Do what you say
Do what you say you’re going to - when you say you’re going to do it. It can be difficult to get everyone on board, to get decisions and feedback on time and to gain consensus, especially with a large group of people. But it’s essential to keep the process on schedule as procrastination can seriously disrupt the whole process.
Make sure you factor in reasonable time for discussion and debate as this will give you a chance to iron out any differences in the time available.
