Why Do We Need Software Engineering by an pedia

This history will enable us to comprehend the issues that began to become obvious from the late sixties and early seventies, as well as the solutions which have contributed to the development of the area of software technology. These issues were known by some as "The program Crisis," so named for the indicators of the issue. The crisis is far from over, but as a result of the evolution of several new methods which are currently included under the name of applications engineering, we've created and are continuing to make progress.

In the first days of computing the key concern was with constructing or obtaining the hardware. Software was nearly expected to care for itself. The consensus held the "hardware" is "difficult" to alter, while "applications" is "soft," or simple to modify. According, many people in the business carefully planned hardware improvement but gave considerably less forethought into the computer software. If the software did not work, they thought, it would be simple enough to change it before it did work. If that's the situation, why attempt to plan?

The expense of software amounted to this tiny fraction of the expense of the hardware that nobody believed it quite important to handle its own development. Everybody, however, watched the significance of producing programs which were efficient and conducted quickly because this saved time around the pricey hardware. People time was supposed to conserve machine time. Making the people procedure effective received little priority.

This strategy proved satisfactory from the first days of computing, once the software was easy. However, because computing improved, applications became more complicated and projects grew bigger whereas apps needed since been routinely established, composed, operated, and maintained all by precisely the same individual, programs started to be developed by groups of developers to meet somebody else's preferences.
