COMPUTER SCIENCE Which of the following code segments correctly creates a four-element array and initializes it so that each element stores its index? For example, the element stored at index 2 is 2. I int[] a={0, 1, 2, 3}; II int[] a={1, 2, 3, 4}; III int[] a=new int[4]; for (int i=0; i<4; i++) a[i]=i; a. I only, b. I and II, c. II and III, d. I and III, e. I, II, and III. Verified answer

Rapid Development Which software activities are inter-leaved during rapid software development? 1. Specification How are the systems developed? System is developed as a series of versions with stakeholders involved in version evaluation What advanced the development of agile methods? Dissatisfaction with the overheads involved in software design methods of the 1980s and 1990s led to the creation of agile methods What is the aim of agile methods? The aim of agile methods is to reduce overheads in the software process and to be able to respond quickly to changing requirements without excessive rework Agile Manifesto We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value: *- Individuals and interactions over processes and tools - Working software over comprehensive documentation - Customer collaboration over contract negotiation - Responding to change over following a plan* What do Agile Methods focus on? Incremental development methods that focus on: 1. Rapid development List the principles of agile methods 1. Customer Involvement Customer Involvement - involved throughout the development process. - provide and prioritize new system requirements - evaluate the iterations of the system. What is plan-driven development? A plan-driven approach to software engineering is based around separate development stages with the outputs to be produced at each of these stages planned in advance. - Iterations occur within the activities What is agile development? - Specification, design, implementation and testing are inter-leaved - Outputs from the development process are decided through a process of negotiation during the software development process. What are some problems with agile methods? 1. It can be difficult to keep the interest of customers who are involved in the process. 2. Team members may be unsuited to the intense involvement that characterizes agile methods. 3. Prioritizing changes can be difficult where there are multiple stakeholders. 4. Maintaining simplicity requires extra work. 5. Contracts may be a problem as with other approaches to iterative development. Key issues with maintainability when using agile methods - Uncertainty if these systems are maintainable since formal documentation has been reduced significantly. - Can agile methods be used effectively for evolving a system in response to customer change requests? Factors in determining which software process to use 1. Type of software being developed Two popular agile methods 1. XP Consideration for Scaling Agile Methods 1. Agile methods have proved to be successful for small and medium sized projects that can be developed by a small co-located team. 2. Success of these methods comes because of improved communications. What are Large Systems? They are usually collections of separate, communicating systems, where separate teams develop each system. Large System Development Teams are working in different places and sometimes different time zones. They are brownfield systems - they include and interact with a number of existing systems. They don't really lend themselves to flexibility and incremental development. A significant fraction of the development is concerned with system configuration rather than original code development. They have a long procurement and development time. It is difficult to maintain coherent teams who know about the system. What is scaling out? Concerned with how agile methods can be introduced across a large organization with many years of software development experience. What is Scaling Up? Concerned with using agile methods for developing large software systems that cannot be developed by a small team. Fundamentals of Agility 1. Frequent planning Scaling up to large systems It is not possible to focus only on the code of the system. You need to do more upfront design and system documents. Cross-team communication mechanisms have to be designed and used. Continuous integration, where the whole system is built every time any developer checks in a change, is impossible. Scaling out to large companies Project Managers who do not have experience may be reluctant to accept the risk of a new approach. Standards, quality procedures and bureaucracy nature of large organizations are usually incompatible with agile methods. Agile Methods seem to work best when team members have a relatively high skill level. What is Agile methodology quizlet?Agile development refers to a group of software development methodologies that are based on iterative development, where requirements and solutions evolve through collaboration between self-organizing cross functional teams.
What are the advantages of agile methodology quizlet?Agile favours benefits and innovation through collaboration with a particular focus on customer satisfaction, quality, teamwork and effective management.
What are some methodologies that can be used for agile project management quizlet?The most popular agile methodologies include Extreme Programming (XP), Scrum, Crystal, Dynamic Systems Development Method (DSDM), Lean Development, and Feature-Driven Development (FDD).
What is a methodology used by systems analysts?The most common system analysis techniques are: Block diagram (system analysis) Fault tree analysis (system analysis) Event tree analysis.
