Data Representation Techniques
Visual and other structured formats (such as charts, tables, and matrices) used to present and communicate data and information.
Key Points
- Turn raw data into clear, decision-ready insights for stakeholders.
- Common forms include charts and graphs (Pareto, histogram, control chart, scatter), tables, matrices (RACI, risk matrix), dashboards, and heat maps.
- Choose the technique based on the audience, the type of data, and the decision or message required.
- Effective visuals are accurate, readable, and emphasize the key takeaway without clutter.
Example
A project manager analyzes defect logs and uses a Pareto chart to highlight the top defect categories, a risk probability-impact matrix to summarize risks for the steering committee, and a milestone chart in the weekly status report to show schedule progress.
