INTRODUCTION
In this assignment the requirement is to collect information or requirement to implement a System Design to record customers ordering placements in Car Spare Parts for Smart Arcade Car Spare Parts Company that are currently using a manual system. This allows the company to record customers ordering placements to sell car spare parts to the customers. Nowadays in some of the companies in the World use this type of systems to sell their products throughout the country.
There are five tasks in this assignment to be done. In the first task of this assignment I have explained about stages of software requirement specification such as feasibility study and requirement gathering, design, coding, testing, maintaining and many other sub areas of the SDLC stages and also I have planned a model for the proposed system and I have mention about the advantages gain by proposing the planned model to the proposed system and I have added some attractive images too. The Second task of this assignment is to create a feasibility study report, system functionalities such as sending email for the customer regarding registration payment and many other payments and also I have explained about different feasibility criteria such as time, cost, and scope feasibility. The third task of the assignment is to create a software requirement specification for the proposed system to this task I have about hardware requirement, software requirement, functional and non-functional requirement, purpose and I have given a conclusion to it. . Next task in this assignment is a designing part here I have drawn four diagrams such as the ER diagram, Context Diagram, Level 0 DFD and level 1 DFD for the proposed system. In the Final task of this assignment about the quality management and I have Evaluate how user and systems requirements have been addressed with reference to the SRS developed.
When doing this project I had to search details from the internet. I had to search some of the car spare parts ordering websites to get an idea on what I have to do. Finally by seen these websites I got perfect idea on how to do it. In this project I’ve explained everything in a simple way.
 
Task 1 — Requirements analysis and selection of a SDLC model
SDLC (Software Development Life cycle) is the process of developing software through few steps. SDLC has number of phases such as Feasibility study and requirement gathering, designing, construction; testing and maintaining through these phases the product go forward and ends up with a developed product without an error.
There are different types of SDLC models such as,
 Waterfall model
 Incremental model
 Prototype model
 Spiral model
 V — shaped model
SDLC models can be divided into three methods such as,
ï,§ Iterative
ï,§ Sequential
ï,§ Progressive
1.1.1Feasibility Study
In this step they give a high level view to the intend project and terminates its targets. By investigating on feasibility criteria the software developer or a leader of the project will get a very good plan for the further phases without wasting time, money and other resources. Feasibility study is basically derives into three sections and those are:-
1.1.2 Time feasibility
We can check that the given time to complete the project is enough or not. So in time feasibility it is verify whether the given period is sufficient to complete the project. If the given time is sufficient then the time feasibility is achieved.
E.g. — If customer wants to finish the project in two years and you need to check that can you complete the project within the given time duration.
1.1.3 Cost feasibility
Lots of money spends to develop software. Cost feasibility is making analysis on the cost spend for the project. So the project holders must decide the correct budget for the project. Otherwise there will not enough money to complete the project.
1.1.4 Scope feasibility
This is to ensure that the given cost to complete the project is enough or not. Customer request many requirements such as system should send email or SMS messages to the customer of the website as soon as they registered and upload pictures. So, in scope feasibility it is verified whether they can fulfil the need of the customer or not. If the development team verified that the above requirement of the customer can be successes then the scope feasibility is achieved.
If the development team can develop and submit the software within the given time and using the given budget with the customer requirements they can take the project. The document that make after the feasibility study is called Feasibility report.
1.2 Requirement gathering
The requirement phase translates the needs of the client into a formal document. Bringing the client and the supplier to an agreement on what the product will provide. The following are the requirement gathering technics that are available:-
 Research and site visits
 Observation
 Questionnaire
 Interviews
1.2.1 Research and site visits
Going through several researches, Research guides and visits the required web sites to gather information.
1.2.2 Observation
System analyst either participates in or watches a person perform activities to learn about the system.
1.2.3 Questionnaire
Questionnaire means a special resolve document that allows the specialist to collect information’s and opinion from responders.
Free format questionnaire
A questionnaire designed to offer the respondent greater latitude in the answer. A question is asked and the respond records the answer in the space provided after question.
Fixed format questionnaire
A questionnaire containing questions that are required choosing an answer from pre-defined offered responses.
1.3 Interviews
Unstructured interviews — An interview that is conducted with only a general gall or subject in mind and with few specific questions.
Structured interviews — An interview in which the interviewer has a specific set of questions to ask of the interviewer.
Open ended question — A question that allows the interviewee to respond in any way that seems appropriate.
