Lists of input and output information and sources EssayPrior to outlining the input and output information, the remains development life cycle must be in place so that the analysis is done accordingly. The correct nature of the inputs and the outputs would make the administration chassis vary accordingly as it requires to capture the information and put it into a frame to interpret in a decisive manner to take march on decisions. The strategys development life cycle for Bead Bar is as follows 1. Feasibility analysisThe new proposed system and the present operative system are analyse so that the ROI (Return On Investment) is obtained. The proposed system is pass on analyzed for economical, technical, schedule and other feasibilities so that it stands in front of all difficulties in the development of the project. The Bead prevention enterprises key management people are involved in the process of feasibility analysis. All the inputs, outputs and external environment are examine in detail so that the underlying intricacies would be researched well for their impact and development.Inputs Bead Bars inputs are in the form of companys short and long term objectives, its financial base and credibility for years to come, its general strategic plans, consent of the advisors and directors, risk handling strategies and many others. Outputs The feasibility has outputs in the form of higher management approval for the sustenance of the systems development, its full length use to cover all business functions, risk mitigation strategies and many others. 2. Systems proviso and requirements forumAfter the system is thoroughly checked for all its inputs and outputs, the requirements phase takes the lead. All the key stakeholders of the departments and the users of the system must be taken into account for gathering the crucial departmental functions, requirements and its interaction with other departments to achieve the central goal of the enterprise. Input It must be in the form of the users of the system who are better-off to derive and figure out the exact ground level happenings in the business.Their view of the workings of the enterprise must be captured so that appropriate implementation discharge be done. Output The valuable information fetched from the users of the system must be given(p) a representation and frame it accordingly to fix it into a system. 3.

The flow of data is analyzed so that the system captures the entire business cycle and their functions.Inputs It would come from the requirements gathering phase and the order of business flow. Outputs It would result in helping the analysts and designers in the process of database handling and further development of the system. 4. Database Model The database model for Bead Bar is as follows, which shows the interaction of the different entities of the business. Figure 1 Database Model 5. Coding The above design is given a representation of the business and the various functions are finally implemented at this stage.Inputs It is in the form of requirements gathered from the previous stages and the design documents. Outputs It results in certain implementation of the system so that it can be viewed physically. 6. Implementation and Training This stage correlates with actual planting of the system at the Bead Bar so that the present system is replaced and the proposed system takes its place. The users must be trained to operate the business functions with the system, store and retrieve data whenever it is demanded. 7. System feedback and maintenanceThe general working of the system must be responded back so that any form of negative points would be highlighted and discussed to take advantage of the system and technologies involved. 8. Systems Review and Maintenance schedule The review and maintenance schedule must include the following Preventative maintenance Maintenance schedules are a necessity for keeping the resources of a system in good health. The hardware, network equipments, communication programs and software must be periodically checked whether it is up and running (Mawer, 2000).
