I manage a small team of developers on an application which is in the mid-point of its lifecycle, within a big firm. This unfortunately means there is commonly a 30/70 split of Programming tasks to "other technical work". This work includes:
Working with DBA / Unix / Network / Loadbalancer teams on various tasks
Placing & managing orders for hardware or infrastructure in different regions
Running tests that have not yet been migrated to CI
Analysis
Support / Investigation
Its fair to say that the Developers would all prefer to be coding, rather than doing these more mundane tasks, so I try to hand out the fun programming jobs evenly amongst the team.
Most of the team was hired because, though they may not have the elite programming skills to write their own compiler / game engine / high-frequency trading system etc., they are good communicators who "can get stuff done", work with other teams, and somewhat navigate the complex beaurocracy here. They are good developers, but they are also good all-round technical staff.
However, one member of the team probably has above-average coding skills, but below-average communication skills. Traditionally, the previous Development Manager tended to give him the Programming tasks and not the more mundane tasks listed above. However, I don't feel that this is fair to the rest of the team, who have shown an aptitute for developing a well-rounded skillset that is commonly required in a big-business IT department.
What should I do in this situation? If I continue to give him more programming work, I know that it will be done faster (and conversly, I would expect him to complete the other work slower). But it goes against my principles, and promotes the idea that you can carve out a "comfortable niche" for yourself simply by being bad at the tasks you don't like.
