Long ago, when first building U.K. governments online / digital capabilities, our team learned, early on, about TTL. Time To Live. The lower that value the faster you could see the effect of changes you made to eg domain names.
Projects run on TTD. Time To Decide. The faster decisions get made, the faster you can see their effect and decide if you made the right decision or need to change your mind.
Project boards operate on a monthly cycle. In the time between meetings, a typical project has made hundreds of decisions that the board never even saw. Yet some decisions get held up, waiting for the board. There is options analysis, risk assessment, rework. Another board meeting. The TTD gets longer than the project.
It doesn’t work.
