OOB vs. SPD vs. WF vs. k2.net

Battle of the acronyms

In late-January, 2007, I presented a technical demo & discussion session at MOSSIG (Microsoft Office System Special Interest Group).  I’d posted an overview of the content @ grumpywookie.com, but thought it would be worth including at devK2.net.


Tonight was my night to do a presentation @ MOSSIG – entitled Workflows in MOSS.   Just thought I’d cover some of the basics of the prezzo/demo – for those who couldn’t make it – and those those wanting a re-cap (there was a LOT of content !)

Firstly, a brief overview of Business Process Management – collaboration, office automation, integration with back-office systems – and then onto MOSS (Microsoft Office Sharepoint Server)

Within Sharepoint 2007, there are a number of ways to introduce Workflow, each with varying levels of detail.

I like to refer to these as the “small”, “medium” and “large” flavours of workflow implementations.

This is the same when considering (1) functionality, (2) complexity and (3) skill-level-required.

Small – Out Of The Box (OOB)

A number of workflows are installed with the MOSS server is setup. This allows a user to have a document in a library (for example) – with an approval workflow with emails sent to different people requesting comments.

The workflows are pre-installed & pre-configured – you just have to “run them”.

Fairly small level of functionality – can’t change how they operate – and small level of complexity (good for users, bad for developers).

BUT – a relatively small level of skill involved – so most non-techy users can jump into some quick workflows.

To MOSS or not to MOSS? Workflow may be the answer. (screen-shots)

Introduction to SharePoint Workflow

Medium – Sharepoint Designer (SPD)

The replacement for FrontPage is more than just a HTML editor, and web page creator. Open a “site” from within SPD, and you can add a workflow that you create from scratch.

This is point and click, with a list of Conditions and Actions. This is fairly detailed in it’s functionality – allowing a developer (or power-user) to have logic steps (if-then), and resultant happenings (update a list item, send an email, move/delete a list item, etc)

Medium level complexity, yet limited to the set list of options. And no ability to debug. And more skills required, but not rocket science.

Large – Windows Workflow Foundation (WF)

Using Visual Studio.NET and 3.0 of the framework, developers can codify almost anything with the custom-written workflow. This allows for many different integration points – such as the ability to call web services (I don’t know if SPD can do so – will check).

Basically watered-down BizTalk – very advanced functionality is possible – but it’s all code-driven – highly complex. And can be tricky to deploy to use within Sharepoint.

A fairly large amount of skill required to drive this one.

Regardless of the workflow “creation”, one thing lacking is a proper workflow “server”.

Sharepoint is handling this all behind the scenes – but you can’t see how workflows are progressing in an easy to understand GUI sense – nor report on workflow average durations, or staff through-puts – and thus refine & “tune” your business processes.

And so – “there’s a gap” – with the need to develop “more custom” workflows than those provided in SPD – but – needs to be easier & more productive than WF within VS.NET.


This a .NET written IDE and server for integrating to/from Sharepoint. With the ability to have GUI based workflow layout & design, K2.NET offers developer ease, while not relinquishing features & flexibility.

A number of templates within the toolbox provide different wizard screens, allowing for easy configuration of decisions & actions – or – you can jump into the code, and modify the auto-generated code – or include your own.

You could (in fact) override the generated code – and write an entire “application” within K2.NET Studio – in VB.NET or C#.

Integration with other systems is thus “EASY” – you would do as within any other .NET code module – or call a web service.

Sharepoint-wise, you can update to/from a document library or list item – as well as have InfoPath forms residing within a document library – and displaying work item details for users to interact with the workflow.

The only downside to K2.NET is the price – it can cost $40,000 or more for a K2 implementation – before any workflows have even been created.

BUT – the time-saving alone – for costly developers – and the ability for business-analyst (tech-savvy) to be involved in design & development of workflows is great.

Another BUT – the integration with MOSS is limited to some extent – not much more that with SPS-2003. Such as the inability to interact with InfoPaths “Forms Server” forms – that’s coming in vNext (code named Black Pearl – just hit Beta).

Even so – well worth a look. Here are some links to find out more about K2.NET :
