Written Reports — When and How

The written report is the most powerful format for complex analysis that must stand alone as a reference document. A well-constructed written report can be shared, retrieved, cited, and acted on independently — without the author present to explain it. It carries its own reasoning. It can be read in depth or scanned for key findings. It serves the reader who wants to understand the analysis and the reader who wants only the conclusion. The format's weakness is also its strength: it requires the writer to complete the reasoning, not merely gesture at it with a bullet point.

1. Executive summary as a standalone document The executive summary of a written report should function as a complete document for the reader who reads nothing else. It should contain the key findings, the primary recommendations, and the most critical risks. The reader who finishes the executive summary should know what was found, what should be done about it, and what the most important risks are. The body of the report provides the depth for those who need it. The executive summary is the deliverable for the executive; the full report is the deliverable for the working team.
2. Section architecture that mirrors the decision Structure the written report around the decision the client is making, not around the process the consultant followed. The structure "Methodology → Findings → Analysis → Recommendations" reflects the consultant's work process. The structure "Current State → Gap Analysis → Options → Recommended Direction" reflects the client's decision frame. The report organized around the decision makes the client's reading task easier and the recommendations more directly actionable.
3. Sentence density calibrated to the audience Written reports for senior executive audiences should have fewer, denser paragraphs — each paragraph advances the argument rather than elaborating on it. Reports for operational working teams can carry more detail per section. A report that uses the same density throughout — or that uses the density appropriate for an operational team when the primary audience is the C-suite — will lose one audience or the other. Know the primary reader and calibrate the density accordingly.
