As a CEO you would do this. At the department level. Split them by probing for rifts between departments. Prioritize one group's project over another. Use department lack progress as dirt on that side's leadership. Get leader replaced and bring friendly face. Now both sides are friendly and open to better policies. As a manager pretending to be CTO let them do what they want or you will be seen as the problem. Look for power shifts between departments and ally with the correct side. If your company wanted a strong CTO they would have hired or promoted someone. If you want to be in a position to be a strong CTO make powerful friends or get promoted and gather experience and win some awards.
