The importance of functional gap analysis to project success: A personal experience

I was recently involved in the preliminary stages of a IT project ,at  large organization,  that aimed to replace the central information sharing and document archiving system. The current system was a 10 plus year old mishmash of interdependent modules that were developed in house to meet the needs and demands of various stakeholders. The system no doubt needed to be replaced; the challenging question was what new system would provided the same level of functionality and integration with current business processes.

Despite the obvious challenge in finding an appropriate replacement system, upper management, due to financial pressures and politics, committed themselves to an off the shelf solution designed by an American vendor without conducting a  functional gap analysis in co-ordination with the major stakeholder.  The scope of the system replacement project was therefore limited to; getting major stakeholders to support the proposed change, working with the selected vendor to implement the system and pre-launch training.

The omitted functional gap analysis was a sure recipe for failure. The project planning stage, of which i was part, uncovered several intractable challenges the implementation project will be facing due to the omitted functional gap analysis. The standard answer to each new uncovered challenge quickly became "  well we are already committed to the new system". However, as the project planning progressed and more challenges were uncovered an unspoken consensus slowly emerged; the planned implementation will run into significant problems and the selected system will most likely not meet the needs and demands of its  users. In my estimation, this state of affairs were a direct consequence of the failure to conduct a proper functional gap analysis before selecting the replacement system.

I suspect that the situation I encountered is not uncommon. I imagine that economic pressures or the lure of the latest IT tool or fad, for example cloud computing,  frequently motivates managers to commit similar errors in judgement that ultimately jeopardizes project success.

In the interest of exploring my suspicion further, I will be happy to hear from other members of the class who had had similar project experience.
