Defining & Producing Specification Firstly, the problem must be carefully described, this can be achieved by speaking to the user/manager The problem is then defined in writing and agreed by all parties involved The specification is then defined as a set of actual deliverables (to be achieved through the project) Specification will focus on what the new system will need to do to enable users to carry out their tasks (functional perspective) Establish the inputs, processing requirements and output needed What hardware or software requirements or anything else that will facilitate the solution (network cabling, desks, chairs, routers, security software)

Описание слайда:
Planning & Designing The Planning & Designing stage and the Collecting Information stage more or less happen simultaneously, with each part providing information that might tweak another aspect of the process In the Planning & Designing Stage: Plan the project Identify review points and other milestones Consideration of what resources will be needed What money will be required to complete the project What are the deadlines

Слайд 6
Описание слайда:
Collecting Information While the planning & designing stage is going on, information about the existing system and processes are collected, collated and analysed You cannot design a solution if you do not understand what you have already! Collecting Information involves Interviews Questionnaires Data Analysis Meetings Document Analysis Observations

Описание слайда:
Implementing Implementation part of a life cycle includes: Creating the project product (whatever that might be), so building your interactive website Any testing that needs to be undertaken, testing you completed website Often project teams can underestimate how much time will be needed for this phase, since developing a product, such as a website, can take longer. At this stage it is sometime better to heavily overestimate than to underestimate (and therefore carry out more effective testing)

Слайд 8
Описание слайда:
Completing & Reviewing Once the project is complete, the product is activated or brought to life and is tested All team members in the project will get together to review its success, using the original functional specification, to provide a list of performance criteria against which success or failure can be judged Review will highlight a number of aspects for immediate resolution or an additional wish list of enhancements In the event that the client wants or needs additional enhancements, in a commercial project there will be an opportunity to charge extra for the additional work
