Parallel Construction

Sentences and lists are awkward when they contain a series of items with inconsistent grammatical structure. But as your reader scans through a series of items with parallel grammatical structure, the relationships between different items of information become clear. Here’s an example:

Which of the two sentences below is easier to follow?

At the February meeting we will hold a discussion of the new health plan, whether to revise the procedures manual, and then a draft will be developed of the early retirement policy.

At the February meeting, we will discuss the new health plan, decide whether to revise the procedures manual, and draft an early retirement policy.

In the second example, the parallel verb tenses saved space and helped us grasp the ideas immediately. To help your writing flow smoothly and make sense, use the same format for items you present in a series.

      We prefer “We will undertake the following projects:” over “The following projects will be undertaken:” but either is acceptable.
      After that, any items beginning “We will” or “We will be” are repetitious of the introduction. We recommend:

      We will undertake the following projects:
      a. Commencement of Phase II of the …
      b. Launch of a new website and mobile app
