• What are the 6 System Analyst Skills?

  Technical, Business, Analytical, Interpersonal, Management, and Ethical
• The systems analyst is a key person in the systems development life cycle (SDLC), who analyzes the business situation, identifies opportunities for improvements, and designs an information system (IS) to implement the improvements.
• The systems analyst plays a crucial role in IS development projects, working closely with all project team members to ensure the team develops the right system in an effective way.
• Systems analysts must understand how to apply technology in order to solve problems.
• Systems analysts may serve as change agents who identify organizational improvements needed, design systems to implement those changes, and train and motivate others to use the systems.
• Technical skills are essential for systems analysts, who must understand the technical environment, technical foundation, and technical solution.
• Business skills are also important for systems analysts, who must understand how IT can be applied to business situations.
• Analytical skills are crucial for systems analysts, who must be problem solvers.
• Interpersonal skills are necessary for systems analysts, who need to communicate effectively.
• The planning phase has two steps: during project initiation, the system’s business value to the organization is identified, and during project management, the project manager creates a work plan, staffs the project, and puts techniques in place to help the project team control and direct the project through the entire SDLC.
• During this phase the project team investigates any current system(s), identifies improvement opportunities, and develops a concept for the new system.
• Planning is the fundamental process of understanding why an information system should be built, and determining how the project team will go about building it.
• The analysis phase has three steps: analysis strategy, requirements gathering, and system proposal.
• The design phase decides how the system will operate, in terms of the hardware, software, and network infrastructure; the user interface, forms, and reports that will be used; and the specific programs, databases, and files that will be needed.
• The analysis phase answers the questions of who will use the system, what the system will do, and where and when it will be used.
• During the implementation phase, the system is either developed or purchased (in the case of packaged software) and installed.
• This phase is usually the longest and most expensive part of the process.
• The design phase has four steps: design strategy, architecture design, database and file specifications, and program design.
• The implementation phase has three steps: system construction, installation, and support plan.
• Management skills are essential for systems analysts, who need to manage people and to manage pressure and risks.
• Ethical skills are mandatory for systems analysts, who must deal fairly, honestly, and ethically with other project members, managers, and systems users.
• The Systems Analyst is the key person in the development of information systems.
• Identify costs and benefits into four categories: development costs, operational costs, tangible benefits, and intangibles.
• There are many organizational factors that can have an impact on the project, and seasoned developers know that organizational feasibility can be the most difficult feasibility dimension to assess.
• The Systems Development Lifecycle consists of four stages: Planning, Analysis, Design, and Implementation.
• Assign specific dollar values to the costs and benefits.
• A second way to assess the organizational feasibility is to conduct stakeholder analysis.
