Specification text:

$$A client company that sells a new digital gadget needs a specific

editorial content management system to manage product manuals that

are written for customers. Engineers write and submit drafts of product

manuals. Reviewers check these manuals for their technical accuracy

and the quality of writing $($so that customers can understand them$).$ There

is a list of reviewers $($an audit committee$)$ who can review and evaluate

the submitted manuals. The chief editor will distribute the manuals to

relevant reviewers $($those that have the necessary technical knowledge$).$

The reviewers then submit their reviews$/$comments and a score to the

system. The chief editor will make the decision about accepting the

manual to be published online or to reject the manual and return it to the

engineer. The chief editor then notifies the engineers about the status of

their submission.$$
