Describe the RADSoftware Process Model with Disadvantages

RAD Model Rapid Application Development (RAD) is an incremental software development process model which is a “high-speed” adaptation of the linear sequential model in which rapid development is achieved by using component-based construction. If requirements are well understood and project scope is constrained, the RAD process enables a development team to create a “fully functional … Read more

Describe Evolutionary Software Process Model

Evolutionary Software Process Mode: Evolutionary software models are iterative. They are characterized in manner that enables the software engineers to develop increasingly more complete version of a software. That is, initially a rapid version of the product is being developed and then the product is developed to more accurate version with the help of the … Read more

Describe the Prototyping Software Process Model with Disadvantages

Prototyping Model Often, a customer defines a set of general objectives for software but does not identify detailed input, processing, or output requirements. In other cases, the developer may be unsure of the efficiency of an algorithm, the adaptability of an operating system, or the form that human/machine interaction should take. In these, and many … Read more

Describe the Linear Sequential Software Process Model with Disadvantages

Linear Sequential Model/Waterfall Model/Classic Life Cycle The linear sequential model, sometimes called the classic life cycle or the waterfall model, suggests a systematic, sequential approach to software development that begins at the system level and progresses through communication, planning, modeling, construction and deployment. The following given figure illustrates the linear sequential model for software engineering. … Read more

Describe the problem solving loop.

Problem Solving Loop : All software development can be characterized as a problem solving loop in which four distinct stages are encountered: status quo, problem definition, technical development, and solution integration.             Status quo represents the current state of affairs, problem definition identifies the specific problem to be solved, technical development … Read more

What is software process model?

Software Process Model :  To solve actual problems in an industry setting, a software engineer or a team of engineers must incorporate a development strategy that encompasses the process, methods, and tools layers and the generic phases.  This strategy is often referred to as a process model. A process model for software engineering is chosen … Read more

What is CMMI ? Describe the levels of CMMI.

CMMI (The Capability Maturity Model Integration):  The Software Engineering Institute (SEI) has developed a comprehensive model predicated on a set of software engineering capabilities that should be present as organizations reach different  levels of process maturity. To determine an organization’s current state of process maturity the CMMI uses two ways, (i) as a continuous model … Read more

What is software process and software process framework ? Explain.

Software Process:  Process defines a framework for a set of Key Process Areas (KPAs) that must be established for effective delivery of software engineering technology. This establishes the context in which technical methods are applied, work products such as models, documents, data, reports, forms, etc. are produced, milestones are established, quality is ensured, and change … Read more

What are the Umbrella Activities in Software Engineering?

umbrella-activities-in-software-engineering-onlineclassnotes.com

Software engineering is a collection of co-related steps. These steps are presented or accessed in different approaches in different software process models. Umbrella activities are a set of steps or procedure that the software engineering team follows to maintain the progress, quality, change and risks of the overall development tasks. These steps of umbrella activities will evolve through the phases of generic view of software development.

Describe the three phases of the generic view of software engineering.

The work associated with software engineering can be categorized into three generic phases, regardless of application area, project size, or complexity. Following flowchart encompasses the phases. Three Phases of the Generic View of Software Engineering: 01. Definition Phase:  The definition phase focuses on “what”. That is, during definition, the software engineer attempts to identify what … Read more
