Course: INFO-6056-23 W Deliverable: Individual Assignment #1 Systems Development Foundations Due Date: Oct 7 th , 2023, Professor: Shrijy Atodaria Student Name: Onadebi Student No: __24354255_____ Problem Description 1. What is the role of System Analyst in System Development? What are skills required to become a System Analyst? Answer: The role of a system Analyst is that of a problem solver. The System Analyst studies the problems and needs of an organization to determine the best approach of improving an organization using Information technology, People and Methods. They also help system users and managers define their requirements for novelty or enhancing existing information systems. The skills required to become a System Analyst are: 1) Analytical skills, 2) Technical skills, 3) Managerial skills and 4) Interpersonal skills. 2. Explain reuse and its role in software development. Describe in short four approaches of reuse. Answer: Reuse in software development is the activity of creating modular code of components that can be used multiple times in the same or across different projects. Reuse in software development has several roles including some highlighted below: 1. Efficiency: The time for software projects development is reduced because components do not have to be created from scratch again but can be reused. 2. Code would be Consistent in behavior and structure across projects. 3. It leads to Cost reduction because less codes needs to be written from scratch. 4. It also simplifies maintenance, as one single codebase source can be modified, and changes easily updated across multiple projects. 5. It also plays a role in allowing for Innovation, as it saves development time for creative solutions instead of repetitive coding.

Four approaches of Reuse include : 1 Ad hoc Reuse: This refers to a situation where individuals are given freedom to write their own reusable code components/assets, but may hardly (if any) be rewarded for creating such assets. 2 Facilitated Reuse: This is the kind of Reuse where an organization makes available to the Developers tools, techniques and resources that enable development and sharing of reusable assets. However, the organization does not impose or require that the practice of Reuse be enforced, though encourages the practice. 3 Managed Reuse: This approach refers to the situation in which an organization mandates the development, sharing, adoption and reuse of code assets. The organization enforces policies and processes for ensuring that code Reuse is practiced, quality is ensured, and results measured. 4 Designed Reuse: This approach mandates and focuses heavily on effective, measurable code reuse, such that as much as 90% of software components may be reused across different software applications. This approach ensures and mandates that from the development stage, the developer should have as much as possible, the mindset of building code components for reusability. This is the most expensive approach, and this is so, because building reusable code takes expert level skill, time, focused planning, and rigorous testing which all add up to the cost of implementation using this approach. 3. Describe in short what Tangible Benefits & Intangible Benefits is. Also describe in short, the categories included in both. Answer: Tangible benefits are items or systems benefits that are quantifiable and can be measured in monetary value, with certainty. Some examples include reduced cost and higher profit margin. The categories included in Tangible benefits are: • Cost reduction and avoidance: This refers to monetary expenses’ reduction and/or avoidance. • Error reduction: This is a measurable decrease in system defects or bugs. • Increased speed of activity: This is efficiency gain in terms of quickly completing tasks or processes more quickly. • Increased flexibility: This allows for a system to incorporate new features or changes without extensive redevelopment, reducing measurable time and cost. • Improvement of management planning and control: This refers to measurable advantages gained by enhanced organizational plans, monitoring and management of its resources, projects, and operations. • Opening of new markets and increasing sales opportunities: This can be quantified in terms of the cash inflow brought about by sales in new markets.
