Concurrent engineering is an approach to product development in which multiple phases of the product development process are carried out simultaneously instead of sequentially. The main objective of concurrent engineering is to improve product quality and shorten development time by overlapping the different product life cycle stages. Concurrent engineering uses tools like development models to maximize the product development process. Concurrent engineering is a holistic approach to product development in which all stakeholders work together from the beginning to the end of the project.
The concurrent model is a methodology in which multiple phases of the software development process are performed simultaneously (concurrently). The main goal of the concurrent development model is to produce a final product that meets the customer's requirements while minimizing the overall development time and cost. In other words, it is a way to streamline the software development process by simultaneously working on various aspects of the project.
Concurrent Process Model In Software Engineering Advantages And Disadvantages
The waterfall model is a sequential design process in which each phase of the software development process must be completed sequentially before moving on to the next phase. This model moves linearly from the earliest stages of development (requirements gathering) to the final stages (deployment and maintenance). It is called the waterfall model because each phase is completed one at a time, and progress flows in a linear, downward fashion similar to how water moves through a waterfall. Winston W. Royce first popularized the model in 1970.
The method is popular for its simplicity and its easy-to-use approach. It is a popular choice for small projects that do not require many changes during development. Some common advantages of this model include:
The prototype model is a type of concurrent engineering in which a working model of the final product is created early in the development process. This prototype is then used to gather feedback from the customer and make changes to the product before it is completed. Prototype models are typically used where the level of human-computer interaction is high. The prototypes can test user interfaces and gather feedback on how the user interacts with the product.
The main advantage of using the prototype model is that it allows customer feedback to be incorporated into the final product. This can result in a better product that meets the customer's needs and expectations. Other advantages of the prototype model include:
The spiral model is a type of concurrent engineering in which the product is developed in a series of spirals. There are many cycles in the spiral model, each representing a different development phase. The spiral model is a combination of both the waterfall model and the prototype model. It combines the advantages of both models and offers a more flexible approach to software development. Barry Boehm first introduced the model in 1986.
The spiral model is often used with projects expected to last for months to years, require regular updates, and are complex and dynamic. Often, software updates or change requests use the spiral model. It is often used on projects with high risks because it allows for changes to be made throughout the development process. Some example projects that might use the spiral model include aircraft design, spacecraft design, and military applications.
Concurrent models are development models in which multiple processes or phases of the development process are carried out simultaneously. Concurrent models are essential in software engineering because they provide a more systematic, efficient, and flexible approach to developing software products. There are many different types of concurrent models. Three common types are the waterfall model, the prototype model, and the spiral model. The waterfall model is the most traditional and linear of the three models. In the waterfall model, each phase of the development process must be completed before moving on to the next phase. Winston W. Royce introduced it in 1970.
The prototype model is more flexible and allows for changes to be made to the product throughout the development process. It is centered around creating prototypes and refining them until the final product is achieved. Prototype models are often used when the user and system interaction is very high. Advantages of the prototype model include that it allows for user feedback to be incorporated early on and can help reduce development costs. One potential disadvantage of the prototype model is that early prototypes can have low reliability. The spiral model is a combination of both the waterfall and prototype models. It offers a more flexible approach to software development and is well suited for use on large, complex, and dynamic projects. Barry Boehm introduced the spiral model in 1986. Spiral models are often used for a piece of software that needs software updates. Each of these models has different advantages and disadvantages. Selecting the best concurrent model for a particular project depends on the nature of the project and the preferences of the software development team.
There are several elements of concurrent engineering. Three common elements are simultaneous development, customer feedback, and iterations. Together, these elements help to create a development process that allows a certain degree of malleability and refinement while remaining systematic and efficient.
There are several advantages of concurrent models. Some of these advantages include allowing for the incorporation of user feedback early on in the development process, helping to reduce problems later on in the development process, and providing a more efficient and flexible approach to developing software products.
Concurrent models are often utilized in software engineering as they provide a more systematic, efficient, and flexible approach to developing software products. When deciding which model to use, the project's specifics should be taken into account, as well as the preferences of the software development team.
Agile methodology is a practice that helps continuous iteration of development and testing in the software development process. In this model, development and testing activities are concurrent, unlike the Waterfall model. This process allows more communication between customers, developers, managers, and testers.
Incremental Model is a process of software development where requirements are broken down into multiple standalone modules of software development cycle. Incremental development is done in steps from analysis design, implementation, testing/verification, maintenance.
An iterative life cycle model does not start with a full specification of requirements. In this model, the development begins by specifying and implementing just part of the software, which is then reviewed in order to identify further requirements. Moreover, in iterative model, the iterative process starts with a simple implementation of a small set of the software requirements, which iteratively enhances the evolving versions until the complete system is implemented and ready to be deployed. Each release of Iterative Model is developed in a specific and fixed time period, which is called iteration.
Furthermore, this iteration focuses on a certain set of requirements. Each cycle ends with a usable system i.e., a particular iteration results in an executable release. Iterative Model allows accessing previous phases, in which the changes are made accordingly. The final output of the product is revived at the end of the Software Development Life Cycle (SDLC). Typically iterative development is used in conjunction with incremental development, in which a longer software development cycle is split into smaller segments that are built upon each other. Hence, iterative model is used in following scenarios:
The process of Iterative Model is cyclic, unlike the more traditional models that focus on a rigorous step-by-step process of development. In this process, once the initial planning is complete, a handful of phases are repeated again and again, with the completion of each cycle incrementally improving and iterating on the software. Other phases of the iterative model are described below:
It is extremely necessary to know the advantages of the Iterative model, before implementing it in the Software Development Life Cycle (SDLC). The biggest advantage of this model is that, it is implemented during the earlier stages of software development process, which allows developers and testers to find functional or design related flaws as early as possible, which further allows them to take corrective measures in a limited budget. Other benefits or advantages of this model are:
Even though, iterative model is extremely beneficial, there are few drawbacks and disadvantages attached to it, such as, each phase of an iteration is rigid with no overlaps. Also, system architecture or design issues may arise because not all requirements are gathered in the beginning of the entire life cycle. Other disadvantages of iterative model are:
A software is developed with several different techniques and methodologies. It requires tools, models, and other external elements to achieve successful completion. Iterative model, is one such development technique that allows small scale software development effortlessly. It is one of the key practises in Agile Development methodologies, in which steps are repeated as the project progresses with requirements.
Iterative model iterates Requirements, Design, Build and test phases again and again for each requirement and builds up a system iteratively till it is completely built. Moreover, iterative model can accommodate changes in requirements, which are very common in most of the projects. It also provides an opportunity to identify and build any major requirement or design flaws throughout the process because of its iterative nature. 2ff7e9595c
