The centrality of quality specifications means significant gains for the broadest spectrum of stake-holders who stand to win with the System Of Interest (SOI). Take this specification as an example to clean up:
"The new system will use Foo language running on OS Bar and ensure top industry quality response time on web requests."
People in the field have seen specs like these. Hopefully you aren't writing them. There are what Gilb classifies as "Major defects" in this spec. Which web requests, the front page or all of them pulling from the various databases? Can the old system be incrementally upgraded instead of an entirely new development environment? Why use Foo and Bar if something else gets the job done better, faster, and with less resource utilization? Just how fast is "fast", anyway?
In Competitive Engineering you're told to get measureable quality requirements, record who requested that requirement, and exactly what "success" is defined as. That allows you to go back to the requester with notes such as "If we use OS Baz we'll get a 27% increase in CPU performance" and let them make a decision or escalate to the project funder. You're also encouraged to weed out "design constraints"; at least out of the mandatated and into the labelled area "Design Constraint". Wouldn't it be great if you got a specification that let you design the best you could without technical input from someone that can't use a web-browser?
See if you can understand my re-write of the above spec into Planguage.
Response Time on Front Page of Company Website.
Type: Performance Requirement
Version: 1.2
Status: Draft
Owner: F. Flintstone
Stakeholders: Marketing, Server Support, Corporate Intelligence, ,
Ambition: The front page of the corporate website should respond fast enough to keep the viewer's attention.
Description: Marketing research indicates the typical business website viewer makes an opinion on the website, and thus the company, within 20 seconds. Our corporate site pulls data from three different databases and a sizeable image library, taking an average of 26.87 seconds on a home DSL/Cable modem equivalent network. Marketing advantage can be gained if we can grab viewer attention noticibly faster than our two nearest competitors who average 23.43 and 26.09 seconds, respectively.
Vision: Enough accurate information provided quickly enough to keep the customer on our site.
Scale: Time, in Seconds, to a complete front page load on the equivalent of a 250K network connection.
Past [Front page, 1 Apr 07]: 26.87 seconds
Goal [1 November 07]: 19 seconds <- Marketing Director: BR
Stretch: 15 seconds
Wish: 9 seconds
Design Constraint: Supportability <- Server Support Manager WF Must utilize
Design Constraint: Security <- Corporate Intelligence BB Must meet
------------------------ end of spec example --------------------
Probably the only thing that might confuse you about that specification is the use of text within "<...>". Planguage uses that to denote a "fuzzy requirement"; something that is defined but not with the concreteness you'd like. In this example, however, it would be relatively simple to query B. Rubble for the specific guidelines her team seeks to enforce. The use of fuzzy requirements also allows for change over time; more OS versions may become supported while others are obsolete.
When I read part of an electronic copy of the text I had a problem. My antiquated home printer could not print it and if I used the work printer I view the output as a possession of my employer. The book is written as part instruction, part reference manual; I bought my own copy because I know I'm going to use it for the next few years and several employers.

