An open, spiral-bound notebook rests on a light-brown wooden desk or table

An open, spiral-bound notebook rests on a light-brown wooden desk or table. The ruled page inside the notebook displays handwritten project management calculations. These include a tabular chart at the top with columns for activity labels (A-H), optimistic time, most likely time, pessimistic time, preceding activity, and calculated 'Te' values. Below the table, a formula for 'Te' is written. The central part of the page features a network diagram, consistent with a Critical Path Method (CPM) or Program Evaluation and Review Technique (PERT) chart, depicting numbered nodes (0, 1, 2, 3, 4, 6) connected by arrows representing activities labeled A through H, each with an associated duration. Further down, the text "To determine the ET the project to be Completed" and "Critical path" is written. A human hand, with visible fingers, rests on a white object situated to the immediate right of the notebook. A darker wooden object, possibly an armrest or part of another piece of furniture, is partially visible in the upper left quadrant. The scene depicts an indoor academic or study environment. No specific visual information within the image identifies a precise location within the city of Ihiagwa, Nigeria.
