Configuration Management: Theory, Practice, and Application

Configuration Management is a common thread that ties the various departments and organizations together, facilitating coordination of effort.

Testing, failures and inability to duplicate.


Testing and Repeat-ability 

Repeat-ability of testing results is important to establishing cause and corrective actions. If it is not possible to repeat the sequence of events leading to a failure, it is not possible to replicate and therefore difficult solve the cause of the fault or failure.  The steps that evoked the problem are necessary to replicating the problem – only sometimes that seemingly does not work.

Testing and Configuration Management

Things like a specific system configuration may be implicated in the failure, testing to find a failure on one configuration after having found the problem on another configuration, does not mean the failure does not exist.  This is another link between testing and configuration management.

Repeating the test with some fidelity requires documenting the test steps with some diligence as well as trace-ability of the test specimen, all parts are not created equal.  When it comes to software or embedded products the latter is very true as it is … Continue reading


Configuration Management Book


 

 

Early Reviews

Just finished reading Configuration Management: Theory, Practice and Application, and I must say this is the most comprehensive document I have ever read on the subject. It addresses theory, practice, and application, with many real-world examples of what happens when the principles of product/configuration management are not followed! —Bill Dawson, SVP Product Management, Volvo Group

… the definitive guide to configuration management. No configuration manager should be caught without a copy of this book. … explores not only the technical aspects of the field, but the practical applications of configuration management in a wide variety of industries not just the technology field. —Joe Townsend, Configuration Manager, Indiana Public Retirement System

… captures the essence and significance of configuration management. It provides the framework, tools, and practices that will enable any enterprise to successfully create and manage a framework for CM in a mass customization world. … A much-needed book and discussion at a critical time in … Continue reading


Intention and Follow Through


The Civil War

It was the United States Civil war, the battle was Gettysburg.  There was no doubt, General Meade had the intention to defeat Robert E. Lee.  In the end General Meade was victorious and his congratulatory order to the troops was also sent by telegraph to the War Department (and would be read by Abraham Lincoln). The crux of the message was the invaders had been driven from our soil.

Later, President Lincoln would meet with General Mead:

Do you know, General, what your attitude towards Lee after the battle of Gettysburg reminded me of?” Meade replied: “No, Mr. President – what is it?” Lincoln said: “I’ll be hanged if I could think of anything else but an old woman trying to shoo her geese across a creek[1].

Follow Through

In the President’s mind, Meade had left the job unfinished.  He had not pursued the rebels after the battle.  General Mead had good intentions, … Continue reading


Concurrent Engineering Problem Part 2


Concurrent engineering problem take many forms

From our last blog, we have learned that of an organization that has concurrent engineering difficulty, specifically coordinating the design work.  We will further explore this situation.  One of the subsystem groups decides to improve the coordination effort internal to that specific department. For example, System 1 chooses to focus on their handling of the design coordination internal to that department. This is not a bad idea, as there are some inefficiencies and losses due to ineffectual coordination of the various subsystem designs. 

 

 

There is another problem area, and that is the coordination of the systems that comprise the entirety of the product.  Below is a graphic that illustrates this other area lacking coordination.

 

Where to start?

The trick is to understand the best area upon which to focus the finite resources.  A short sample period, a portion of one large project, provides and example of the costs due to errant … Continue reading


Concurrent Engineering Problem


Once upon a time

There once was a company, with a systemic problem with concurrent engineering and change management.  This was a complex organization, with many functional areas.  Each functional area, had sub-function divisions.  This type of organizational structure is often referred to as a functional organization with the associated hierarchy.  These various functional areas design and produce sundry parts that will be assembled together to produce a complex electro-mechanical and embedded software system.  A partial drawing of the structure is provided below:

 

Concurrent Engineering Requires Coordination 

 Within the systems level, there are sub-system levels.  These subsystem levels are departments within the systems department. Each sub-system focuses on a unique aspect of the entire system.  There work has some commonality, for example system 1 could be the electrical / electronics engineering discipline.  Work within this department is coordinated to meet that of the entire system.  Generally speaking, these departments are often co-located, under those circumstances internal department communication can … Continue reading
