I have founded four start-ups. 2 got failed, 1 was a profitable venture and the last is the one I’m still working on and have raised the seed round as well. As an entrepreneur, I have made many mistakes. But today I will tell you about the one that has the highest impact on my success or failure. It was something that I felt was not so important initially but after all these years I feel I was wrong. And the evil is a lack of documentation of key things I’m working on or need to work on. Being a passionate techie, I always believed in instant execution. It’s a good thing, right? Hmmm, to some extent yes but when you are working alone as a developer-only. If you are a founder or manager who needs to manage even a small team, documentation of key things becomes really important. Why? Let me tell you a small story. One day, I discussed something in a development meeting and I started working on dev tasks. Later, I had another meeting with the AI team and now, I remember my AI tasks and work on the same. What about left Dev tasks? Guess what I forgot. Even my developers and ML engineers could work only on those things that they could remember after we discussed. And as a manager, I could follow up on things only that I could remember. It resulted in 50% less productivity across the team. This number will be even horrible if you have a team of more than 4-5 people. So, if you also feel that you are working to your 100% but not getting 100% output then start documenting your work. It might not solve the problem but will help you to troubleshoot where you are lacking and on what things you are spending your precious time. For tasks management, I prefer Trello. And for getting those action items from meetings and meeting notes, I use Instaminutes (https://www.instaminutes.com/). We need to work smartly to outperform. Aren't we?