It's a very good book.Review Date: 2007-01-16
Thinking... further ;o)Review Date: 2006-03-12
The main concept of Competitive Engineering is Planguage, a word created mixing plan and language. Communication is the basis for working together. This is why Tom Gilb emphasises first the creation of a common vocabulary. He states that his glossary could be considered as the best contribution of this book. Beneath the definition of a common language, for me the "hidden agenda" of the book is to help us to think... further. The common language is only a tool that helps us express our thoughts more precisely and completely.
Fortunately for us, Tom Gilb didn't only write a dictionary of system engineering. A large part of the book is devoted to the activities of system engineering and project management. Based on Planguage, Gilb gives us a framework to elicit clearer requirements. He emphasises a measurable vision ("bad numbers beat good words") and presents tools to achieve this objective. He also helps us separate requirements from design. He devotes an entire chapter to quality control. Finally, there is a presentation of the techniques of evolutionary project management that supports incremental development based on the priority and impact techniques described in previous parts of the book.
In every chapter you will find examples and case studies that help to visualise how the concepts translate into practice. There is also an "additional ideas" part that presents material for further thinking. Beneath the seriousness of the topic, Gilb also manage to place some lighter parts and you will find how to compare seriously apples with oranges.
At the end, your realise that you have a book where process is not opposed to people, structure is not opposed to flexibility, precision is not opposed to allowing change, documentation is not opposed to active refinement, Gilb's proposed solution is not opposed to customisation for your needs. It is just a book that gives you new inspiration to deliver better software solutions to your customer.
If you are interested in software process improvement, you can read this book from the beginning and find practical material to examine your current practices with a different vision. If you are a lonesome project manager or developer, you could begin by just using the index to get Gilb's view on your current activity or problem. Be cautious, because there are many chances that you will be tempted to read more material ;o)
After reading this book, I browsed again my old copy of "Principles of Software Engineering" that I bought when it was published in 1988. I saw that many ideas from "Competitive Engineering" were already presented in this book. Tom Gilb just applied to his ideas the same concepts he proposes for system engineering. He refined, expanded and structured them to get a better product. The printing industry has just prevented evolutionary delivery, but you can bet that he will find a way to include this in the future.
Best Practices in Systems Engineering and ManagementReview Date: 2006-04-06
The book's subtitle is "A Handbook for Systems Engineering, Requirements Engineering, and Software Engineering Using Planguage". The term "Planguage" is central to an understanding of the book. Planguage, which is derived from a union of "plan" and "language", is the methodology for implementing CE. Much of the book is devoted to describing the generalized processes, rules, and vocabulary of Planguage. Tom notes, "Planguage should be viewed as a powerful way to develop and implement strategies that will help your projects to deliver the required competitive results." Fundamentally, the book presents a new take on best practices in systems engineering and management.
The book is useful on several levels. For organizations without a formal or documented process, tailoring of Planguage would jump start the process at a high level of maturity. For organizations that have achieved CMMI level 3 status, Planguage by itself is not as useful. However, many of the ideas of CE-the Planguage methods-are worth considering for enhancement of existing organizational processes. Tom states that CE is "about technological management, risk control, and breakthrough improvement in complex business systems, projects, and processes." CE is a believable approach for delivering complex projects on time and within budget.
The book passed my value-added test, when I realized that I was photocopying several pages for future reference, to be part of my "toolkit" of helpful tips and techniques. I particularly enjoyed reading the 10 often witty, summary principles in each chapter. Two examples are:
* The Principle of `Storage of Wisdom': "If your people are not all experienced or geniuses, You need to store their hard-earned wisdom in your defined process. Capture wisdom for reuse, Fail to write it, that's abuse!"
* The Principle of `The early bird catches the worm': "Your customers will be happier with an early long-term stream of their priority improvements, than years of promises, culminating in late disaster."
About 30% of the book is the Planguage Concept Glossary, which Tom views as a central contribution of the book. I focused my attention on the other, more interesting, parts of the book, which describe the main CE/Planguage methods of Requirement Specification (RS), Design Engineering (DE), Impact Estimation (IE), Specification Quality Control (SQC), and Evolutionary Project Management (EVO, also known as Evo). RS describes an approach for identifying all types of requirements while avoiding ambiguity and also planning for change. Functional and performance requirements are distinguished. DE deals with identifying, choosing, and prioritizing the order in which design ideas are implemented and delivered. In conjunction with Evo, DE selects the design ideas most likely to provide a significant benefit for early delivery.
SQC is an eminently practical approach for evaluating the quality of any technical document via sampling measurements. An hour of SQC early in a project can save almost 10 hours of rework. SQC also provides a means to assess the success of process improvement efforts. IE provides a realistic method for evaluating-in quantitative terms-the effectiveness of designs in meeting both the requirements, especially critical performance attributes, and the resource budgets.
Evo focuses on early, frequent delivery of project results via a series of high-value, small evolutionary steps. An ideal Evo approach would divide the project into a series of cycles. Each cycle would consume 2-5% of the total financial budget and 2-5% of the total project time-while delivering some measurable, required results to the stakeholders. The next cycle is selected to deliver the best stakeholder value for its cost (highest ratio of value to cost, or highest ratio of performance to cost). Although an ideal approach can't always be realized, Tom provides some convincing examples to argue that there is always a solution to making a project evolutionary (small steps with critical deliveries first).
Perseverance pays off with Competitive Engineering. The book is not a quick read, which Tom acknowledges. You have to carefully study some of the pages to understand the concepts being presented. The reward occurs when you glean the nuggets of wisdom from the numerous practical examples, case studies, and Planguage examples. Tom's way of presenting the CE concepts makes the book a useful addition to the systems engineer's library.

