Because I have had such a good response I am keeping the debate going in the blog.

Today, in part 22, Tony Prestedge, executive director group development and operations at Nationwide gives us his views.
Prestedge is no stranger to large IT projects. He is responsible for Nationwide's £1bn IT transformation project.
This throws up an interesting question. An ambitious corporate strategy necessitates multiple big projects - as is the case with Nationwide - requiring a view of success at a portfolio level. Have we failed if we achieve the greater goal at the expense of individual projects deviating from plan?
The world doesn't stay still. The clarity of the strategic direction is critically important in assessing the success of 'big' projects against the 'big' picture.
Still, the question remains, do some reasons for 'failure' only crop up on big projects? Experience suggests the same factors affect all projects. However, the bigger the project the more likely they are to occur and the mitigation required grows disproportionately.
Big projects take longer so are more likely to experience life's unpredictable events, they involve more people so are harder to align, they touch more systems so are harder to spec and change control, etc. They need a more pessimistic approach to contingency and governance than smaller ones.
For me success or failure is simply about quality of leadership, team capability, partnerships based on trust and an obsessive focus on execution.
Competent people well led towards a simple and singular outcome works everytime."
