...System Development Life Cycles (SDLC) * * * * * Tutorial 3 in a series of 6 - Overview of Software Engineering Principles 3 The system development life cycle (SDLC) follows a project through from the initial idea to the point where it is a functional system. It is a core part of the methodology that is used when defining a project. Life cycles fall into a number of different categories, iterative being the most common but they also include waterfall, spiral and chaos models. Common methodologies include Structured Systems Analysis and Design Method (SSADM) and Microsoft Solutions Framework (MSF). Each step in a systems lifecycle can be broken down into many smaller sub-steps or processes. Each stage follows logically after the previous, but it is an oversimplification to say that one stage is a distinct step after another. It is important to understand that the system lifecycle is iterative as well as the stages involved along the way. Different methodologies will have different variations of this lifecycle model. A common iterative lifecycle is show in the diagram below and each stage is described after the diagram. Initial Idea All projects must start with an initial idea. Usually this consists of a brief definition on what is the project all about, what is its purpose and what the project aims to accomplish. How will the success of the project be measured? Feasibility Study Expanding on the Initial Idea, the Feasibility Study involves...

...The system planning and selection stage addresses the needs or opportunities that can be achieved by an IT proposal. During this step, we must consider all current priorities that would be affected and how they should be handled. Before any system planning is done, a feasibility study should be conducted to determine if creating a new or improved system is a viable solution. This will help to determine the costs, benefits, resource requirements, and specific user needs required for completion. The development process can only continue once management approves of the recommendations from the feasibility study. Systems analysis The goal of the systems analysis is to determine where the problem is in an attempt to fix it by breaking down the system. During this phase, we determine requirements and structure them according to their interrelationships, eliminating redundancies. The end result being well defined requirements that are a good fit based on the organization’s needs and budget. System design In the system design phase, functions and operations are described. It can be broken down into two steps. Logical design (blueprint) is described independently of any computer platform and is then transformed into technology-specific details known as physical design. Design elements are intended to describe the system in great detail to developers so that they can deliver the system with minimal additional input. System Implementation & Operation During this final phase...

...Systems Analysis and Design (SAD) is an exciting, active field in which analysts continually learn new techniques and approaches to develop systems more effectively and efficiently. In business, SAD refers to the process of examining a business situation with the intent of improving it through better procedures and methods. System analysis and design relates to shaping organizations, improving performance and achieving objectives for profitability and growth. The emphasis is on systems in action, the relationships among subsystems and their contribution to meeting a common goal. Systems development can generally be thought of as having two major components: Systems analysis and Systems design. System design is the process of planning a new business system or one to replace or complement an existing system. System analysis is the process of gathering and interpreting facts, diagnosing problems, and using the information to recommend improvements to the system. This is the job of the systems analyst. A system is orderly grouping of interdependent components linked together according to a plan to achieve a specific objective. Its main characteristic are organization, interaction, interdependence, integration and a central objective. To construct a system, system analyst must consider its elements- input and output, processors, control, feedback, and environment. Systems are classified as physical or abstract, open or closed, and man-made information systems. A system may be schematic...

What are the issues and technical alternatives to be considered when developing international information systems? 10 References. 13 Section A. Executive Summary This document aims to explain the system design and hardware blueprint of the XO-4 laptop. While the capabilities of the XO-4 are similar to a regular laptop, it was designed for elementary school children. The primary goal of the hardware design is low-power operation, and for extensive use in developing countries or rural areas where access to classrooms are not always available. 1. What are the capabilities of the XO laptop (especially the latest version, XO-4)? How well-suited is this machine for developing countries? According to wiki.laptop, (2013) the XO-4 are different to other laptops as all components except the keyboard and touchpad are located behind the LCD panel and is called the Core Module. Furthermore the keyboard encoder, touch pad module, keyboard matrix, and battery are combined in a separate Input Module that is connected to the core module by means of two cables in the laptop hinge (wiki.laptop, 2013). The core processing system used in XO-4 is the Marvell PXA2128, which integrates multiple ARM processor...

