Programming is a critical aspect in computer system development. It is therefore essential for to be keen enough and have the expertise to avoid the common system mistakes that often occur. According to Blackheath and Jones (2016) the following are some of the issues that may arise because of system misunderstanding;
Incorrect coding: This can be because the software code specification was either omitted, incorrect or misinterpreted during programming.
Delegate your assignment to our experts and they will do the rest.
Complex nature of the software: Software that is difficult to use and maintain has a higher risk of being defective with any wrong data or when changes are made.
Obsolescence: Hardware and software changes may cause incompatibility with the older version of the software.
Incorrect and inadequate software interfaces: This happens when a system does not accept input from other systems or when an output from a system cannot be read by other systems.
Lack of security controls: When unauthorized persons are allowed to access the system, they may add or omit essential data. Users may overwork the system beyond the recommend system’s capacity.
Inconsistency: Some software is made explicitly for one environment. Anytime changes need to be made, or users need to move its performance is interfered with. Sometimes it may fail entirely.
Slow system responses to inputs due to overworking or software’s inadequacy.
Problems that May Arise in Implementation of the Specification may include
The dynamic nature of technology: Innovations will always appear however many systems may be updated. Implementation of a specification, therefore, is a continuous process.
Inaccuracy: the programmer may attribute software’s problem to something different from the real cause.
Inaccessibility to past defect reports by the user. This could be due to miscommunication or total unavailability.
Cost: Many resources may be used in areas like purchasing new items, movement, and testing the system.
The complexity of the user needs: sometimes users’ needs do not fit within a system’s capacity.
Incomplete software documentation: Some specifications may have been taken as self-evident by manufactures, but in a real sense they are not.
