to add that functionality back to Mobile 6… weird.
  • I really like that you can now invite others to meetings you schedule with your phone.  That was functionality previously missing from the Windows Mobile platform.
  • Mobile 5 had the ability to send a picture or video shot with the phone through a pre-defined mail account.  This functionality worked flawlessly on my old BlackJack.  However, it fails to work on my new Jack.  When I’ve tried to send a phone or a video, the phone reports that I don’t have any e-mail accounts setup (except that my phone has been synchronizing and sending e-mail through Exchange since day 1).  I thought I may have missed some setting somewhere, but I can’t find it.   I’m hoping the problem is easy to fix, but I haven’t spent enough time investigating.
  • The phone could do with more onboard memory.  It came with only about 2/3rds of the onboard space available.  After installing apps like Bing and Google Maps, I’m closer to half full.  Also, my phone was filled with a bunch of junk I can’t seem to uninstall (like demo games that want money to play).  I could care less about the spamware AT&T installed on the phone, but I could really use that space back.  Unfortunately, none of these games (or the other silly things AT&T insists on adding to my phone – like links to web sites that don’t exist) are listed in the Remove Software option on the phone. 
  • The keyboard is laid out differently than my BlackJack and is a little smaller.  The layout and size seem similar to the BlackBerry.  I’ve generally gotten the hang of it, but I still find myself hitting the space bar instead of the 0 (zero) button when dialing numbers; previously the zero and space were the same key.

In the end, I like the phone (I withhold a modifier like “really” until I have more time with the device).  I think it was an excellent upgrade from my BlackJack and if you’re looking for an upgrade to your Windows Mobile phone, I would recommend it.

Make SharePoint Governance Plain and Simple

Much has been written on the topic of SharePoint governance (and just to satisfy the Bing lovers: SharePoint governance).  Microsoft even has a Governance Resource Center for SharePoint on their TechNet site.  While most of the content I’ve found is quite good, though a bit fragmented, I still felt like there was something missing.

In fact, all of the discussions around governance got me thinking about the idea that you should be able to create a model where governance just “happened.”  Before you go away thinking that I’ve spent a bit too much time inhaling paint fumes, hear me out:  is it possible  to create a self sustaining “culture” of governance where participants reinforce content and technology best practices because “that’s the way we do business?”  I think the answer is: YES.

Recently, I’ve had the opportunity to work with a number of older companies – companies for whom computing technology is relatively new compared with their years in business.  Many of these older companies, especially those with a strong founder affinity, have a deeply engrained company culture.  This culture is so pervasive that it permeates virtually everything they do without being overbearing.  

I’m not speaking of the largely manufactured “culture” we saw sprout during the dot com days; that’s the kind of culture that never leaves any lasting impression beyond a few hollow words by an executive.  I’m speaking of , the real ingrained and consuming kind of culture.    Examples can be found in companies like GE, Caterpillar, Kiewit and the “old” IBM (somewhat paradoxically specifically because they’re a technology company).  These companies have a “way of doing business” and new employees quickly learn this “way” by having it reinforced by the processes and people around them.

Another such culturally rich company is PCL Constructors Inc.  They’re based in Edmonton, Alberta, Canada.  PCL’s founder, Ernest Poole, created a memo that’s now called “Pooles Rules.”  At the time of its creation, it created the basis for a company culture, PCL’s business practices and values.  Even today, the words of Mr. Poole are displayed throughout their headquarters and guide the companies business practices. 

What struck me about the rules was the plain and simple language used to describe “how to do business.”  These rules can be applied to a broad set of circumstances, even ones that couldn’t have been anticipated by Poole himself.  Today, while the language may seem “old,” the concepts and guidelines haven’t gone out of style and PCLers still largely operate using the insight that Mr. Poole jotted down on a single piece of company letterhead nearly 70 years ago.

To demonstrate just how applicable the rules are, I’ve created a derivative work that could be used as a basis for a SharePoint governance “culture.”  I’ve replaced certain words in Poole’s Rules with more SharePoint or portal-relevant terms (if necessary). 

