You are evaluating an opportunity and all the different components of the opportunity are there.
The customer has a pain, you have the right solution and some technical people understanding the issue working for them. You know you can build the solution in a couple of weeks, that you are competitive in that niche.
You talked to the business buyer, s/he agrees with the solution approach and the business case is strong: with a good ROI and aligned with the investment strategy approved by governance.
Then, why you should not go ahead with this opportunity?
there’s no compelling event.
