So my query was whether tool(s) can help permeate some of this culture in a large company and thus reduce or eliminate the manager who would otherwise have been unproductive not only from the perspective of marketing or for the company, but potentially also have demotivated the Sr.Engineers or just in case he/she was not a good manager ?
Tools: at Boostable we had Aha (https://www.aha.io/). And we would have the founder Alex split the tickets up. Aha would disseminate the tickets into Pivotal Tracker (https://www.pivotaltracker.com/).
Aha played a really big role in top-down delegation of tasks and equating them to business objectives. That software is pretty cool and I recommend checking it out, because I think in some cases it can make manager's redundant.
After that, it was autonomous. I created a lot of issues by myself directly in Pivotal (which probably lends to them not being recognized officially, since Aha was where the business impact was overviewed)
