Review of "Structured Requirements Definition, by Ken Orr." Ken Orr and Associates, Inc.

tors design will require a "minimum of two percent of th e total program cost ." This is a small price to pay if the process produces appropriate user interfaces . Chapter 5 also discusses the process of "function allocation." Here Woodson presents a strategy for allocating system functions between people and machines . Although hi s examples here, and elsewhere in the chapter, focus on military systems, the methodology can be generalized for an y system-development project . Although the Human Factors Design Handbook ha s rather limited applicability to the design of computer systems, I still find its pages becoming more tattered than mos t of the books on my bookshelf. The book, like the Guinness Book of Records and Bartlett 's Familiar Quotations, is fun to just open to any page and start reading .
