Define Project:
A Project is temporary state of work. It is temporary in nature. Each and every project will have a start and end. It also has two outcomes one is success and the other one is failure.
Example:
Lets take an example "watching a movie in cinema" is our project.
Start:
Planned to book the tickets, started from home and watching movie in cinema is the start of our project.
End:
Watched movie successfully and reached home safely is the end of our project.
Success:
Once he/she watched the movie successfully.
Failure:
If he/she did not watch the movie.
Risk Analysis:
Every project might have a risk. We have to do work arounds to solve those kinds of risk. Those work arounds also called as mitigation.
Example:
Lets go back to our example, here there might some kinds of risk can happen before and during the project.
Risk Before the project:
There might be some kinds of risk can happen before the project.
Those kinds of risk are
1. There might be raining when you want to start from your home or
2. Your father might be stopped you to go to cinema
Risk during the project:
There might be some kinds of risk can happen during the project too. Remember here our project is "watching a movie in cinema"
Those kinds of risk are
1. You might get a call during the movie or
2. Your child might be crying
SDLC:
SDLC is a structure imposed on the development of a software product. It may vary from project to project. Here we have the common structure that might come in a project.
Phases of SDLC:
SDLC abbrevated as software development life cycle.
It includes various things like
1. Project Goal Definition
2. Requirement Analysis
a. High Level Requirements
b. Low Level Requirements
3. Planning
4. Design
5. Development
6. Implementation
7. Testing
8. Production
9. Maintenance
Lets see explanation of above with the example our project called "watching a movie in cinema"
Project Goal Definition:
Project Goal provide the overall context for what the project is trying to accomplish. Every project will have a goal.
Example:
Here the goal of our project is "Watching a movie in cinema".
Requirement Analysis:
Requirement analysis defines collect client requirements and analyse it.
It can be treated as
a. High Level Requiements
b. Low Level Requiements
High Level Requiements
High level requirements defines the specific thing.
Example:
In our project watching a movie in cinema is a specific thing. Here the client will say hey dude i am going to watch a movie. Here he will not explain how and where he wants to do.
Low Level Requiements:
Low Level Requirements is derived from high level requirements. Low level requirements defines the detailed thing of the specified one.
Example:
Lets take our example watching a movie in cinema. Here a client should say when he is going to watch, where he is going to watch and how he is going to watch. These are the low level requirements.
Planning:
Scheduling and Budgeting can be done in planning.
Example:
Here we have to make sure buying the tickets for a movie in what time, where to and in what budget those kind of things comes under planning.
Design:
Design phase will be done according to our requirements. Client discusses with a System Analyst what functions are needed and what the outputs should look like.
Example:
In our example, we have to ask the client during the interval of the cinema what type of snacks he wants, those kinds of things comes under this phase. Depends on his/her requirements we will make the arrangements.
Development:
The development phase occurs, where actual programming is done here
Testing :
The testers test for errors in the syntax of the code and ensures that the logic of the programs obtains the desired results.
Production:
The application is placed into use. The Systems Analyst will then train the end user on how to use the system.
Maintenance:
The maintenance stage occurs when a change needs to be added to a program. This may occur because additional information or functionality is required out of the application by the end user.

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
