I've found the following books to be very influential in getting projects over the finish line. I wouldn't advise you to follow exactly what each book says and implement it verbatim, but rather read each book and understand the underlying principles and implement the bits that are most relevant to your needs. The aim is to build up your own 'toolkit' of methods and approaches to use as necessary. This demonstrates the necessity for developers to be constantly researching the field of software development both online and in written publications. These books are written by some of the industry's leading figures.
