Methodologies of Inofrmation Systems

Introduction In this report I will outline what is the different methodologies used to develop computer based information systems. I will elaborate on the methodologies of the SDLC, SSADM, JAD and RAD. I will be referencing to various books and journals from the Institute’s library to academically illustrate my report through a number of credible sources. At the conclusion of this report the reader should have a considerable amount of knowledge on the methodologies of an information system and when…

Case Study_ System Development

System development is a process in which programmers with organization contribution write codes to solve a problem that face the organization system or automate a procedure. There are three major systems development techniques that been used to solve systems’ problems. The system development techniques are SDLC (Systems Development Life Cycle), JAD (Joint Application Development), and RAD (Rapid Application Development). SDLC provides tools for controlling details within large development projects that solve structured problems. JAD enables the identification, definition, and implementation…

Business Information Systems

1. What is a decision? When does a person have to make a decision? A decision is a conclusion or resolution reached after a thought out consideration of variables in a problem. When more than one possible action is involved in solving a problem, a decision must be made. 2. Calculating a complex trajectory of a spaceship to Mars is a structured problem, whereas diagnosing the cause of a rash on a person’s skin is often unstructured. How so? A…

Rad Rapid Application Diagram

This chapter discusses the methodology, the data gathering techniques, and the scope and delimitation of the study. This will serve as the guide to the proponents on how they will conduct the study systematically in order to fulfill the study’s objectives. Software Development and Methodology The Rapid Application Development (RAD) approach would be used to develop the system because of time constraints in the development schedule. RAD is a linear sequential software development process model that emphasized on extremely short…

Alumni Tracking System

An issue tracking system (also ITS, trouble ticket system, support ticket or incident ticket system) is a computer software package that manages and maintains lists of issues, as needed by an organization. Issue tracking systems are commonly used in an organization’s customer support call center to create, update, and resolve reported customer issues, or even issues reported by that organization’s other employees. An issue tracking system often also contains a knowledge base containing information on each customer, resolutions to common…

Methodology Spiral Model

As per the name, spiral model is a software development methodology that is arranged in a spiral shape. It was proposed by Barry Boehm and is mostly used to handle high risk and also large projects. The spiral model uses iterations, meaning similar steps that are repeated until the needs are satisfied. This methodology is suitable when requirements are not clear to the software developers. Prototypes are made in this methodology and given to the users to be tested to…

What Are the Pros and Cons of the Technique

Pros of Waterfall Method The waterfall model, as described above, offers numerous advantages for software developers. First, the staged development cycle enforces discipline: every phase has a defined start and end point, and progress can be conclusively identified by both vendor and client. The emphasis on requirements and design before writing a single line of code ensures minimal wastage of time and effort and reduces the risk of schedule slippage, or of customer expectations not being met. Getting the requirements…

Extreme Programming (xp)

Agile projects are similar to traditional projects. “You still must define and initiate the project, plan for the project, execute the plan, and monitor and control the results” (“ccspace.com,” 2011). How these steps are accomplished is different and therefore, the Agile project manager must adapt his approach. One agile software engineering method is Extreme Programming or XP. XP is a collection of values, principles and practices designed to rapidly create highquality software that provides the maximum value for the customer…
