Due to the high costs for creating and maintaining complex programs, haulage software development is performed by developers using a structured (project) plan. This plan (the process model) divides the development process into manageable, temporary and limited phases.
Thus, haulage software is completed step by step. The phases are closely interlinked throughout the development process. In practice, specific methods are used and they involve multiple stages of system analysis, system design or concept and subsequent implementation, and testing, for example, prototyping,
This software technique involves the entire process from identification of needs through to the commissioning of a specific IT solution. The main objective is the provision and implementation of an application software, in part, plus the necessary hardware and networks. Projects are often undertaken by or with external service providers but also often as in-house development.
Depending on the project type, there are additional approaches to project development. From a very structured approach through various mixed forms to highly flexible, they include open methods, such as agile software development.
Accordingly, there is also a distinction between top-down and bottom- up approaches. The above sub-steps of software development are not necessarily completely through in every project. Rather, individual processes are chosen specifically for each request. This is necessary from the viewpoint of cost and management reduction.
Implementation phase
In the implementation phase, the previously designed application solution is technically realized through configuration of software products. A rebuild of haulage software is usually by programming, that is, the individual functions, objects classes are coded in a programming language using an integrated development environment.
The test procedure is usually carried out in collaboration with the end users of the client. It is in software development than normal, that programs are flawed. Sometimes even whole parts have to be completely re-implemented, thus reprogrammed.
Since in complex applications can not be excluded with certainty that amended parts of the program can not influence about other program functions (side effects), a renewed complete test of the whole system should be done after fault clearance.
Software implementation
The finished haulage software accompanied by any required standard software products, hardware is then (an Application Service Provider) partly filled during the installation on the computer systems of the customer or the operator and made operational.
For larger projects, often done initially only one installation on a test system or for a few pilot users. The subsequent extension (installation and commissioning) to other locations is called rollout. An essential part of the project is the introduction of support, particularly in the form of training or instruction of end users, power users and administrators.
