Another point of contention is how optimistic you should make your business plan. The problem with making over-optimistic predictions and plans is that these plans could well go wrong. Unforeseen circumstances can always put a spanner in the works. Therefore, it's wise to err on the side of caution when it comes to devising your business plan. Indeed, it's wise to predict conservatively and prudently when it comes to assessing the possibilities of future targets, sales and profits. A worst-case scenario will always prove to be less of a shock than one that raises expectations too high.
Since your executive summary leads your business plan, it is important that you carefully construct this first section. In fact, the executive summary is so important that it is placed directly after the title page, even before the table of contents. Many find that writing this key section works best when completed last. The executive summary serves as a synopsis of all the sections of the business plan. If you wait until the end, you will be better able to write a cohesive and complete executive summary.