Close ended question — A question that restricts answers to either specific choices or direct responses.
1.4 Designing
The designing process begins when the requirement document for the software to be developed is available. The design project for software system has two levels and those are:-
I. System design
II. Detail design
There are 2 specification of designing as,
 Logical designing
 Physical designing
There are different methods of designing which are different from each other.
1) Entity relationship diagram
2) Data flow diagram
3) Flow chart
4) Structure chart
5) Unified modelling language (UML) diagram
The information that should be included in the designing document is:-
ï,§ Principle data
ï,§ Function algorithms
ï,§ Basic programs
ï,§ Project specific information
The output of the designing process is “Designing report”
1.5 Coding
Coding is one of the most important stage in SDLC because real code of the software are create or written here. If the designing stage is done correctly a good coding can be produced by the developers. In these coding stage different programming language are used.
Example of programming languages are:-
• C++
• ORACLE
• APACHE
Different programming languages are used to do the coding according to the need of the project.
1.6 Testing
After the designing process the next step of SDLC is testing. Software testing verifies that the software meets the requirements. It involves the operation of a system or application under control conditions and evaluating the result. After coding was done the entire module or units are combined together and check for error using proper tools. Why error happens,
• Less time to complete the project
• Missed contact
• Programming error during coding phase
• Changing of customer need
The output of the testing procedure is “Test log” There are various kinds of testing techniques. Those are below.
Testing techniques:-
 Integration testing
 Integration incremental testing
 System testing
 Regression testing
 Acceptance testing
 Black box testing
 White box testing
 Unit testing
1.6.1 Integration testing
Integration testing is a software development activity which program units are compound and proved as groups in many ways. In this context, a unit is defined as the smallest testable part of an application. Integration testing can elicit problems inter program components before risk be happens in real world program execution.
1.6.2 Unit Testing
Unit testing is a stage of the software testing process where individual units of a software or system are tested. The reason is to corroborate that each unit of the software performs as designed.
1.6.3 Regression testing
The choosy retesting of a software system that has been customized to make sure that any errors have been fixed and that no other before working functions have failed as a result of the compensation and that recently added features have not created problems with previous versions of the software. This also referred as “Verification testing”.
1.6.4 Integration incremental testing
Integration incremental testing is a testing which first you test each unit of the software individually then continue testing by adding another unit to it then another. Its proper definition is “integration testing strategy in which you test subsystems in isolation, and then continue testing as you integrate more and more subsystems”.
1.6.5 Acceptance testing
An efficient test performed on a product before it is put on the market or delivered to the customer. The acceptance testing process is planned to replicate the aspired real life use of the product to make sure that what the customer receives is completely functional and meets their needs and expectations.
1.6.6 System testing
System testing is a step of the software testing process where complete, integrated software is tested. The purpose of this test is to evaluate the system’s compliance with the illustrated requirement.
1.6.7 Black box testing Black box testing is done by the system testers or quality assurance programmers. They test the quality of the software or the system before implement it. This is also known as behavioural testing. These testing can be functional or non-functional, however usually it is functional.
1.6.8 White box testing
White box testing is done by programmers. Through this test they test for the syntax error. The tester chooses inputs to exercise paths through the code and decides the suitable outputs. Programming knows how and the implementation knowledge is necessary. White box testing is beyond the user interface and into the reality of a system.
1.7 Maintenance
In maintenance stage you are basically maintaining the system that you have implemented. In this stage it changes, correction, addition, moves to a different computing platform and more. Typical function performs of maintenance part are:
o Identification and correction of previously existing errors, falls or failures which we undetected during both initial development and test.
o Modification to improve system performances without adding new performance capabilities.
E. g.:- Changes to account for system hardware enhancement
Importance of SDLC to the proposed system
With give the touch of SDLC to the proposed system the lots of people can achieve lots of things. Inside of those people there are designers, programmers, Developers and so on. This important because it helps with the validation, training and user ownership in the design phase of the project. And also it gives a web developer or programmer a plan to follow. By following the SDLC, the developer’s software will be more successful.
 
Task 2 — Developing a feasibility report
What is feasibility report?
The resolve of a feasibility study is to consider the task requirements and to determine whether it’s do anything. Request a useful and what to continue to see that, in a process that should last several tests. Each application must be made by SDLC. We cannot do anything without a plan. Developers often use to project feasibility studies. Feasibility study to be sure that we always have the problem that the customer should be accepted using the four main phases of a project is possible to measure. Feasibility uses four main phases to measure a proposal.
