Hi Tanveer
The report system that works for me sets down the story in structured layers.
1. The essence of the dispute
2. The contractual substantiation
3. Description of cause and effect for each delay event with snapshots of the programme embedded in the text with call out blocks to emphasise particular points.
4. Short cogent sentences each sequentially numbered.
5. A simple summary either at the beginning or the end.
What you must not do is:
1. Produce massive charts with colours and arrows all over the place which places all events at once and is the graphic equivalent of a fireworks display.
2. Long protracted paragraphs with rambling sentences.
3. Say the same thing more than once.
4. Use roman numerals.
Good luck in your new career.
Best regards
Mike Testro
