There are lots of tools
As you come across more tools with fancy features, you’ll be tempted to implement them all. But this is a trap.
Tool evaluation and switching is yak shaving. It makes you think that you’re doing something useful, but it’s just useless busy-work, most of the time.
Most tools have nearly identical features
There is rarely, if ever, a single killer feature that makes using a tool a necessity.
Features are almost always nearly identical so switching from one tool to the other provides little, if any, value.
So focus on making use of existing tools as fully as you can
After you select a tool, you should make full use of it.
Make sure your team can use them
The key criterion for selecting a tool is how many of your team members can already use it well. You should be heavily biased towards this.
Otherwise, it takes a lot of time to use them properly
You won’t have enough time to integrate and use them to their full extent.
Furthermore, using fewer tools means you can get complete context in each.