Introduction
The feasibility study see the possibility of designing the project with an important on categorizing the problem and try to answer to a main question such as can we carry on the project or not by checking the budget, time and customer requirements for this Company. So by having a good feasibility study it will help us to have a successful project. Feasibility study is an initial study of a project that helps the developer of the project to check whether to continue the project or not before spend time and money. It also help to analyse the amount of money needed to each phase and the time needed to each phase. So, feasibility study makes the project proceed successful and also help to understand the contests such as what the user in the market really need from the website. Feasibility study help to examine the tools needed to carry on a successful project. Feasibility study examines weather the time period required to complete the project is enough or not.
Purpose of feasibility report
The purpose of the feasibility study is to make a rough plan to the full project initially and examine possible alternative answer to a difficulty and suggest on the best alternative before the programme begins without any wastage of money and time. The feasibility study analysis on the main feasibility criteria such as time, cost and scope feasibility and the result gain by this verify or make decision to progress with the product to the customer on time because work is done to a schedule. The structure of the project is well defined. Danger and the advantages of the project are also defined. So, feasibility report is needed to continue the project without any problem project or not. So, in this report the amount of the money required to total project is verified so there will be no problem in shortage of budget at the middle of the project or at the end and making the project failure. The time required to the each phase is planned so, there will be no problem occurs in submitting the
Justification for the proposed system
After conducting the feasibility for the Smart Arcade Company I’m hoping to complete the project within six months period of time and we are hoping to give some important details to the company to use within five month period of time roughly. We are hoping to have about five employees with a team leader. The details of the new orders placed by the customers which are uploaded by the administrator will be not shown to the viewers as it passes the correct available date of the company uploaded by the administrator.
Feasibility study
1 .Time feasibility
2. Cost feasibility
In this section we identify the financial cost and benefits according to develop the system. Therefore from Economical feasibility we can decide whether the new system is useful to implement. In this section we have to show the benefits that we can earn from the proposed system. The estimated value is RS.160, 000 for 6 months. I will try my best to give the company a good service.
3. Scope feasibility
In feasibility study the scope feasibility was one of the important studies to be done at the beginning of the development process to carry on a project without failure. In scope feasibility expert verify whether they can achieve the company requirements.
The functioned that will be required by the customers are such as,
ï,§ details to the customer
ï,§ report of buying customers and the selling report of the company
ï,§ Easy and quick search engine
4. Technical feasibility
The technical features required to implement the product are mention in the technical feasibility. I’m using the latest technology using latest version of Visual Studio 2015. The technical feasibility is to make sure that the project feasibility within the limits of current technology.
Conclusion
With going through this complete feasibility report the development team will be able to get a clear idea about the requirements to implement a software to a get details of Customers ordering placements and its criteria such as time, cost, operational, technical and scope feasibility. So if someone read this carefully that person can get what are the importance of having feasibility report and what is the including of the feasibility report.
 
Task 3 — Developing a Systems Requirements Specification (SRS)

Task 5 – Quality Management
Introduction
Quality management is the process of ensuring that the company meets the customer’s expectations by providing them with goods and services that are consistent. In a manufacturing company this can entail providing goods that have little or no defects and in the service sector it may mean providing services that will enhance customer loyalty and hence customer retention. Quality management is a method for ensuring that all the activities necessary to design, develop and implement a product or service are effective and efficient with respect to the system and its performance, therefore uses quality assurance and control of processes as well as products to achieve more consistent quality. It is related to improving quality of goods and services in order to satisfy the customers’ ever changing needs.
Evaluate how user and systems requirements have been addressed
As mentioned in the 3rd Task of SRS the Quality of this Software will be long last without any bugs as because the software’s used to make this software is High Graded once. This won’t Crash the program in anytime in case if it happened, whenever they update their files there will be an Auto Backup to the Hard Drive. The process for the all defects will be done as follows;
Check sheets and Process Instructions
• Access process instructions and author check sheets directly from the control panel
• Fully combined with and driven from the Control Plans module
Control Plans
• Help ensure compliance with quality standards by creating and managing powerful and helpful, detailed process control plans with detailed inspection instructions and check sheets
• Specify sample frequency, control chart types and other quality-oriented data
• View and carry out control plan instructions and check sheets directly from the Control Panel and other interfaces
• Highly mixed with product specifications Is often a necessary element for quality standard compliance
