Broy, E. Denert, Springer 2002 241 Tom DeMarco Structured Analysis: Beginnings of a New Discipline How it happened When I arrived at Bell Telephone Laboratories in the fall of 1963, I was immediately assigned to the ESS-1 project. This was a hardware/software endeavor to develop the world’s first commercial stored program telephone switch (now installed in telephone offices all over the world). At the time, the project was made up of some 600 persons, divided about half-and-half between hardware and software. There was also a small simulation group (a dozen people?) working to create an early prediction of system perfor- mance and robustness. I was at first assigned to the hardware group. My assignment was to de- velop certain circuits that enabled Emergency Action, the reconfiguration of processors when one was judged to have failed. This was an intriguing assignment since each of the two processors would diagnose the other and then try to decide together and agree on which one was incapable of furt- her processing – but somehow still capable to judge its own sanity. 242 Tom DeMarco To all of our surprise, the software for the project turned out to require a lot more effort than the hardware. -
MAKING DATA MODELS READABLE David C
MAKING DATA MODELS READABLE David C. Hay Essential Strategies, Inc. “Confusion and clutter are failures of [drawing] design, not attributes of information. And so the point is to find design strategies that reveal detail and complexity ¾ rather than to fault the data for an excess of complication. Or, worse, to fault viewers for a lack of understanding.” ¾ Edward R. Tufte1 Entity/relationship models (or simply “data models”) are powerful tools for analyzing and representing the structure of an organization. Properly used, they can reveal subtle relationships between elements of a business. They can also form the basis for robust and reliable data base design. Data models have gotten a bad reputation in recent years, however, as many people have found them to be more trouble to produce and less beneficial than promised. Discouraged, people have gone on to other approaches to developing systems ¾ often abandoning modeling altogether, in favor of simply starting with system design. Requirements analysis remains important, however, if systems are ultimately to do something useful for the company. And modeling ¾ especially data modeling ¾ is an essential component of requirements analysis. It is important, therefore, to try to understand why data models have been getting such a “bad rap”. Your author believes, along with Tufte, that the fault lies in the way most people design the models, not in the underlying complexity of what is being represented. An entity/relationship model has two primary objectives: First it represents the analyst’s public understanding of an enterprise, so that the ultimate consumer of a prospective computer system can be sure that the analyst got it right. -

Examining Capabilities As Architecture
September 2013 BPTrends ▪ Examining Capabilities as Architecture Examining Capabilities as Architecture Ralph Whittle Introduction This Article is a direct response to one written by Mike Rosen titled, “Are Capabilities Architecture?” [1] published in February 2013 by BPTrends It offers a different and contrasting point of view on accepting capability modeling and mapping as “architecture.” Business Architecture (BA) approaches and methods, while still evolving, have at least reached a point of maturity where the enterprise can fairly assess how it will develop and advance this initiative. As with any emerging field, a variety of approaches and methods will develop and enjoy success. From an historical perspective, consider the number of Business Process Management (BPM), Enterprise Architecture (EA) and Service-Oriented Architecture (SOA) approaches that have matured over the years. And no doubt, the same will eventually occur with the Business Architecture over the next few years. However, just as with the BPM, EA and SOA some different and contrasting points of view will find their way into the various Business Architecture approaches, techniques and methods. Today, at least two different and contrasting organizing principles are considered for Business Architecture. One is “capability centric” and the other is “process centric.” This article advocates and supports the “process centric” organizing principle, specifically using a value stream which is an end-to-end collection of activities that creates a result for a “customer,” who may be the ultimate customer or an internal “end user” of the value stream. The value stream has a clear goal: to satisfy (or, better, to delight) the customer.[2] This is a well known term, familiar in Six Sigma, Lean Manufacturing and BPM approaches. -

Faculty of Mechanical Engineering – Technical University of Sofia, Bulgaria Abstract: A software engineering (SE) process is a set of activities that leads to the production of software product. These activities may involve the development of software from scratch in a standard program language. However new software is developed by extending and modifying existing systems and by configuring and integrating off-the-self software or systems components. In the report they have understand the concept of software engineering, software engineering process models and when these models might be used.

But software engineering (CBSE) This technique assumes that parts of software is not just the programs also all associate documentation the system already exist. The system development process focuses and configuration data that is needed to make these programs on integrating these parts rather than developing them from scratch. operate correctly.

Chapter 1: Introduction
Just Enough Structured Analysis Chapter 1: Introduction “The beginnings and endings of all human undertakings are untidy, the building of a house, the writing of a novel, the demolition of a bridge, and, eminently, the finish of a voyage.” — John Galsworthy Over the River, 1933 www.yourdon.com ©2006 Ed Yourdon - rev. 051406 In this chapter, you will learn: 1. Why systems analysis is interesting; 2. Why systems analysis is more difficult than programming; and 3. Why it is important to be familiar with systems analysis. Chances are that you groaned when you first picked up this book, seeing how heavy and thick it was. The prospect of reading such a long, technical book is enough to make anyone gloomy; fortunately, just as long journeys take place one day at a time, and ultimately one step at a time, so long books get read one chapter at a time, and ultimately one sentence at a time. 1.1 Why is systems analysis interesting? Long books are often dull; fortunately, the subject matter of this book — systems analysis — is interesting. In fact, systems analysis is more interesting than anything I know, with the possible exception of sex and some rare vintages of Australian wine. Without a doubt, it is more interesting than computer programming (not that programming is dull) because it involves studying the interactions of people, and disparate groups of people, and computers and organizations. As Tom DeMarco said in his delightful book, Structured Analysis and Systems Specification (DeMarco, 1978), [systems] analysis is frustrating, full of complex interpersonal relationships, indefinite, and difficult.
