It is a known fact that software development is a task that involves several complex and time consuming activities, which are combined together to create and design a software that is unique and different from its counterparts, as well as has exceptional features and quality. Moreover, before initiating the process of software development, the team of developers, testers, managers, and other stakeholders connected to the project, go through various stages of planning, designing, programming, and more. It is only after achieving success at each of these stages that the process of software development is initiated. These various stages of Software Development Life Cycle (SDLC) are extremely significant and carry a lot of importance.
Software engineers put in their great efforts to plan the whole development process of the project and ensure that no step is overlooked or considered unnecessary. Similarly, software designing too is a very significant stage of Software Development Life Cycle (SDLC) and is treated with utmost care and importance. Software engineers, before starting the development and testing process, design a basic structure of the software, which determines what techniques, methodologies, tools and more will be used to complete the development process. Furthermore, it also determines the types of tests that will be executed on the software. Hence, here is a discussion on software design and its strategies to help you understand its significance in Software Development Life Cycle (SDLC).
The first step in Software Development Life Cycle (SDLC), Software Design, is a process of implementing software solutions to one or more sets of problems. It transforms users and clients requirements into some suitable form, which helps programmer in coding and implementation. Software design usually involves problem solving and planning a software solution. This includes both low level component and algorithm design, as well as a high level architecture design. Moreover, software design moves the concentration from problem domain to solution drama. It tries to specify how to fulfil the requirements mentioned in Software Requirement Specifications (SRS).
Also, for assessing user requirements Software Requirement Specification (SRS) document is created, whereas for coding and implementation, there is a need of more specific and detailed requirements in software terms. The output of this process can directly be used into implementation in programming languages. Software design is both a process and model, wherein the former is a sequence of steps that enables the designer to describe all aspects of the software for building.
Software Design Strategy is a discipline that helps firms in deciding what to make, why to make it and how to innovate contextually, both immediately and over the long term. This process involves strategic design and interplay between design and business strategy. The software design strategy is mainly about organising design activities during the course of design. The organisation of design activities, be it planned or ad-hoc reflects a designer’s approach to creating a design. During the process of software development it is common that a software designer thinks about a list of design issues and tasks that need to be discussed and addressed as well as are just to be done in the ad-hoc way. Furthermore, design strategy can assist a designer in resolving several common problems such as:
To implement software design, software engineers use a variety of strategies that help them define their respective tasks and assists them with the designing process. The way these design strategies are intermixed and used can influence the outcome and the effectiveness of the final design. Moreover, these strategies may not be required every time, but they are immensely helpful in getting expected results and in mitigating the risks of any course of action. With the help of these strategies one can design a proper plan of software development and ensure that all the demands, requirements and request of the clients are taken care of. Therefore, here are few of these strategies used by software engineers for designing accurate as well as bug free software product.
Software Development Life Cycle (SDLC) is a culmination of numerous activities, each of which play a significant role in developing a product that has exceptional functionality, scalability, performance, quality and more. To achieve great success in creating a perfect software product, one needs to follow each and every stage and step of Software Development Life Cycle (SDLC), which will not only assist a software engineer in developing, testing, programming, and designing the product, but will also allow them to validate whether the software is being developed as per the demands of the client or the user. Software design is one such important step of SDLC, which helps in planning the structure as well as the process of development. From deciding the team efforts, testing techniques, and designing strategies to tools and other important factors affecting the process of software development, all takes place in this stage. Software designing also ensures that the requirements of the client are taken care of and are implemented in the software properly. Hence, it is with the assistance of software design that one can ensure that the whole process goes on smoothly and as per the decided plan.
