A good technical strategy provides a map for the journey towards your North Star goal.
Are you responsible for a horizontal program like optimizing your cloud infrastructure costs, or improving the overall security, reliability, or data quality posture? Are you evaluating a greenfield, broad, ambiguous problem space and wondering where to start? Or, are you building infrastructure or leading a multi-year effort, with significant error margins due to unknown unknowns?
For all such situations, when dealing with ambiguity over a long time horizon (at least 12-18 months); when the stakes are high, as is the investment and the impact; when you need to make decisions with measurable confidence, spanning multiple teams, and drive influence without direct authority, you need a technical strategy.
