I recently re-read this book, first published in 1991, and found that - despite all the changes which have occurred in the business world since then - most of its material remains solid and relevant. In the Preface, H. James Harrington observes that organizations "are thinking differently about their processes. Processes are no longer viewed as just production processes. Today (i.e. in 1991), management realizes that that there are many processes that use material, equipment, and people to provide many types of outputs and services. They are called business processes, and today they are even more important to competitiveness than production processes." In this context, I am reminded of what Peter Drucker asserted (in 1963) in an article which appeared in the Harvard Business Review: "There is surely nothing quite so useless as doing with great efficiency what should not be done at all." Presumably this is what Harrington has in mind when suggesting that "automating a bad process not only ensures that we can do a bad job every times but that we can do it faster and with less effort than before."
Harrington carefully organizes his material within ten chapters, followed by an appendix that provides "Interview Guidelines." His pragmatic approach throughout the narrative focuses on what to do to initiate and then sustain business process improvement (BPI):
Focus on business processes
Set the stage for BPI
Organize for process improvement
Use flowcharting to draw a process "picture"
Understand the process characteristics
Streamline the process
Use measurements, feedback, and action to "load, aim, and fire"
Qualify (i.e. establish credibility for) process
Benchmark process
For me, some of the most interesting and valuable material is provided in Chapter 5, "Understanding the Process Characteristics." Harrington identifies five (Flow, Effectiveness, Efficiency, Cycle Time, and Cost) and explains what must be done to get them in proper alignment (hence the importance of a flow chart) in terms of people involved, objectives to be achieved, strategies and tactics to be executed, measurements, evaluation, and modification.
As they embark together on a journey to achieve the desired objectives, they should realize that they will be involved in a marathon, not a sprint. They must be persistent but patient.
Those who share my high regard for this book are urged to check out sources which were published later, such as Dan Madison's Process Mapping, James R. Press's Process Improvement and Process Management, Process Improvement Essentials: CMMI, Six SIGMA, and ISO 9001, John Jeston and Johan Nelis' Business Process Management: Practical Guidelines to Successful Implementation, and Paul Harmon's Business Process Change: A Manager's Guide to Improving, Redesigning, and Automating Processes.
