A signature is our handwritten imprint on a document for authenticity.
A signature is also a unique identifier for what is distinctly us, like DNA and fingerprint.
Your work, too, deserves a signature. It deserves a sign of authenticity, and if you are proud of that work, mark it yours. If the quality of the work is not to your par, then don’t put it out.
Just as importantly, the work is itself a signature. Innovation is as much about doing something new as it is doing something you. An easy and sobering way to decide is to first write down all the components of a project onto a list. Then, strike away all the parts that could be accomplished by someone else. Your team will always solve those problems. But if nothing is left, then you have learned that the project doesn’t need you.
That which remains, then, is uniquely you. It’s your value-added. Your signature.
