TPM should be a centralized function reporting to the head of engineering. Although TPMs represent a tiny fraction of the engineering team, they support the success of cross-functional engineering programs and deliver the most complex projects.
TPMs should constantly be automating and inventing, implementing light processes for the team, or teaching someone basic program management techniques–looking for how to make themselves unnecessary so they can work on solving the organization’s new challenges. I often tell people, tongue in cheek, that if we meet our goals we will work ourselves out of a job. Of course, in a company experiencing rapid growth, the business and scale issues mean there are always new problems to tackle. But solving problems systemically is a core tenet of high-performing TPM teams.
