Tech Stack

Document your decision process for every level of your tech stack. There are a few options available, including:

Pro/Con List

You could do a simple pros/cons list for your options:

Database	Pros	Cons
Oracle DB	Some stuff	Other Stuff
MySQL	Some stuff	Other Stuff
mongoDB	Some stuff	Other Stuff

Decision Analysis Matrix

Alternatively, you can try to quantify things with a decision matrix:

• Make a column for each factor you find important.
• Assign each column a weight denoting its importance (e.g. 1-not that important to 3 - extremely important)
• As a team, rate each technology candidate in each factor on a scale of e.g. 1-5
• Sum up the weight*rating across a row to get that candidate's overall score

Database	Cost	Maintainability	Existing Documentation	Team Interest	Sponsor Interest	Score
weight	(1-3)	(1-3)	(1-3)	(1-3)	(1-3)	-
Oracle DB	(1-5)	(1-5)	(1-5)	(1-5)	(1-5)	=sum(weight*rating)
MySQL	(1-5)	(1-5)	(1-5)	(1-5)	(1-5)	=sum(weight*rating)
mongoDB	(1-5)	(1-5)	(1-5)	(1-5)	(1-5)	=sum(weight*rating)