  • Employ highest grade employees obtainable
    SharePoint is a unique product with it’s own complexities and nuances.  I’ve seen some companies try to “fit” employees into a SharePoint administration role or use less-experienced resources to create solutions.  Just as Mr. Poole suggests using the highest grade employees to build a building, you should strongly consider the same approach for your SharePoint environment.   Frankly this rule is just good business and common sense.
  • Encourage integrity, loyalty and efficiencies
    Create an environment where your content consumers and contributors see the SharePoint solution as central to their work.  This means avoid “snazzy” features for their own sake and instead focus on real time-saving or productivity-improving functions.  These functions don’t have to be complicated and can be simply a good employee directory or the place to find the right template for proposals.  By considering the time your users will invest in learning the new SharePoint solution and leveraging any given function, you’ll avoid overloading them with frivolous content or features – this builds loyalty, trust and a sense that the SharePoint application is meant to improve efficiency, not make it harder to get work done.  Further, employees won’t try to use “rogue” applications to get their work done, since you’ve demonstrated real value.
  • Avoid side lines
    Don’t try to make your SharePoint environment be all things to all people.  As I’ve mentioned in the past, SharePoint has strengths and weaknesses.  Make sure you know what they are and avoid trying to make SharePoint do something it wasn’t meant to handle.  It’s better to do a few thing well than create a broad, mediocre application.
  • Do not permit side lines by employees [or SharePoint environments]
    Don’t allow rogue SharePoint implementations in your environment; more than one organization I’ve worked with suffers this problem.  Multiple, unmanaged SharePoint environments cause lots of pain in the organization and confuse the general employee population.  I would highly recommend working to create a tightly controlled, singular (or set of SharePoint) environment(s) that can be relied on, supported and recovered (in the of a disaster).  The idea is not to create a uber-SharePoint group, but rather apply real discipline to the management of the environment, even if more than one group physically operates an environment.
  • Be fair in all dealings with owners [content contributors and consumers], architects [SharePoint managers], engineers [internal SharePoint developers] and sub-contractors [consultants]
    The critical bit of  the initial deployment as well as long term application management is to understand there are lots of individuals, groups and interests involved.  You will do well to develop very clear goals for your environment, a plan to achieve the goals and metrics to measure success.  In addition, communicate constantly with everyone involved.  How does this equate to fairness?  In the end, no one group can bear the brunt of the development or maintenance.  Your contributors can’t be expected to create content over night, managers can be expected to solve “world hunger,” it should be understood that it will take more than 24 hours to design/develop/test/deploy a SharePoint solution and any consultants you hire don’t know your business as well as you do.  In addition, you need to make the environment accessible and easy to use for your content consumers.  Try to minimize overburdening one group or another when developing and maintaining your solution.
  • Keep your word as good as your bond
    This is about credibility.  If you (as the “owner” of the Intranet) want to encourage use,  make sure you deliver what you promise and what is useful.  This means not only delivering the obvious – SharePoint functions and the environment – but also the ongoing content contribution, continuous improvements and overall management.  Living web applications – whether their internally or externally facing --  need to be cared for and “fed” to survive.  Once you’ve built your solution, you or another group must be responsible for keeping your implied promise that the solution won’t be abandoned.
  • Give encouragement and show appreciation
    I had the good fortune of working for knowledge management guru Susan Hanley while at Dell.  She was famous for saying that organizations should use techniques like “bribery” to create a vibrant community of content consumers and contributors to build up an intranet.  In fact, as she often pointed out, without both communities, a intranet will wither and die away.  Providing encouragement and showing appreciation is especially important for fledgling SharePoint environments; participation and adoption are paramount to success.  It’s also critical for ongoing success; consider your own population and develop a program that continuously provides encouragement and support to all communities involved.
  • Be firm, fair and friendly
    Think outside the box, encourage suggestions and get folks involved.   Improvements or changes can come from all levels in the organization.  Treat all who participate as if they can constructively contribute to the environment.  However, it’s also equally important to set firm ground rules for that participation and refuse some requests if they’re either unreasonable or don’t fit the “model” you and your team have developed for the application.  See the “avoid sidelines” rule.
  • Avoid jobs where design is not good or financing doubtful
    If you don’t have the funding, time, human resources or the budget to effectively create, deploy and maintain a SharePoint solution, don’t start one.  I have seen numerous companies attempt to develop a solution with insufficient resources, thinking “it’s just a simple intranet” or “SharePoint does that out of the box.”  There is nothing simple about an intranet and while SharePoint does provide a lot of out of the box functionality, more enterprises must buy add-ons, build customizations and deal with challenges that are often underappreciated.
  • Good accounting and cash keeping are essential [Develop good metrics for success]
  • Do not let finishing up of jobs or collecting payments lag
    These last two bullets are close enough to lump them together.  In construction, like developing a SharePoint solution, demonstrating success is critical.  How do you demonstrate success?  You have objective measure to compare against.  Whether this means that the new application supports a certain number of users, that it helps to reduce the time it takes to accomplish a task or eliminates work altogether, you have to be able to measure it.  Many organizations say that it’s impossible to measure productivity improvements or more “soft” metrics. I would agree that it’s very difficult in many cases to determine whether process improvements have saved time, for example; often you don’t have a baseline to compare against or it’s difficult to gather ongoing data.  However, even anecdotes can serve as a metric (e.g. here’s an example of how I save time generating a proposal using the new intranet).  Further, stay on top of these measures of success both throughout the initial deployment and the applications lifecycle.  It’s the only real way of figuring out whether all the time, money and effort paid off.

