The Software Crisis • The most visible symptoms of the software crisis are o Late delivery‚ over budget o Product does not meet specified requirements o Inadequate documentation • Some observations on the software crisis o “A malady that has carried on this long must be called normal” (Booch‚ p. 8) o Software system requirements are moving targets o There may not be enough good developers around to create all the new software that users need o A significant portion of developers’ time must often

What Is Computer Software? When you think of a computer imagine a machine made of two parts. The first part is the computer hardware‚ the physical parts of the computer that you can actually touch. Some examples of hardware are disks‚ monitors‚ boards‚ chips‚ etc. Hardware does all of the physical work of the computer‚ from memory storage to display. The second part‚ what we call “computer software”‚ acts as the brain of the computer‚ telling the hardware what to do and when and how to do it

1. Can you explain the PDCA cycle and where testing fits in? Software testing is an important part of the software development process. In normal software development there are four important steps‚ also referred to‚ in short‚ as the PDCA (Plan‚ Do‚ Check‚ Act) cycle. Let’s review the four steps in detail. Plan: Define the goal and the plan for achieving that goal. Do/Execute: Depending on the plan strategy decided during the plan stage we do execution accordingly in this phase. Check: Check/Test

Software Crisis Software crisis was a term used in the early days of computing science. The term was used to describe the impact of rapid increases in computer power and the complexity of the problems which could be tackled. In essence‚ it refers to the difficulty of writing correct‚ understandable‚ and verifiable computer programs. The roots of the software crisis are complexity‚ expectations‚ and change. The major cause of the software crisis is that the machines have become several orders

TORA Temporary-Ordered Routing Algorithm (TORA) – An Operations Research Software TORA is an algorithm i.e. a mathematical set of instructions or programs (mathematical-software). It is an optimization system in the area of operations research which is very easy to use. Further‚ TORA is menu-driven and Windows-based which makes it very user friendly. The software can be executed in automated or tutorial mode. The automated mode reports the final solution of the problem‚ usually in the standard

response possible for a given group of customers within a well-defined geographic area for a given product or service over a specified period of time under well-defined competitive environmental conditions. We will further split up this definition: 1. Market potential is the maximum demand response under certain assumptions (ultimate demand). 2. Relevant customer for the product and service. It is not merely the present consumer but also the potential consumer so that maximum possible demand is achieved
