Project format: The project development workers are divided supported the project that they work as shown below diagram. In the project format, a group of engineers is appointed to the project at the beginning of the project and that they stay with the project until the completion of the project.
Thus, the identical team carries out all the life cycle activities. Obviously, the functional format needs a lot of communication among groups than the project format, as a result of one team should perceive the work done by the previous groups. Skip to content. Change Language. Related Articles. Therefore it needs to be updated with the need on the go.
Usually the development in this approach takes longer time as it is language-dependent. Whereas in the case of assembly language, the development takes lesser time as it is fixed for the machine.

Writing code in comment? For example, you can not use a RAD method for a problem solution where the problem definition is outside of well known or similar systems definition.
In this case, you may have components within the problem that are not addressed by the RAD system to be used for implementation of the solution. Therefore, a more fundamental approach may be required as is the case with the NHS e-booking system. For our project, we have chosen the traditional waterfall model System Development method for implementation.
The phases in this approach are illustrated in figure xxx. There is also Software System Development methodology which is a sub-component within the overall system development methodology. In addition, there are also other methodologies related to other aspect of the system development and implementation methodology. In order for a given system development methodology to be feasible, its individual methodologies must be consistent and compatible.
System analysts usually employ at least one methodology, especially the structured analysis techniques which results in visualisation of system components that are of particular interest to the analyst. The more recent formal methodologies can be categorized as follows: Process driven Data driven or Object Oriented.
This is the traditional approach as stated in section xxxx above. As can be seen from figure xxxx all steps in this traditional approach are executed in sequence as listed in section xxxx. The following diagram illustrates the stages in this model and gives a hint on why it is called the water fall model. Figure xxx The traditional approach to the development of the system life cycle. Each stage in this approach follows in sequence of the previous stage as listed in section xxx.
The project uses the traditional waterfall methodology as there were problem areas of web base software implementation that has never been solved. The Internet poses a challenge for the development and deployment of software system with functionalities that meets the requirements of a wide and varied user audience.
The overall aims of our test and evaluation plan is as follows: To determine that the online booking system implemented delivers the performance as stated in the original system objectives and that it meets the expectations of stakeholders.
Redundancy kept to a minimum, recoverability, how fast is it, Input Data Validation to ensure correctness of user input HCI and Usability Issues - are stakeholders satisfied with performance of the system System Control Structure and Robustness - Scalability of system - can it handle small and large data values?
