I do managing, coding, design, governance and overall what i call "improve the company" within my areas of expertise and context switching and commitments are the most challenging things. Need to be very disciplined and know the other areas are currently very stable and under control to carve out time for the other things. It is not impossible but it have to be very focused and the problem domain need to be quite good understood before jumping in. Example, writing a internal tool that in worst case get delayed for later is easier to start working on then being part of customer facing product development as all of a sudden i would need to jump into some urgent management tasks or overall just let the governance and long term company quality go down.
