ugs in the software can go unnoticed. An example of this was when an Atlas-Agena rocket veered off-course when it was ninety miles up. Ground control had to destroy the $18.5 rocket. The reasons for this - a missing hyphen. However there are many more reasons for software systems failure, and most of them are due to human negligence that leads to software failure. There are two types of software systems failure. These are in the design stage of the software or in the implementation of the software. These are the main reasons for systems failure.Poor software design - Fundamental flaws in the design of the software.Incorrect requirements specifications - The brief is inconsistent or missing vital information. Political / Commercial pressures - This can lead to developers skipping parts of the system to save time or money. There are also cases of rivalry between sub-contractors, which damages the design of the system.Incorrect analysis and assumptions - Predictions based on incorrect assumptions of the real world or its behaviour.Not properly tested software implemented in a high risk environment - This is almost guaranteed to lead to systems failure.Poor user-interface - Makes it difficult or even impossible for the user to operate the software system.Incorrect fit between software and hardware - Incorrect specification of the hardware type in the brief, or upgrading the hardware without upgrading the software (or vice-versa).Inadequate training given to the operators - The people who have to use the software are not taught properly how to use the software system or they are expected to learn on their own. Over reliance on the software system - The operators expect their software system to work in all conditions and to perform miracles for them.I will be looking at these types of systems failure with examples. 2.1 Poor software design- the Denver airport automated luggage handling systemAn example of poor software design is the Denver In...
