SOFTWARE AND SYSTEMS DEVELOPMENT 8.1 ANALYSIS STAGE
THE ANALYSIS STAGE
This crucial stage looks at what the current system is and does and what the requirements of the new system or change in the current system are. There is a lot of research that needs to be done to ensure the planned new system will integrate with current systems, will fit the purpose it is designed for and that it will meet the needs of the users. This stage is often broke up in too many different tasks, some of which are discussed below.
REQUIREMENTS ANALYSIS
SCENARIO: What is the problem the client is facing RATIONALE: Why and how will your product concept help solve the problem TECHNOLOGY STACK: What technology does the client have and what additional technology is needed. What software requirements might be needed and what does your client have. What languages will you write your program in, why are they suitable and what user interface is required by the client.
EXISTING SYSTEM REVIEW
The purpose of an existing systems review in the software development cycle is to evaluate and analyze the current systems, processes, and technologies in use by an organization or business. This review is carried out before starting a new software development project in order to gather information about the existing systems and identify any areas for improvement.
The existing systems review provides a comprehensive understanding of the current architecture, design, and data structure of the systems in use, which helps in identifying any limitations or constraints that may impact the design of the new software. It also helps to identify any areas of the existing systems that can be reused or integrated with the new software, which can help to reduce development time and cost.
In addition to technical considerations, the existing systems review also takes into account the business requirements and goals, as well as the user requirements and preferences. This information is used to guide the design and development of the new software, ensuring that it meets the specific needs and expectations of the organization or business.
Overall, the existing systems review is an important step in the software development cycle as it helps to ensure that the new software is designed and developed in a way that is aligned with the organization's goals, integrates smoothly with existing systems, and meets the needs of the users.
AVAILABLE OR COMPETING SOLUTIONS
Reviewing already available competing solutions is an important step in the software development process as it provides valuable insights into the market and helps to ensure that the new software is unique and meets the specific needs of the target audience.
Understanding the market: By reviewing competing solutions, developers can gain a better understanding of the market, including the current trends, technological advancements, and user expectations. This information can be used to identify opportunities for innovation and differentiation, and to ensure that the new software is relevant and competitive.
Identifying strengths and weaknesses: Reviewing competing solutions allows developers to identify the strengths and weaknesses of existing solutions, including any features that are missing or areas for improvement. This information can be used to inform the design of the new software and to ensure that it offers a better user experience.
Avoiding duplicated efforts: By reviewing competing solutions, developers can avoid duplicating efforts and reinventing the wheel. Instead, they can build upon the existing solutions and focus on creating something new and innovative.
Staying ahead of the competition: Reviewing competing solutions helps developers to stay ahead of the competition and to ensure that the new software is innovative and offers a unique value proposition. This can help to attract and retain customers and to establish a strong market position.
In summary, reviewing competing solutions is an important step in the software development process as it helps to inform the design and development of the new software, ensure that it is unique and relevant, and stay ahead of the competition.
FEASIBILITY STUDY
A feasibility study is a process of evaluating the viability of a proposed project or solution to determine whether it is worth pursuing. The purpose of a feasibility study is to analyze and assess the potential benefits, drawbacks, and risks associated with a project, and to determine whether it is technically, financially, and operationally feasible.
A feasibility study typically involves several steps, including:
Defining the problem or opportunity: The first step in a feasibility study is to clearly define the problem or opportunity that the proposed project is intended to address.
Gathering information: The next step is to gather information about the problem or opportunity, including any relevant data, market research, and expert opinions.
Analyzing the data: The information gathered is then analyzed to determine the potential benefits, drawbacks, and risks associated with the proposed project. This includes a technical analysis to determine whether the project is technically feasible, a financial analysis to determine whether it is financially viable, and an operational analysis to determine whether it can be successfully integrated into the existing operations.
Evaluating alternatives: The feasibility study may also evaluate alternative solutions to determine which is the best option.
Making a recommendation: Based on the results of the feasibility study, a recommendation is made as to whether the proposed project should proceed or not. If the feasibility study concludes that the project is not feasible, the project may be adjusted or abandoned. If the project is deemed feasible, the next steps can be taken to move forward with its development and implementation.
A feasibility study is an important step in the software development process as it helps to ensure that resources are not wasted on projects that are unlikely to be successful. It provides valuable insights into the potential benefits, drawbacks, and risks of a proposed project, and helps to make informed decisions about whether to proceed with its development.
