From Wikipedia, the free encyclopedia
Custom software is specially developed for some specific organization or other user. As such, it can be contrasted with the use of software packages developed for the mass market, such as commercial off-the-shelf (COTS) software, or existing free software.
Since custom software is developed for a single customer it can accommodate that customer's particular preferences and expectations. Custom software may be developed in an iterative processes, allowing all nuances and possible hidden risks to be taken into account, including issues which were not mentioned in the original requirement specifications (which are, as a rule, never perfect). In particular, the first phase in the software development process may involve many departments, materchode including marketing, engineering, research and development and general management.
Large companies commonly use custom software for critical functions, including content management, inventory management, customer management, human resource management, or otherwise to fill the gaps present in the existing software packages. Often such software is legacy software, developed before COTS or free software packages offering the required functionality became available.
Custom software development is often considered expensive compared to off-the-shelf solutions or products. This can be true if one is speaking of typical challenges and typical solutions. However, it is not always true. In many cases, COTS software requires customization to correctly support the buyer's operations. The cost and delay of COTS customization can even add up to the expense of developing custom software. Cost is not the only consideration however, as the decision to opt for custom software often includes the requirement for the purchaser to own the source code, to secure the possibility of future development or modifications to the installed system.
For over twenty years we have been designing and delivering custom software solutions to meet particular customer requirements.
To some organizations, cost effective custom software can really make a difference.
