Flexibility
You have control of the formatting of all elements of the summary – a better plan your way.
You can include any milestone, task or summary task and any combination of these in your summary.
It is quick and easy to make changes; add a new line, group items into a new swim lane, change colours and names, amend the time scales or add comments.
Able to receive data from a wide range of sources (MS Project, Excel, Primavera etc.) – anything that can generate a table of dates should be able to drive your summary.
You can output in any format Visio can save to (including PDF and JPEG) or copy and paste out into any suitable program.
The same plan can drive many summaries for different audiences.
You can summarise more than one plan at a time.
