Many people in the software industry have been working this problem. Early system development efforts were concerned with keeping the hardware up and running.

As the hardware stabilized and became less expensive, the emphasis in systems development shifted to software engineering considerations. The demand for more intelligent information technology systems is increasing as enterprises attempt to implement effective knowledge strategies. What is needed are systems that process data and produce information that enables the enterprise decision makers to make informed decisions.

Such systems are intertwined with many organizational facets of the enterprise, and the life of a system generally exceeds the tenures of individuals within the enterprise. One consequence of this continuing trend is that systems are increasing in their complexity, and thus software systems development is resource intensive. Concomitant with the resource and system complexity issues is the recognition by enterprises that they need to reduce their dependence on transient system developers.

The decision makers are searching for more effective software systems development strategies. There are no simple solutions..

1 Business Case Figure 1 15 illustrates three awt Code 3/9 possible approaches for effecting software process improvement within an enterprise management edicts, corporate process improvement policy, and systems engineering environment. Management Edicts As an enterprise grows, so does its complexity. An individual s capability to maintain pace with the expansion correspondingly diminishes.

Replicated across an enterprise, the management edict approach often leads to the competing fiefdoms or subcultures. Over the long term, the result undermines organizational effectiveness. More organizational resources are poured into internecine struggles rather than being directed toward furthering the goals of the enterprise.

Corporate Process Improvement Policy As an enterprise recognizes its expanding requirements for effective knowledge strategies, it often formalizes its vision for software process improvement with corporate policy. Such policy heightens the corporate awareness of the need to change the way software systems are developed. Often this approach does not reach down to the dayto-day working level of activities.

Changing how the work in progress needs to be accomplished is disruptive and can lead to unhappy customers. While well-intentioned, this first step in software process improvement often falls short of influencing how systems are actually developed. Systems Engineering Environment (SEE) This software process improvement approach extends down to the day-to-day development activities.

As discussed in this book, the SEE (1) accounts for the increasing complexity of issues associated with enterprise growth, (2) accommodates the problems of transient developers, and (3) serves to overcome development subcultures within an enterprise. The SEE consists of two complementary components:. Do it my way! OK, Boss!

This book focuses on the SEE approach..

1 Business Case Application Development Pro cess Environment (ADPE) the set of those policies, guidelines, procedures, and standards defining the processes for developing deliverable products (i.e., documents or computer code or databases).

A policy is a high-level statement of principle or course of action governing software activity. A guideline stipulates a sequence of broadly stated steps for producing a software product or accomplishing a software process. A procedure is a detailed prescription for the sequence of steps to accomplish some software-related activity.

A standard stipulates format and content conventions for software products or stipulates activity conventions for software processes. The ADPE is a framework for bringing about consistent product development. Application Development Technology Environment (ADTE) the technology as embodied in hardware and software development tools, and associated procedures for their use, required to develop products.

These tools include, but are not limited to, CASE tools, programming language compilers, LAN application development tools, PC application development tools, database management systems, configuration management tools, and project management tools. This book provides guidance on how to develop and implement application development process environment (ADPE) elements (i.e.

, policies, guidelines, procedures, and standards) to support the practical development of software products. This environment helps to increase the likelihood of developing usable products on time and within schedule by infusing engineering discipline into the process. Through this discipline infusion, the development process is transformed from an ill-defined process (i.

e., lacking repeatability) to a welldefined process (i.e.

, one that is visible and traceable). We believe that visibility and traceability enable both customer and product developer management to communicate effectively with one another. They can make intelligent, informed decisions regarding how product development should proceed.

This communication helps to remove ambiguities and misunderstandings. We believe practitioners are better positioned to (1) provide the customer with usable products, (2) repeat their successes and avoid their mistakes, and (3) reduce reliance on individuals for these repeatable successes. We recognize that some in the software industry have observed that software engineering is not a discipline.

Peter J. Denning, former President of the Association for Computing Machinery (ACM), made the following observation:38 Software engineering is not a discipline. Its practitioners cannot systematically make and fulfill promises to deliver software systems judged by their customers as usable and dependable, on time and fairly priced.

The illusion that software engineers possess a discipline has produced the major breakdown called the software crisis.. 38 P.
