Why is This Important?
There are several reasons why this is important:
- Our stakeholders want to know what they’re going to get. Chances are very good your stakeholders will want to know what you’re going to do, how you’re going to do it, how much it will cost, and how long it will take. You will need to provide them with plausible answers to those questions if you hope to have Construction funded.
- Our team should agree on how we’re going to proceed. As a team we should agree on what we’re supposed to be producing and how we’re going to do so. This is particularly important when people are working from different locations or when the team is large and organized into subteams.
- We want to capture key decisions. Early in the lifecycle we often make important promises about the projected business benefits, the payback period, the scope, and even the technologies to be used or supported. We should strive to fulfill the promises that we make, and disciplined teams (and stakeholders for that matter) will track progress against them.
- We want to stay on track. Having a vision in place, particularly one that is sufficiently captured/documented, provides the team with something to check against during Construction. When you allow the requirements to evolve over time, when the design evolves in step, and when your plan similarly evolves it is easy to get off track and start going in a different direction. Throughout Construction the team should ask itself if they’re still heading in the direction they said they would, and if not their either adjust the direction or the vision accordingly.