Good tutorial of basic control systemReview Date: 2002-06-22
One drawback with the book is it only covers PID control and its variants, but doesn't cover state-space control. While state-space control may be considered "overkill" by many control engineers, state-space is used in industry. The decision to use state-space is often not in the hands of individual engineers, so it may not be an option to ignore state-space. It would be nice if Mr. Ellis could cover state-space in his next edition of the book.
Clear, complete, concise, and practicalReview Date: 2007-12-21
1. To bridge the gap between the control theory from school and the systems that I now design and build
2. To gain insight on how to improve the performance and reliability of real motion systems
3. To find ways to apply advanced techniques to help meet challenging performance requirements
I got all of this and more from this book. The topics covered clearly and concisely in this book span three courses I took at Cal Poly SLO: basic controls, digital controls, and modern/advanced control theory. Mr. Ellis does a great job of quickly introducing these topics and getting straight to the practical implications.
The free software and examples work well to illustrate his points quickly and easily while helping to commit the insights to memory. I also hope to use it as a training tool for our techs.
I highly recommend this book to anyone working with control systems, especially grad students and people getting started in the field. I look forward to reading his book on observers.

Facing MeReview Date: 2008-03-17
Update from a family memberReview Date: 2005-01-26
For anyone struggling with epilepsy, either as a patient (as my wife) or as someone who loves an epilepsy patient, this is a must read. For anyone affected by a chronic medical condition, either as a patient or as a family member, it is a must read.
For the one carrying the heavy burden, you will hear the voice of one who has "been there." For those of us who deeply love one so afflicted, you will learn much of what it means to be in your partners shoes (something you must learn).
Twenty years ago, we would have given almost anything to hear this story from another. You should listen.
Here is my original review:
"An excellent tale of struggle with epilepsy (which mostly means struggling with society's view of epilepsy) and the self-accepted stigma which often accompanies it. This is not a technical medical story, as much as it is a patients account. As such, it is less involved with precise medical details than "what is it like" to go through metamorphosis. As the tale continues through brain surgery, and the author's effort to understand her place in the world without epilepsy, there is a freshness and genuineness which comes from a patient's point of view, illuminated by her faith in God's active presence.
A great read for anyone with a chronic medical condition, those in relationship with them, and for anyone who could use a dose of hope."
R. Eric Sawyer
Peace amidst BrainstormsReview Date: 2005-01-19
During a time in her life when she needs the most support, she endures misunderstanding, a lack of support from her community and overwhelming nights of the soul. After undergoing surgery she has new challenges, unexpected surges in her creativity and entire new worlds to explore. She is mentally unprepared for all the changes that start to occur, and as the seizures disappear, an overwhelming depression threatens to undermine all her previous efforts at healing.
Will her faith in God give her the strength she needs to overcome her fear and discouragement? Will the surgery be a success and will she be able to live a fulfilling existence and find hope in a seemingly hopeless situation?
Stephanie S. Sawyer's story is fascinating because she reveals many aspects about epilepsy that are essential for understanding the fear, struggles and discouragement this invasive challenge presents. Stephanie's writing is vivid, inspiring and informative.
Since 181,000 new cases of epilepsy are diagnosed each year and ten percent of the American population will experience a seizure in their lifetime, this book is essential reading.

Facing Me Powerful and InspirationalReview Date: 2004-07-14
Even if you're not much of a book reader, you'll find yourself clutching Facing Me, which details Stephanie Sawyer's personal struggle with Epilepsy. She displays incredible courage dealing with the disorder, the brain surgery she endured and the post-operative experiences that followed.
Epilepsy is a frightening disorder. It strikes anytime and anyplace. It can leave you exhausted and embarrassed and its threat is something the epileptic never forgets. The epileptic is on-guard every minute of every day attempting to hide a constant concern.
But in spite of the never-ending challenges, the author never gives up. She maintains a positive attitude, refuses to give up and has brain surgery. With the surgery comes depression, a dark and frightening ordeal when the simplest task can be overwhelming.
Five years after the surgery - just as Stephanie was certain her seizure disorder was gone for good - she had another seizure. The thought of another seizure after certain victory had to be devastating, but Stephanie didn't give up. She continued to share her musical talents, graduated from Moores School of Music in 1999 and has proven an incredible inspiration.
I know about Epilepsy and I also know about the surgery. I, too, suffered from the disorder and had the same surgery as Stephanie. That said, I can say first-hand that Facing Me is a phenomenal book written by a spirited and courageous person who has refused to give up against all odds.

At times it reads like a textbook, and some of his analogies with scientific discovery and history are long-winded, but all in all this was a book that made me think differently about how I act as a leader. It's very different from the standard stuff I have read before on leadership, managing and parenting. This is a book of well thought theory and examples. There is a lot of meat in this thing and it requires active reading skills.

