In some types of matrix orgs it makes sense as there is a distinction between project leadership and staff leadership.
- The staff/personnel manager is there for managing the engineers and getting their time allocated to projects. The 1:1s are for these managers to understand their engineers' skills, weaknesses, goals, and direction for growth/development so they can effectively allocate them.
- The team leads and project managers participate in standups so that the teams can effectively operate, work gets done, and project leadership knows what is happening.
The division makes sense when you have a lot of projects which may only be funded for parts of the year or where development isn't regular. Doubly so in industries which have a legal requirement for strong compartmentalization of knowledge & involvement. In these environments, your team leads, project managers, and standups will change like hats over the course of weeks, months, and years while you likely will only change personnel managers and 1:1s a few times over the course of a decade.
