The Systems Development Life Cycle

1. (B) An analysis of proposed system feasibility and a logical system design are part of which of the following SDLC phase? a. Construction phase b. Definition phase c. Implementation phase d. System-building phase

Technical feasibility examines the company’s ability to successfully construct the proposed system. The project team must analyze whether the organization has the appropriate knowledge and skills needed for completion of the system. Hardware, software, and other system requirements must be addressed and the team must determine if the company is technologically inclined to proceed with the project with the current technology.

Feasibility study: - address two main questions, which are, Is the projects feasible and can it be justified? At the stage of feasibility study the implications and costs of development are not known.

Technical feasibility: Checks the organizations current technology. Asking the question “will it handle the suggested new system?” If the current technology does not, this would mean that the company would need to upgrade software or hardware or both to make it technically feasible. If the current technology can handle the new system, then it would be technically feasible without any technical upgrades.

Firstly, a feasibility study is carried out of the current system. It is necessary to investigate before spending too much time and money on the development. It will normally consider the actual problem and the proposed solution from different points of view.

The systems development life cycle is a conceptual model which is used in project management that is explains the stages one by one development project, from starting to complete the application.

System development can generally be thought of having two major components: systems analysis and systems design. In System Analysis more emphasis is given to understanding the details of an existing system or a proposed one and then deciding whether the proposed system is desirable or not and whether the existing system needs improvements. Thus, system analysis is the process of investigating a system, identifying problems, and using the information to recommend improvements to the system. System design is the process of planning a new business system or one to replace or complement an existing system.

Baderman Island will have to go through a specifications and metrics process to be able to implement successfully the new enterprise technology. The company will go through the systems development life cycle (SDLC) when implementing the new technology. “SDLC is the process of developing information systems through investigation, analysis, design, implementation and maintenance. SDLC is also known as information systems development or application development. SDLC is a systems approach to problem solving and is made up of several phases, each comprised of multiple steps” (Webopedia, 2008, para.2). The company will go through many SDLC associated activities, such as, planning, analysis, design, development, testing, implementation and maintenance.

System development life cycle is a process use for the period of development system. SDLC contains four main steps those are analysis, planning, design and implementation during the analysis steps of dataflow diagram used to process the model of a system. A consistency of the context diagram to lower dataflow diagram is very important for easy process model of a system, manual consistency check from context to lower level data flow diagram using a checklist is time intense process

Though many people interchange system engineering models and software engineering life cycle models, they are defined as two different approaches to software development. System engineering is the technical and technical management process that results in delivered products and systems that exhibit the best balance of cost and performance. As the program progresses from one phase to the next one, so does the system engineering process. It deals with the overall management of engineering project during their life cycle. Its main focus is knowing what the clients and end users wants and needs are satisfied and developing just that all the way through the system’s entire life cycle. Whereas, on the other hand, software engineering focuses on the quality of the product or system, how cost effective it is, is it done within the time-constraints given, whether it is easy to maintain and enhance, and does it work as the requirements defined. Its main focus is on delivering a product that meets the requirement specifications. There are so many models to choose from, as it all depends on what the project needs and entails. Depending on the requirements, allows for the choice of what mode to use.

The same analysis applies when launching a new product. Part of your feasibility study must then focus on understanding what the customers are looking for and whether your proposed idea answers these needs. You should also compare the proposed product with the existing products or services and focus on the advantages, as well as disadvantages, you might have.

Operational feasibility focuses on how the proposed system will help to improve the identified problems in the current system. This includes the benefits of introducing the proposed system to the employees. This will also help to figure out whether the proposed system is going to provide any positive

The decision to implement any new project or program must be based on a thorough

The Feasibility study is an analysis of possible alternative solutions to a problem and a recommendation on the best alternative. It can decide whether a process be carried out by a new system more efficiently than the existing one.