Keep in mind that I’m not necessarily endorsing this specific approach for everyone.  However, I think it’s an interesting model to explore when developing a governance program for a SharePoint environment.  Obviously, a good governance has to include more than just a few rules.  That said, writing this blog entry, for me, has only reinforced that there is an argument for creating a relatively broad set of guidelines that can apply across numerous circumstances.  Many companies fail to realize this and end up creating an inaccessible, overly complex governance policy.  In the end, their policy fails because no one understands it or it is too hard to follow. 

Consider creating your own “Poole’s Rules” for your SharePoint environment.  I suspect you’ll not only gain new insight on a practical governance strategy, but also end up creating something that outlives SharePoint.

Create a Support Program for your SharePoint Environment

A recent article in CIO Magazine provided some great content around the true cost of SharePointSocial software and portals expert, Peter Sejersen from J Boye, has expanded that discussion when he added a quick case study of a DIY SharePoint implementation at the municipality of Aalborg in Denmark.  However, one dimension of SharePoint that has not received a lot of attention is support.

In virtually every engagement we have with clients, the cost of supporting SharePoint comes up.   Clients want to better understand what it takes to “care and feed” for an enterprise SharePoint environment.  If you’re struggling with this same challenge, I’ve included some of the various support dimensions touched lightly in the CIO article and that may help you create your support program:

