New Team and Lessons Learned
The past few months I have been building a new team at GitHub focused on solving problems for our business teams. Here are a few valuable lessons we learned along the way.
Solving the right problem
We solve problems for a living and we have one major constraint, our time. This means we need to be thoughtful in choosing which problems to solve. We cannot solve them all.
We decided to solve employee expenses at GitHub by building our own expensing system. We had evaluated 3rd party services and while they did 90% of what we needed, that last 10% made it seem like it was worth doing on our own.
What we failed to account for were the other opportunities, the other problems that needed solved, that ultimately would have a more lasting impact on GitHub.
If we use our company vision, to help people build software better together, as a framework for deciding what to work on, choosing the right problem to solve becomes much easier.
We should be sensitive to opportunity costs. Solve the problem that will have the greatest impact with the lowest cost.
After choosing the wrong problem to solve we did not set clear goals so that we knew what success or failure meant. As a result it took us four months to realize we were working on the wrong thing.
Our first goal was to ship a system that received receipts, connected them to transactions, provided automatic and manual classification, and then entered the data into our accounting system.
The more I learn about software development, or solving any problem really, the more I realize a winning percentage requires breaking down problems (and their solutions) into smaller and smaller pieces. Shipping quickly and constant iteration mean faster course corrections and less costly failures.
The fact that we could not easily break the expensing problem down into smaller pieces should have been a red flag.
We can reduce the costs of failure, both emotionally and economically, if we fail fast. We can’t fail fast unless we ship quickly and iterate.
Do the simplest thing first
We also started building a platform for different teams (and apps) at GitHub to be able to easily invoice customers. We dreamt up the perfect platform for invoicing, without having tried the simplest thing first.
The lie we often believe is that we understand what our constraints will be in a week, or a month, or six months and therefore we can save time by optimizing early. The truth is that we cannot foresee the future.
In the end we learned that invoicing integration needed to be built inside of the products it serves first. After it has been proven it can possibly be extracted into a shared service. This sounds like more work in the long run, but ultimately this process can adapt to change more quickly and easily.
One more thing
We could have avoided a lot of heartache and wasted resources if I had sought mentorship from people with more experience and context at GitHub.
For long term success I need to constantly be learning, which means keeping an open mind and a humble spirit. I look forward to the journey \m/
