Task 01

Explain the stages of the software development life cycle and explain the benefits and drawbacks of the staged life cycle model for the proposed system

Software engineers are using Software Development Life Cycle (SDLC) because this method is suitable tocreate software’s to the customers without errors. This process explains the step by step how to develop software. There are five stages for software development life cycle. Those are

Feasibility Study Report and Requirement Gathering

Feasibility Study is divided in to three they are Time Feasibility, and Scope Feasibility

Time Feasibility

Feasibility

Study

Cost Feasibility

Scope Feasibility

Time Feasibility – Time Feasibility means the given time is enough or not to create the software. Eg : If the given time is 12 months this feasibility checks the given time is enough to finish the project

Cost Feasibility – Cost Feasibility means the given budget is enough or not to complete the software project.

Eg: If customer offer 2 lakhs for the project this feasibility checks the given money is enough for complete the project

Scope feasibility – Scope feasibility is about accomplishing the customers requirements. If the customer is satisfied with the created software that means the scope feasibility is achieved.

These three Feasibilities are very important when developing softwares. That’s why they called as the triple constant of the project, If one of this is not achieved it is called as a failed project

Requirement Gathering is also very important when creating softwares because with this we can get a good idea about what are the things that customer needs with the software. Thereof we can achieve scope feasibility. Requirement gathering can be done by different ways like observations, interviews questioners, and researched site visit.

Observations

Interviews

Requirement Gathering

Questioners

Researched site visit

Observation

This is an efficient way to gather requirements. When a employee is reviewing a client senior agent would be watching the observation. But there are few Gide lines to follow those are

The Observer must inform the observed that he’s under observation.

The observer mustn’t interrupt any individual.

The Observer must not make any assumptions.

Questioners

It is a good way to collect informations and opinions from respondents. These questioners are admissible as

free format questioners / unstructured questioners

Or

Fixed format questioners / Structured questioners by special document.

Free format questioners / unstructured questioners

In this type of questioners respondent can answer whatever his or her think about the question

Example: Are you satisfy with the current system? ……………………………………………… ………………………………………………………………………………………………………

Fixed format questioners / Structured questioners

When respondent answering this type of questions he or she cans only underline or tike the given answer.

Example : Are you satisfy with the current system ?

YES NO

Interviews

Interviews are very good method for collect information directly from the customer.

Type of interviews

Unstructured interviews

In the Unstructured interviews interweaver will conducted with only a general goal, interviwer has no specific setup questions.

Structured interviews

Structured interviews means interviewer will ask specific setup questions from the interwivee

Open ended questions

When answering to open ended questions, questions should full and meaningful

Close ended questions

A question that restricts the answer to either specific choices or short direct responses.

After the feasibility study, analysis have to make a report called Feasibility study report and when the requirements are gathered and they are completed system analysis also have to make a document called SRS (Software Requirement Specification)

Designing

After the requirement gathered you can start designing. the designing should be done according to the requirements. Design is a blueprint of the software. Design can be done using entity relationship diagrams, data flow diagrams, Flow charts, structure charts, unified modeling language (UML) diagrams, Decision tree and Decision tables.

When the design information are done it should be insert to a document called Design document

Coding

After you done requirement gathered and designing you can start coding your programme. When you coding the important thing is code should consist with the design. When coding they use high ended languages like C++ or Java

When you have done the coding you have to make a document called coding document

Testing

After you have done the coding section you can start the testing. Testing is a very important part because in this section programmer will test the system again and again to find an errors and he or she will make sure the system is done according to the requirements. If programmer found an error he or she will refer it to fix the problems. The subsets of the domain used in the testing process is called the data set

When we testing a system we use different types of testing techniques to present a first class project. Those are

Unit Testing method

Integration Testing method

Incremental, Integration Testing method

System Testing method

Functional Testing method

Acceptance Testing method

Regression Testing method

Unit Testing method

In this testing method the software will divided in to parts and test divided parts individually. This is the simplest method.

Part 2

Part 1

Part 4

Part 3

Integration Testing method

In this testing method more than one part is testing at the same time. For an example software devided in to four parts and takes 1 and 2 parts at the same time and test them. Then takes part 2 and part 3 the same time. Diagram will explain more. We use this method to make sure that the combined parts of the software is able function together correctly and effectively

Part 2

Maintainers

If the system has done according to the requirements and if there are no errors found in system , it will concentrate to maintainers. in the maintainers you have suppose to make a document called the user manual. User manual will explain how to use the software that we crated and how it is working. And also this user manual document describes how to handle the other documents that we made before.

