I've learned that Engineers approximate and use π = 3. So now we've gotten our time estimate down from 4x to 3x. Talk about efficiency!

- rectang 3y agoPi is more accurate than 3. I like pi.
- iamerroragent 3y agoπ , numerically, is only as accurate as you approximate it to. 3 can be used as an approximate for π.
- sumtechguy 3y ago3 is the number I have heard many times from different PM's. Engineers tend to interpret a bit 'how long will it take' is 'how long will it take YOU'. So you say 2 weeks. The PM is thinking plus QA, plus rework, plus shipping. That usually is about 3x or ~6 weeks.
- danaris 3y agoBut that extra time is the PM's job to add on, not the engineer's. If you ask an engineer "how long will it take," you should expect to get back "here's how long it will take me," not "here's how long it will take me and the other people you manage".
- sumtechguy 3y agoYou are exactly correct but that is not what people really ask. It takes awhile for engineers to realize it. By that time they are stressed out and do not know how to manage the PM. The PM is usually not a subject matter expert they manage tasks. They do not even know they need those things. So they fully expect you 'the expert' to know it. Is it 'right' not really, but it is reality and a side effect of how many people become PM's.
