Advantages of using systems analysis and design techniques in approaching computerized information s

System analysis and design is used to solve internal problems, improve efficiency and expand opportunities, and it has a direct impact on the bottom line of a business. Therefore, evaluating the advantages is a worthwhile undertaking for business managers and owners.

Louis Jia-Ching Lin Introduction When developing information systems, most organizations use a standard of steps called the systems development lifecycle SDLC at the common methodology for systems development. SDLC includes phases such as planning, analysis, design, implementation, and maintenance.

At the heart of systems development, analysis and design are the second and third phases of SDLC. The analysis phase usually requires a careful study of the current system, which continues two sub phases: Requirements determination process usually involves a careful study of the current manual and computerized systems that may be replaced or improved within the project.

Analysis study process usually involves analysts to study the structural requirements according to the components interrelationships and eliminate redundancies. In the design phase, analysts design all aspects of the system, provide physical specifics on the system from input and output screens to reports, databases, and computer processes.

The traditional waterfall approach focuses on compartmentalizing project into several phases. The agile approach focuses on self-adaptive processes with an emphasis on individual talents. The object-oriented approach focuses on combining data and processes into objects and shares the iterative development approach of the agile method.

These approaches all have different advantages and disadvantages in a way that they could be used to fit and optimize different kinds of projects. The activities of one phase must be completed before moving to the next phase. At the completion of each activity or phase, a milestone has been reached and a document is produced to be approved by the stakeholders before moving to the next activity or phase; painstaking amounts of documentation and signoffs through each part of the development cycle is required.

Unlike the waterfall development methodology, agile forgoes the documentation but is initially difficult to adapt by adding many new facets to the development model that confuse people.

Fowler believes that each talented individual bring something unique to the development team and disagrees with the application of engineering principles that viewed people as interchangeable units.

In another article published by Ambler, he summarized a few key lessons learned when doing internet based development via agile methods, these lessons are: The process used to develop the software is expected to be refined and improved over time.

Improvements are done through a review process associated with the compilation of iterations. Agile methodologies are not for every project. Fowler recommends an agile or adaptive process if your project involves: It combines data and processes methods into objects.

Within an information system, objects could be customers, suppliers, contracts, and rental agreements. A set of diagrams or models is used to represent various views and functionality of the system and is commonly known as Unified Modeling Language UML.

The OO approach later becomes known as the unified process when these models are used along with a particular method of systems development. Unified process is an iterative and incremental approach to systems development.

Objects are grouped into classes to share structural and behavioral characteristics. OOAD also incorporates the use of inheritance; it allows the creation of new classes that share the characteristics of existing classes.

Similar to the agile methodologies, the object-oriented approach to systems development is similar in the way of iterative development approach. The aim, in essence, is to transform the use cases into analysis model to realize the associated goals.

In Hsueh's study, such analysis model is built through six steps incrementally, and his research team examined these steps by use case description to identify possible participating objects based on some heuristics. To proceed into the design phase, object oriented design involves a transformation process that transforms real-world concepts into a software model that provides solution model.

The transformation process is to be achieved by taking the following design issues into consideration: Therefore, these models very significantly from one development to another, some variability in the analysis models' content and structure is unavoidable.

For the unified process model, all phases of the SDLC are visited on to the developers satisfy the requirements in each increment.Aug 13,  · Advantages of system analysis and desing techniques for computerized information systems for business??