When creating software we need to choose an applicable path. The success of the software is depends on the path that we choose. There are various paths to choose those are called as Software Development Process Models

Waterfall Model

Incremental Model

Evolutionary Model (Prototype Model)

Spiral Model

V-Model

Incremental Life Cycle Model

This project is lager but easy if the software Development Company chooses a correct life cycle model to develop it. I suggest incremental life cycle model to build the related system. Because they can analyze the risk of the project easily in this model and they can again gather requirements after each stage done. Software Development Company can also finish the software within given budget and the give time. Therefore they can achieve triple constrains and content the client

Advantages of Incremental Life cycle Model

Provide some feedback allowing later

Can understand mistakes and minimize the at the next cycle

Can go to a new cycle and stables requirements

It is more responsive to user needs than waterfall model

Risk is low than waterfall model

accurate results are possible

Task 02

How does the Spiral Model overcome the limitations of the Waterfall Cycle Model and the Incremental model? Explain by referring to the proposed system

Waterfall Model

Disadvantages of the Waterfall Model

Risk is high because acceptance testing can be failed

Working product is not available until late in the project

Progresses can success not observable

Advantages of spiral model

Can identify risk again and again, that helps to avoid mistakes and errors.

When we using a spiral modal we can search customer needs than other models.

When to use spiral model

When the project is medium and high risk

When the customer wants to change his requirement

Task 03

Prepare a Feasibility report to the proposed System and discuss its components. The report should consist of Introduction, purpose of the feasibility report, project description, system functionality, Feasibility study(Time, Cost, Scope, Technical, Economic) conclusion and referencing

Task 04

Assess the impact of Time, Cost and Scope feasibility criteria on systems investigation for the recommended solution.

Impact of Feasibility Report

Software development is not an easy work. Designing, coding and maintenance parts are the hardest parts in the life cycles. When developing softwares there are three feasibilities to achieve they are time, cost and scope, these three are called as a triple constrains. These triple constrains are useful for fulfill customer requirements. If customer or the developer not satisfy with one of this constrain the result of the software is failure. Before develop the software developer should show a blueprint of the software to client

Impact of Time Feasibility

To achieve this feasibility developer should complete the project within the given time. If developer failed to submit the software within the agreed time period it can be the end of that development. Sometimes clients will close the agreement before the software finish. If it happened developer will face to a bigger problem. So the achieving time feasibility is very important

Impact of Cost Feasibility

As mentioned software developing is not an easy task. Developer and client must come to a concurrence before finish the software. Both of them have to agree to the budget that spending for the software. Designing, coding and maintenance parts are the hardest parts when developing. Therefore software development companies should pay a good salary for the designers, coordinators and other workers who work on the relevant project.

Impact of Scope Feasibility

Software development is a complex process. Developer should go through the customer ideas and requirements. If customer not satisfied with the software lots of problems may occur. The project should not exceed the agreed budget and project should done within the given time period. If developer achieve this feasibilities scope feasibility is achieve auto.

Task 05

Investigate the system requirements and prepare a sample SRS for the proposed system. The document should consists of Introduction, purpose, scope, overall description, Hardware requirements, Software requirements, Functional requirements, non-functional requirements conclusion and referencing.

Problem Statement

In the modern world there are lots of companies that publish their names by the websites. They attract customers by using user-friendly interfaces, colourful backgrounds, advertising and many other ways. Auto Lanka privet limited was a leading company in Sri Lanka. But today they are facing lots of problems with their manual system. Because sellers need to come to the location of the auto Lanka privet limited headquarters and should give their selling vehicle informations. Likewise buyers need to come to the auto Lanka headquarters and search the vehicle by their requirements through books. If there is no vehicle with the required functions they need to give their telephone number to the headquarters. This process is outdated process. It wastes lots of time and sometimes telephone lines are not working properly.

Future recommendations

Security

In the present world we can’t trust outsiders. Some of them are tiring to seal data from the website and damage to them. They are called hackers and crackers. Even FBI website in United States Of America has been attacked by the hackers some times. Our New security system is perfect but I recommend improving the system firewall also

Store backup

The new system is coming with the data backing up feature as ana new feature. All the data are backing up to the particular computer. I recommend to keep this computer away from the Auto Lanka PVT LTD headquarters.

Advertising

Auto Lanka Online vehicle information system will be promoted on the online social network websites like facebook and twitter. Lots of people around the globe using these social networks today. Therefore it will be a good publicity for Auto Lanka Online vehicle information system website.

Mobile based web pages

Today everyone are using mobile phones even Gread 5 children are using them. So I recommend introducing a mobile webpage also

Conclusion

Having successfully completed my assignment and I able to get an in-depth knowledge about System Analysis and design. Ms Ruwanthis guidance’s are always helped me when doing assignment.
