Strategic IT Update: Changing Role of C-Level Executives

The business environment is becoming more complex, unpredictable and constantly changing. In the near future IT will no longer be the way it is today. Business and Technology integration will be a necessity for business to stay competitive. To achieve this, the CFOs role is expected to become increasing important as described in this video. Following is the first Strategic IT Update.

Key Observations - Service Reusability - Does it really work?

From my experience, on SOA projects reuse was mostly accomplished with technical services/ infrastructure services. However, it is the business service reuse that we are struggling with as the Lines of Business (LoB)/ business units feel that their sub-set of the business logic is very unique. The problem is that most of these business services are rendered non-reusable due to the fact that they include both business logic and process sequencing logic into the same code base and it is the later that is unique to the LoB and not the business logic. Also, we have achieved greater degree of reusablitiy in terms of data access and informational services and not so much business function services that are a higher level class of services.

I would like to hear about what your experience has been with regards to service reusablity. Have you been able accomplish this.

Thanks,

Defining and measuring Business Agility

Image
In my previous post on defining Business Agility I had defined it as follows

Business Agility = Business Alignment + IT Flexibility

Business Alignment: Alignment between the various business units
IT Flexibility: Alignment between Business and IT + ability to rapidly deploy new business capability

Business Agility = Business Intuition + IT * (BPM + SOA)

Of course this definition is pretty generic and the next obvious question is how do we measure Business Agility? Typically most business have one primary measurement criteria - company
financial results such as revenue, operations cost, stock price and profits. There are alternate ways for measure business by adopting Six Sigma, Lean, etc. Again this approach is still business focused - and does not help in measuring IT Flexibility (especially as very rarely have I see IT organizations actually adopt Lean, Six Sigma or any such measuring criteria - maybe that will change :) ).

After giving this much thought I came up with this domain model …

Best Practices - SOA Guiding Principles

From my experience, with SOA Retail solutions the following SOA Guiding Principles have served us well. We have applied this "standard" to both internal SOA style business services and when evaluating other packaged products that claim to be "SOA Enabled"!!!
a) business service consumers are decoupled from business service providers.
b) availability of published "service metadata" enables the discovery of the business service.
c) service consumers are agnostic of who (service provider location) and how (service provider technology platform) the function call is being fulfilled.
d) service consumers and service providers that use industry standard protocols and communications models are able to insure loose coupling.
e) service interaction is based upon exchange of canonical modelsPlease provide me with your feedback.

Best Practice: SOA Development Organization

In early 2006 I had documented my views on how the IT development organizations would change by adopting SOA. I had termed it the SOA Development Organization and I still believe that this is the end state for the IT application development organization.
