Planning for the matrix master marketing inc.

Here are the some planning..

Requirements analysis- in this phase, developers determined the problems of company, what kind of system will the company need to solve these problems and the requirements needed in developing the system.

Design- in this phase, hardware and software requirements were determined so that the developers will know what kind ofcomputers or additional hardware and software will be needed in developing system.

Impementation- after creating the design, the developers will be creating small programs called units, which will be intergrated in the next phase. Each unit will be developed and tested for its functionality that is reffered to as unit testing.

Testing - in this ohase, the units that were developed in the implementation phase will be intergrated into a system after testing. Then the software that will were designed will go through constant software testing to find out if there are any flaws or errors. This would be done for the company not to face any problem during the installation of the software.

Maintenance - after the installation, modifications to the system or even in the individual component can be done to alter attributes or improve performance of the system. These would be done if the client initiates a request or defects that are uncovered during the used of the system. The client is also provided with regular maintenance and support for the developed software.
