Explanation of Solution
System development methodologies:
System development methodology can Standardize across entire enterprise using the below three methodologies.
- Spiral methodology
- Agile methodology
- RUP methodology
Spiral methodology:
This methodology is a combination of iterative development and sequential linear development methodology.
This methodology consists of set of framework activities. Every framework activity denotes one unit of spiral path. The most importance phase in this methodology is risk analysis.
The phases in agile methodology are planning, design, construct, evaluation.
Phases in the spiral methodology:
- Planning:
This phase initially begin with the collection of business requirements. This phase contains the understanding of system requirements by common conversation between the customer and the analyst. The product is planned at the final spiral process.
- Design:
This phase contains the architectural and logical design of the module. It also contains the final design in the following spiral.
- Construct:
This phase develops the final software product at each spiral process.
- Evaluation and risk analysis:
Risk analysis contains recognizing, evaluating, and examining methodological feasibility such as plan slippage and price overrun.
Agile methodology:
This methodology targets the customer satisfaction by delivering the software components quickly and continuously to the customer. This process carried over by an iterative process, which uses minimum requirements.
The phases in agile methodology are planning, requirement analysis, designing, building and testing.
Rational Unified Process (RUP) Methodology:
This method targets the customer needs by delivering the high quality product. This methodology improves the team productivity.
Gates of RUP methodology:
This methodology used for separating the software development into four gates. Each gate contains the repetition of the software process in development.
This methodology develops the product in numerous stages based on response from the stockholders. The four gates is are inception, elaboration, construction, transition
- Inception:
The idea of proposed system identified in this phase. This phase verifies if each stockholder shared the idea of given proposed system and required resources.
- Elaboration:
The developer explains the architecture and needed resources of the given system.
- Construction:
The development of the given product completed in this phase. Moreover, the product design and source code are finished in this phase.
- Transition:
The modifications are done in this phase. Here any modifications or updates are prepared based on user feedback.
Comparison to traditional waterfall approach:
Compare spiral methodology with waterfall methodology:

- You have been selected to participate on the systems investigation team for a new system in your area of the business. How can you contribute to the success of the effort? How might you use critical success factors to identify important system requirements?arrow_forwardThe objective of system planning is to align specific system projects or applications with the organization's overall strategic objectives. In reality, the company's business plan serves as the foundation for the systems plan, since it outlines where the organization wants to go and how it intends to go there.Explain why recognizing and addressing an issue early in the system development lifecycle is much less costly than later in the process.arrow_forwardSystems Development Life Cycle: Objectives and Requirements Source: http://www.benderrbt.com/Bender-SDLC.pdf A systems development lifecycle (SDLC) has three primary objectives: ensure that high quality systems are delivered, provide strong management controls over the projects, and maximise the productivity of the systems staff. In order to meet these objectives, the SDLC has many specific requirements it must meet, including: being able to support projects and systems of various scopes and types, supporting all of the technical activities, supporting all of the management activities, being highly usable, and providing guidance on how to install it. The management activities include: setting priorities, defining objectives, project tracking and status reporting, change control, risk assessment, step wise commitment, cost/benefit analysis, user interaction, managing vendors, post implementation reviews, and quality assurance reviews. In order to meet all of the SDLC's objectives and…arrow_forward
- Explore the concept of a Systems Development Life Cycle (SDLC) and its role in shaping various system model approaches. Provide examples of SDLC phases in specific projects.arrow_forwardSubject: System analysis and design Question 1-a) You as a system analyst need to provide solutions with brief explanation for the following scenario. Bata company wants to develop a system so that the head office can take update from all its branches spread throughout the country. Before analyze and design the system you want to take requirement from them. What question structure will you choose for this company and why you choose this method? Write six questions for the interview according to your chosen structure. Question 1-b)Now design context level and level zero data flow diagram for the proposed system after collecting requirement from Bata company.arrow_forwardThe System Development Life Cycle (SDLC) is a structured approach used in IT to ensure the consistent development of high-quality systems. It facilitates efficient resource management, risk mitigation, and clear stakeholder communication throughout the development process. By emphasizing thorough documentation, user-centered design, and continuous feedback, the SDLC ensures the system's relevance and effectiveness over time. Discuss the impact AI might have on this process and how it might streamline this process.arrow_forward
- For an Order Management System (an order management is a software system used in various industries to automate order entry and processing), Identify some subsystems within the system. Also draw diagram/s to show the communication links between the subsystems. 2.Which Software Metaphor you think suits your project most? Support choice with at least 3 reasons. 3.Identify and elaborate any 3 approaches to software reuse that can be implemented to enhance the quality and accelerate the development.arrow_forwardDevelopment: As CIO of a large insurance company, you need to manage the development of several mission critical systems. You have a choice as to whether to use agile techniques or the systems development life cycle. What are the advantages and disadvantages of each approach and which one do you choose?arrow_forwardPart (a). One of the essential steps of the system development life cycle is preparing feasibility studies, including technical, economic, legal, operational and schedules feasibility. We have discussed these feasibilities in the interactive tutorials in details. Discuss these feasibilities briefly. And elaborate cost-benefit analysis under economic feasibility. [4 Marks. Word Limit: Up to 200 words] Part (b). The system experts perform the design and implementation phases of the system development life cycle. However, the accountant’s role in these phases cannot be ignored. Comment on the statement. [3 Marks. Word Limit: Up to 150 words]arrow_forward
- Cindy Winslow liked her new job as lead systems analyst at Yorktown Industries. She was pleased that her development team completed the new human resources system ahead of schedule and under budget. Cindy looked forward to receiving the post-implementation evaluation because she was confident that both the system and the development team would receive high marks from users and manager. After the system operated for one month, Cindy received a call from her supervisor, Ted Haines. Ted told her that she would have to handle the evaluation, even though she headed the development effort. Cindy told Ted that she did not feel comfortable evaluating her own team’s work. She explained that someone who was not involved in its development should do an independent evaluation. Ted responded that he had full confidence in Cindy’s ability to be objective. He explained that no one else was available and he needed the evaluation quickly so he could move forward with the next stage in the corporate…arrow_forwardThis Question related to the subject Database Keeping in view the concept of Software Development Life Cycle (SDLC), you are advised to extract/describe the following information: a) Identify strategic planning factors? b) Describe the functional system requirement specifications? c) Select the appropriate language / tool for the development of the given below system and reason for the selection of language? d) Write down the suitable steps for the development of working Prototype?
