I stumbled across this interesting article on how to choose useful titles for articles and chapters. I highly recommend reading the whole article, although I would point out the idea expresses in the bellow parragrah.
A third step is to consider using a full narrative title, one that makes completely clear what your argument, conclusions or findings are. Narrative titles take practice to write well. And they rarely work at the level of whole-book or whole-report titles. But they are often very effective for articles and chapters. One of my current best cited journal articles (written with colleagues) is ‘New Public Management is Dead — Long Live Digital Era Governance’. Here the title sums up the whole argument of the paper, and triggers two specific topics (‘New Public Management’ or NPM, and ‘Digital Era Governance’ or DEG).
