Pie is an alias for our product.
Me and 10 co-workers are working on different kinds of pies, and people are generally assigned one pie to work on (or multiple people on one pie, but never multiple pies per person).
Whenever people are assigned to a new type of pie, they mostly choose one which fits their interests and which they find exciting. I generally choose less "exciting" pies so that others can work on pies they like, but this seems to be a mistake. After I have worked on a pie for X months and have made some cool improvements on it, co-workers develop more attention for it.
As a result, when the grouping is changed, people are eager to work on the pie that I initially developed. This often leads me to be assigned to a new pie, and the process repeats. When I look back on the pie that I initially developed, the progress has stagnated.
Is this a known problem? I find it hard to tell people that they only want to work on a certain piece because I have made it that way, and that them wanting to work on it too will only slow down the progress.
