If you cannot take a firm bid / no-bid decision within the first 5 – 10% of time, you will erode valuable time which should be spent developing and capturing your response.
Likewise, if you do not allow 5 -10% of time for a final review and edit, you risk sending an incomplete or unchecked document.
Bid Management
To give yourself the best chance of success, allocate 5 – 10% of the available time at each end of the bid process for up-front decision making and final review.