  • Monitoring
    Do you want to get the most value out of SharePoint?  Make sure you monitor the servers, the applications and ensure up-time.  During your implementation’s early stages, little attention will be paid if it’s unavailable.  Once the site has been around a while, you better ensure it’s running in top form.  Beyond that, you should really know if errors are being generated in the event logs, issues manifesting themselves in the SharePoint logs or if your content databases are getting to large.  This means that you must get serious about monitoring and look at more than just ping responses.  Microsoft has System Center Operations Manager, which provides a good tool for monitoring your environment.  You can also leverage a combination of event log monitors, perfmon or manual checks.  At Consejo, we developed a monitoring agent with Panopta and integrated it into our SharePoint Support offering.   Whatever approach you choose, make sure you have one.
  • Patch Management
    The SharePoint team releases patches with relative frequency.  They are sometimes in the form of a “hot fix” (an update the corrects a “small” feature or function within SharePoint), a roll-up (a collection of these hot fixes) or a service pack (the total collection of hot fixes plus updates not found in any hot fix).  Whatever the form, you need to have a program to apply them regularly, since you don’t necessarily want to update SharePoint the way you update the OS.  While you may have a program for applying fixes to your server and desktop OS, a lot of organizations fail to regularly implement SharePoint-specific fixes – some of which are required for working with certain OS and/or .NET framework patch levels.    The tricky bit about this element of  a support program is the number dependencies created by either custom or commercial add-ons; this means testing ahead of deployment.
  • Reusable Components
    Companies like Telerik and Infragistics have made a good business out of creating new controls or components that fill in functional gaps between what Microsoft provides in the .NET framework and what you may have to create for your application.  In the same way, consider creating an organization specific set of controls, components or SharePoint add-ons that you can reuse across your SharePoint applications.   Examples of this might be a “print Wiki” function that can be used with any wiki in SharePoint or SharePoint site archive function that backs up a SharePoint site before deleting it from a Site Collection.    More granular examples may be components that make it easy for developers to connect to your specific SAP implementation.  While your needs may be different, creating a collection of reusable components will help improve development quality and speed within your organization.
  • End-user Assistance/Help
    A lot of IT organizations tend to take the “build it and they will come” approach to SharePoint.  This approach suggests that IT organizations simply need to make a facility like SharePoint available; from there business users will “figure out” how to be more productive.  Unfortunately, most end users are unable to conceptualize how SharePoint can help them to be more productive as they tend to struggle with the basics like simply uploading documents or using search.  Instead, enterprises should create real training materials that translate SharePoint capabilities into tangible benefits in the context of the business.  This means demonstrating how users can be more productive in real situations using SharePoint to supplement or replace tools they already uses – like Word (just as an example).   When we deliver our Fast Track to SharePoint solution, we provide a license for the SoftwareFx Virtual Training Center for SharePoint (created by PortaLogiks) and embed them in the SharePoint application we create for our clients.   The materials give end users 30 second to 4 minute flash-based narrated videos on everything from uploading a document to a document library to customizing a page with SharePoint Designer.  Along with these materials, we typically recommend clients create application-specific help material that will further supplement the rather generic videos with specific information on their implementation.  In this way, business users don’t have to “imagine” how they can be more efficient -- they’re shown.   This will encourage use and help with adoption.
  • Be Serious about Adoption
    Another frequent topic of conversation is end user adoption.  Adoption describes how you get your business users to utilize the new intranet, extranet or internet site you’ve built on SharePoint.   There are no easy answers to help to spur adoption; each organization will need to create a specific program to fit their end-user community.  However, success of your SharePoint implementation will depend entirely on end user adoption.   If you’re interested in learning more, check out a blog entry by Bianca Wong at Prescient Digital Media on change management strategies to support intranet adoption.

Admittedly, creating your own support program will be specific to your organization.   It also likely you’re doing some related activities already, so adding SharePoint-specific elements to those existing programs should not burdensome.  However, consider the alternative costs if you avoid creating a disaster recovery program or skimp on training your users.

Article: Effective Site Provisioning for SharePoint

One of the criticisms lodged against SharePoint is that you install it one day and the next day you end up with thousands of sites. Each site brings with it potential security risks from improper security settings and massive storage consumption resulting from, among other reasons, content dumping.

Even assuming you don't have either problem, it's always better to have a well managed SharePoint environment than one without appropriate controls on usage. That's where site provisioning comes in.

To be honest, there's no magic formula for managing the site-provisioning process on SharePoint. Different companies will have success with different approaches. But there are some guidelines that enable every organization to both provide flexibility to its end users and ensure an appropriate framework to help manage growth, security and usage.

NOTE: Beyond what’s mentioned in the article, SharePoint Solutions has a good tool for helping to managing the provision process called siteProvisioning Assistant.  The product provides a nice mix of pre-built approval processes and end user ease of use.
