Answer Posted / ravinderpal singh
1. First phase : Recognition of need
The trends of increasing technical complexity of the systems, coupled with the need for repeatable and predictable process methodologies, have driven System Developers to establish system development models or software development life cycle models.
2. Second Phase : Feasibility Study
Feasibility for a system means whether it is practical and beneficial to build that system.
1.Technical feasibility: Can the development of the proposed system be done with current equipment, existing software technology, and available personnel? Does it require new technology?
2. Economic feasibility: Are there sufficient benefits in creating the system to make the costs acceptable? An important outcome of the economic feasibility study is the cost benefit analysis.
3. Legal feasibility: It checks if there are any legal hassle in developing the system.
4. Operational feasibility: Will the system be used if it is developed and implemented? Will there be resistance from users that will undermine the possible application benefits?
3. Third phase : Analysis
analysis find the fact by below techniques:
Sampling
Questionnaires
Interviews
Observations
Research
4. Fourth Phase : Design
5. Fifth Phase : Development, Implementation & Testing
6. Sixth phase : Post Implementation & Maintenance

Assignment A software house got a project to automate sales/purchase department of a furniture store. The store management is clearly transferred their requirements to the software house management. There is no chance of changing the requirements afterwards. Software house management use waterfall process model to make the project. Given is the progress flow of water-fall process model In waterfall process model, the deliverable (document) produced in one phase serves as an input to the next phase. Suppose you are a project manager who is leading this project. It is decided to work and complete the project using waterfall process model approach. You are required to develop a plan in which the key task is to decide the deliverable that should be built during and after completion of each phase. Also give a description or required contents that must be included in those deliverables. You are not supposed to make the complete project. All you are required to do is to make a Project plan. In that, you need to give a set of deliverables (documents) which according to you, should be developed in each of the phase (Requirements, Designing, implementation, Testing, Maintenance). Also provide contents which should be there in each deliverable. The contents should be clear and have brief explanation. Note:: There are one folder and one file in the attached folder. The file is named as Assignment 4 write-up which is your assignment write-up. The other folder named Project deliverables is the folder in which you are required to organize and place your deliverables. Name of the document/deliverable saved in each folder should be mentioned in the file named checklist (This file is placed in the “Project deliverables” folder) For Example If you produce a deliverable named Requirement Specification (RS) in the “Requirements” phase. You need to do following tasks 1) Finalize the RS contents 2) Save the file in sub-folder named Requirements 3) Write the name of this document in the checklist file under the heading Requirements. Similarly, you need to make and save deliverables of each phase. Not all phases contain one deliverable. There must be some phases having more than one deliverables. PLEASE SIR PRIVIDE ME THE CHECK LIST FOR GIVE SENERION ? CHECKLIST ARE: 1-Requirements 2- Designing 3- Implementation 4- Testing 5- Maintenance
