We run a test case against one of the best frameworks out there and one that we use every day to build our company NextJS, in this use case we try to show how a slow build time will reflect the cost for a company, so you can extrapolate and make some thinking about the current state of your CI.
A slow CI pipeline is crippling's your company ability of building and shipping value faster because it increases the feedback loops between iterations and wastes the most valuable asset of the company developer's time
Today a slow build is costing your company per developer between $ 121 ~ $ 96, if 5 developers are waiting for that build that cost goes up to the range of $ 606 ~ $ 481.
With a build time between 1 hour 37 minutes ~ 1 hour 17 minutes
Annually that cost is ~ $ 28.275 per dev, which represents 18.85 % of their salary
With the change of 1 line
the cost of that will go down for 1 developer to $ 45 ~ $ 32 and ****for 5 developers to
$ 225 ~ $ 163. With a build time between 35 minutes ~ 26 minutes
Annually that cost is ~ $ 9.212 per dev, which represents 6.6 % of their salary
if 1 dev is waiting for 1 build a day that will represent ~ 1 h 27 min wait time * 75 USD / H * 260 days of work in a year → $ 28.275 Annually cost per dev
~ 30 min wait time * 75 USD / H * 260 days of work in a year → $ 9.212 Annually cost per
