You take the initiative and develop a new feature, automate a task, increase productivity, optimise costs, or increase revenue. You would like to reap the benfits (promition, bonus) but not increase your workload or take the blame for bugs that are unavoidable in the new tech.
1. Automate tasks and keep it to yourself or your immediate team and hopefully work less.
2. Talk to your boss before you reveal your solution, such that he will 'discover' it and let it be his idea. Depending on your idea, this might be hard.
Any other ideas?
