The To and the Do, or the Do and the To?

A helpful tip I give to people in my writing classes is to start proposals or time-sensitive requests with a sentence that includes a to and a do. The to is the reader benefit; the do is the writer expectation.

Here are some examples of the to and the do:

1. To improve our chances of winning the account (to), please include an analysis of options in the proposal (do).
2. We can reduce rental costs, increase our labor pool, and facilitate the production process (to) by relocating the plant to Memphis (do).
3. I recommend including an analysis of options in the proposal (do) to improve our chances of winning the account (to). 
4. Relocating the plant to Memphis (do) will reduce rental costs, increase our labor pool, and facilitate the production process (to).

Examples 1 and 2 appear in the order of to and do, a more deferential style; Examples 3 and 4 are in the order of do and to, a more assertive style. Choosing the right approach depends on the situation and your relationship with the readers.
