How Do Experienced Developers Estimate Task Time?

Task estimation can be tricky, especially if the tasks are non-standard. For routine tasks, you might estimate based on past experience, but for more complex projects, it can be much harder to predict. I find it's important to break tasks down and to be transparent about potential blockers early on.

A lot of us do something similar to what you're describing, but with a twist: we typically double the initial estimate. It’s a simple way to account for the unexpected. In my company, we have a process where the engineer gives an estimate, the engineering manager doubles it, and then the product manager doubles that again. Surprisingly, this approach works pretty well for us!

Experience plays a big role in getting better at estimating tasks. It's about knowing which elements can take time, like dealing with integration points or fixing issues that pop up due to technical debt. In my experience, I usually multiply my estimates by two or even three times to get closer to reality!

From what I've seen, a key part of effective estimation is learning from previous experiences. Track what you’ve estimated versus what actually happened. This way, you develop a better intuition for how long things will take. Sometimes, I just recommend aiming high with your estimates because if you finish early, it feels like a victory!

Consider using the Scotty Factor! It’s a fun way to remember that tasks often take longer than expected because of all the unseen complexities involved. Even experienced developers find themselves guessing at times but the Scotty Factor can help add a bit of cushion to your estimates.
