A Project is a temporary, unique and progressive attempt
or endeavor made to produce some kind of a
tangible or intangible result (a unique product, service, benefit, competitive advantage, etc.).
It usually includes a series of interrelated tasks that are planned for
execution over a
fixed period of time and within certain
requirements and limitations such as cost, quality, performance, others.

PROJECT IMPROVEMENT
1. Creating something new (like in your example an e-book);
2. Improvement project where there is a performance gap.
Examples: reduce lead time of lead conversion, improve customer satisfaction, reduce customer claims and irritations, etc.
In the improvement projects I follow Project Management steps called DMAIC. This stands for the following project phases:
Define (describe the problem and set the objective),
Measure (collect baseline data and check quality of data),
Analyze (brainstorm and select the most important causes of the current performance vs objective),
Improve (counter-measures and actions based on the most important causes),
Control (if performance is significantly improved compared to baseline, create new working procedures and checklist to make sure results are sustained).
All of these phases are carried out together with a multi-disciplined team who knows the most of this problem.
