1. Set boundaries and definitions
Define the operations, locations, period, and topics covered. Explain key terms and what is excluded so readers can understand the scope of each claim.
Define boundaries such as facilities, suppliers, business units, and reporting period before comparing results. If boundaries change between years, disclose the change so readers do not mistake it for performance movement.
2. Use traceable evidence
Identify data sources, collection methods, and any estimates. Distinguish measured results from goals or projections, and do not use attractive graphics to obscure uncertainty.
For each metric, identify units, data owner, source, calculation, and estimate method. Keep source notes close to charts so readers can understand what the number represents.
3. Present progress and gaps
Show the baseline, current result, and target when those values are available. Report setbacks and limitations alongside progress to give readers a balanced account.
Avoid using broad labels such as “green” without a measurable definition. Present targets separately from achieved results and state when data is incomplete or not comparable.
4. Review claims before release
Ask subject experts to verify figures and wording, and obtain legal or assurance review where appropriate. Keep a record of evidence supporting every material public claim.
Use an evidence review before release and preserve the supporting records. A digital annual report can provide organizational context, while an impact report focuses on outcomes.