...M-tech’s Espresso after some short interview with some related people. Blake also gave four main advantages of the proposed information system as followed: Rapid response, Quaility control, Preventive maintenance, and Reporting. This system allow housekeepers to report problems as soon as possible without waiting so that it can reduce the chance of “slippage through the cracks” if the housekeeper forgot to communicate the problem. This system also can avoid the same problem occurred again and the manager can reward the employees according to their performance based on the data which showed by the system. While Blake got another account, so, his classmate Jack took over this case. After one month and a half, Blake was told that his solution was failed. It was useless and it just wasted money. When he came back to RH, he found that the Espresso was sitting in a corner, nobody cares about it, and every employee thought the older manual system was better than the new one. When Blake prepared to find a solution to make the new system work, a sentence gave him a tinge of hope: “Focus on the information system design, not the technology investment”. 2. Explain why they are in the current situation (mistakes and the people at fault) and what should have been done instead. The employee in RH was not familiar with the new information system Espresso, and due to Blake’s shift to other account, there was...

...Questions #7 IT 193 - Systems Analysis & Design Chapter 7: Development Strategies 1. Describe the trend that views software as a service rather than a product. What effect has this trend had on software acquisition options? * The concept of software as a service is redefining the way that companies develop and deploy their information systems. People in various companies expect traditional packaged applications to be replaced by web-based services that remove the responsibility for installation, maintenance, and upgrades from a company’s in-house staff. https://www.coursehero.com/file/8417844/Chapter7-ReviewQuestions/ 2. Explain the difference between horizontal application software and vertical application software. * A software package that can be used by many different types of organizations is called a horizontal application. An accounting package is a good example of a horizontal application because it can be utilized by many different businesses. In contrast, a software package developed to handle information requirements for a specific type of business is called a vertical application. https://www.coursehero.com/file/8417844/Chapter7-ReviewQuestions/ 3.

...Part A 1. A. Joe Costello- Joe Costello seemed to be a good, trusting man whose trust was taken for granted. Not only did employees feel they could steal from his business, but he also accused them of stealing from his home on three separate occasions. Because of how wrong he was done, Joe wanted nothing more than to see Hsu, and his cohorts at Avant! pay for what they did. He was determined to see justice. While some industry mates chose to ignore what had happened and advised him to turn the other cheek, it was something that would not allow Joe to let up, and rightfully so. He also seems to be somewhat naïve. This opinion is founded on the ground that he did not give any ultimatum for the employees who refused to sign a document that make them contractually obligated to “respect Cadence’s trade secrets” (Bygraves, 2011). While it was awful convenient that Costello was so insistent on taking down a fierce competitor, the fact remains that its foundation rests upon stolen information. The thing that adds insult to injury for Costello is that this was all done at the hands of a former employee that he worked alongside for years. He seems to be equally outraged by everyone who seems to be nonchalant about Avant!’s behavior. B. Gerry Hsu- Gerry was the VP of Cadence before resigning to join the Avant! startup. He was preceded in resignation by four other employees three years earlier. It is apparent that Gerry had ill intentions from the time he left Cadence, because of advising...

...project is to investigate the fundamental problem that plagues all software development: the gap between the intentions of the designer, as described (often only minimally) in design and specification documents, and the behaviour of the delivered system, as realized in the code. We are developing new languages, tools and methods to address this problem. Our work also incorporates independent analyses of designs and code. By applying our design analyses, we can be sure that the design as described has the intended consequences the designer had in mind. By applying our code analyses, we can eliminate flaws that do not depend on comparison to a design, and can discover properties that can be later fed into a conformance analysis. Rather than pursuing a single, narrow research approach, we have tried to explore the problem from many angles. We consider how a codebase may be analyzed in the presence of some design models; how it might be analyzed if there is no explicit design documentation; and how minimal design properties expressed as code annotations might be exploited. We have developed static analyses that require no execution of the code but can simulate the effect of all possible executions, and dynamic analyses that require a test suite but can produce more accurate results. Some of our static analyses are conservative, and can guarantee properties of all executions; others are sound in their error reports, so that no false alarms are given. Some of our tools exploit test cases;...
