In this post, I expand upon Michael Nygard’s post Documenting Architecture Decisions. Michael defines architecturally significant decisions as those decisions that affect the structure, non-functional characteristics, dependencies, interfaces, or construction techniques. I add examples to each of the five decisions categories.
In this post, I cover in a step by step manner how to do software estimation for project bids where there is limited clarity and a lot of ambiguity. I cover how we can use an uncertainty factor to cover the unknowns, questions/things to ask/consider at each step of the software estimation process, and some practical advice. This process is based on estimates I have done for multiple projects in the last couple of years.
Most software companies have to make decisions on whether to build a custom software or buy it from a vendor. In the last year I read many good articles on the web that helped shape my thoughts on how to approach these discussions. This article lists of questions that I have started to use to understand and make these decisions.
Sometimes you can’t make an informed decision because you don’t even know what should factor in to that decision. Shekhar Gulati is here to help provide those factors and he even produced this handy decision matrix for you.
Shekhar Gulati does a quick retro after his first year as CTO. Their lessons include:
And a few more.
