LO2 Explain the importance of a feasibility study. Assignment Brief and Guidance: Assignment scenario Tune Source is a company headquartered in southern California. Tune Source is the brainchild of three entrepreneurs with ties to the music industry: John Margolis, Megan Taylor, and Phil Cooper. Originally, John and Phil partnered to open a number of brick-and-mortar stores in southern California specialising in hard-to-find and classic jazz, rock, country, and folk recordings. Megan soon was invited to join the partnership because of her contacts and knowledge of classical music. Tune Source quickly became known as the place to go to find rare audio recordings. Annual sales last year were $ million with annual growth at about 3%–5% per year. Tune Source currently has a website that enables customers to search for and purchase CDs. This site was initially developed by an Internet consulting firm and is hosted by a prominent local Internet Service Provider (ISP) in Los Angeles. The IT department at Tune Source has become experienced with Internet technology as it has worked with the ISP to maintain the site. System Request Project Sponsor: Carly Edwards, Assistant Vice President, Marketing. Business Need: This project has been initiated to increase sales by creating the capability of selling digital music downloads to customers through kiosks in our stores, and over the Internet using our website. Business Requirements: Using the Web or in-store kiosks, customers will be able to search for and purchase digital music downloads. The specific functionality that the system should have includes the following: ● Search for music in our digital music archive. ● Listen to music samples.

Choose one that you think suitable for the project and explain why. ● 350 - 500 words for each model. ● Explanation: 400 – 600 words. Discuss the suitability of each of the SDLC models for the project. For each model, specify whether it is most, moderately or least suitable. ● Word limit: 800 - 1000 words. Discuss the merits of applying the waterfall model to a large software development project. ● Word limit: 800 – 1200 words.
2. Identify some risks and discuss an approach to manage them. You will have the present what is Risk Management process with clear illustrations and explanations. Then you will create a Risk Management Matrix to assess and manage risks of Tune Source project. ● Word limit: 600 – 1000 words.

Task 2 – Feasibility study

1. Discuss the purpose of conducting a feasibility study for the project. ● Word limit: 400 – 600 words.
2. Discuss how the three feasibility criteria (technical, economic, organizational) are applied to the project. Discuss whether the project is feasible. Discuss alternative technical solutions using the alternative matrix. ● Word limit: 1200 – 1500 words.
3. Explain the components of a feasibility report. Discussion economic feasibility study on Tune Source project (NPV, Cashflow, Break-Even Point) ● Word limit 350 – 500 words.

Discussion organizational feasibility study on Tune Source project ● Word limit 350 – 500 words.

4. Assess the impact of each feasibility criterion on a software investigation. Discussion and represent as feasibility alternatives matrix for Tune Source project ● Word limit: 500 – 700 words.

I Introduce:

Software Development Life

Cycle (SDLC) is the process of

determining how an information

system can support business

needs, designing

the system, building it, and

delivering it to users. It is a

framework that has a set of

tasks to be performed at each

stage in the software

development process. It is a

process of giving a complete

idea of the development, design

and maintenance of a software

project by

ensuring that all functionality

along with user requirements,

goals and final objectives are

resolved together. With SDLC,

the quality of the

software project and the overall

software development process

is enhanced. If you've taken a

coding class or have

programmed yourself,

this might sound simple.

However, in the real world, it is

clearly about how SDLC is

important.

Describe two iterative

and two sequential

software lifecycle

models

In detail, the SDLC

methodology focuses on the

following six phases of software

development, popular SDLC

models include the

waterfall model, spiral model,

and Agile model

(ALEXANDRA ALTVATER,

2020).

II Describe two iterative and two sequential software lifecycle models

1. Describe the following SDLC

SDLC or the Software Development Life Cycle is a process that produces software with the

highest quality and lowest cost in the shortest time possible. SDLC provides a well-structured

flow of phases that help an organization to quickly produce high-quality software which is well-

tested and ready for production use.

In detail, the SDLC methodology focuses on the following six phases of software development,

popular SDLC models include the waterfall model, spiral model, and Agile model

(ALEXANDRA ALTVATER, 2020).

There are six phases of SLDC:

Requirement analysis

At this stage comprises receiving input from various stakeholders, including customers,

salespeople, industry experts, and programmers. Determine the present system's strengths

and flaws in order to improve it.

Planning

At this stage of the SDLC, the

team assesses the cost and

resources required to

accomplish the analyzed

requirements. It also

discusses the dangers and

suggests sub-plans for

minimizing them (Altvater,

2020).

At this stage of the SDLC, the team assesses the cost and resources required to

accomplish the analyzed requirements. It also discusses the dangers and suggests sub-

plans for minimizing them.

Software design such as architectural design

The software specifications are

turned into a design plan known

Actual development begins in

this stage. Each developer must

strictly stick to the agreed-upon

strategy. Also, ensure that

developers have a proper coding

style and process norms in place

Actual development begins in this stage. Each developer must strictly stick to the agreed-

upon strategy. Also, ensure that developers have a proper coding style and process norms

in place.

Testing

At this stage, the developers check and detect the errors that arise in the software and fix

them so that the software has the best quality before it comes to customers.

Deployment

The purpose of this step is to

deploy the software to the

production environment so that

users can begin utilizing the

product.

Furthermore, this permits any

last flaws to be identified before

the product is released

The purpose of this step is to deploy the software to the production environment so that

users can begin utilizing the product. Furthermore, this permits any last flaws tobe

identified before the product is released.

SDLC is important because it provides an effective framework and method to develop software

applications. It helps in effectively planning before starting the actual development. SDLC

allows developers to analyze the requirements. It helps in reducing unnecessary costs during

development.

a.Waterfall

Waterfall Model is a sequential model that divides software development into pre-defined

phases. Each phase must be completed before the next phase can begin with no overlap

between the phases. Each phase is designed for performing specific activity during the

SDLC phase. It was introduced in 1970 by Winston Royce.