Adventuresome LeadershipReview Date: 2007-11-02
The themes include the necessity of a sense of adventure and the possession of courage in leaders, the importance of self-differentiation, focusing on strengths instead of catering to weaknesses, the destructive nature of relationship triangles and the challenges leaders face among followers.
He highlights some negative practices of leaders in our culture, mainly the over-dependence on data and information and the misplaced emphasis on emphathy over action.
In this book, readers will find practical, simple ways to improve leadership. This book will challenge some of the accepted practices of organizational leadership today and should open readers' eyes to necessities of effective leadership.
All of Friedman's themes are applicable to families, congregations, businesses, government, etc. This is an especially useful book for parents and pastors/rabbis.
The downside of the book is that it was published posthomously, so the last three chapters were collected by colleagues who also edited the book. The effect is that it is not as cogent and concise as it might have been if Friedman had lived long enough to complete the writing himself.
This is a dense book on leadership that is definitely worth the effort of reading, as it will change the way you lead and relate to others.

You may laugh or may cry, but you won't put this book downReview Date: 2006-11-30
This is not a dry, mechanical review of how ethical decisions are made. Quite the opposite, the book captures your full attention from the very first page. You become fully involved in the heart-wrenching lives of actual hospital patients, as well as the no-win situations health care professionals and family members find themselves in when struggling with decisions that literally have life or death consequences.
For example, when she describes the process in which the life support devices are withdrawn from a young patient you feel you are there in the room witnessing the tragedy. Some readers might scream within their minds not to do it - perhaps there is something else can be done? Others may feel a sense of loving compassion over the ending of someone's suffering. Both types will feel incredible compassion for those who had to make the actual decision and hopefully will never have to make such a choice in their own lives.
Inside Texas Medical Center...Review Date: 2007-01-31
The book is in a very easy-to-read format - the stories of the patients she follows are all intertwined throughout the book. For example, you'll read about Patrick for 30-or-so pages, and then she'll switch over to update you on Taylor's story. She does this because you are reading the stories in "real time" as they happened; all of this took place in a certain time span in the hospital. It's exciting and fast-paced non-fiction - I read it in two days and didn't put it down.
It will break your heart, because often the ethics committee has to bring money into the discussion, as much as they would like to treat every patient as if money was not an issue. This book is SO worth reading, for anyone who is interested in medicine and healthcare at all.

Penetrating AnalysisReview Date: 2008-03-17
The history is followed by an examination of the perspectives of each of the three major groups that make up the state of Iraq - the Sunni Arabs, the Shi'a Arabs and the Kurds. Though this structure entails a certain amount of repetition of information from the first section of the book ( especially in the section on the Shi'a), it does help us understand the position of each of the three groups and what they stand to gain or lose as a result of different potential constructions of their future.
The third section of the book is devoted to examining the options available for the future of Iraq, including their potential positive and negative consequences and the likelihood of prevailing conditions allowing each option to become reality.
All three major groups in Iraq are shown warts and all. The book shows no favoritism in its analysis. The issues are analyzed with penetrating depth and the belief of the American government that the people of Iraq would welcome Western style democracy with open arms is scathingly laid bare as the ludicrously naïve position it is. A must read for all who truly want to understand the situation in Iraq.

Future history of IraqReview Date: 2006-07-02
First, the monarchy from 1920-1958;
Second, the revolution from 1958-1968;
Third, the Ba'ath Regime from 1968-1988;
Fourth, the wreck of Iraq from 1988-2003.
These chapters recount the history of Iraq from its beginnings after World War I--when the British created a country where none has existed before--with three parties holding very different views--Sunnis, Shiites, Kurds.
Each of these three groups is examined as the basis for speculation as to what is to come in the future. The authors wonder if Iraq might end up splintering into three distinct countries--Sunni, Shia, and Kurd. Questions emerge from this scenario: Is this desirable? Would the needs of all three groups be optimized in this manner? Will this encourage additional "ethnic cleansing"? Even beyond what we have seen? Would such a solution mark success--or failure--of the American intervention?
The future? America's role in that future? We cannot say at this point. However, it does appear that the American intervention never really understood the historical and cultural context. We can only hope that the Iraqi incursion turns out well. But it is also clear that Americans sadly misunderstood the context into which they entered. . . .
Iraq History 101Review Date: 2006-03-12
Each element is well done and provides context for the reader interested in something more than current events weith respect to Iraq. The end result of reading this book is to wonder at the arrogance of the war planners who apparently did not consider historical and ethnic and religious context as that critical for the outcome of the war. As one of the neocons once mentioned, reality is not so important to the United States; the country can create its own reality. To this point, the reality being created on the ground in Iraq is far different than it might have been had history acted as a guide.
