Your job A systems analyst shall be responsible for studying the problems and needsof an organization and for determining how people, methods, and information technologycan best be combined to bring about improvements in the organization. A systems analyst helps system users and other business managers define their requirementsfor new or enhanced information services. As such a systems analyst is an agent of change and innovation.
Systems Analyst Skills • Technical– Must understand the technical environment, technical foundation, and technical solution. • Business – Must understand how IT can be applied to business situations. • Analytical – Must be problem solvers. • Interpersonal – Need to communicate effectively. • Management – Need to manage people and to manage pressure and risks. • Ethical - Must deal fairly, honestly, and ethically with other project members, managers, and systems users.
SDLC: systems development life cycle • The SDLC usually incorporates the following general purpose problem solving steps: • Planning – identify the scope and boundary of the problem and plan the development goals and strategy • Analysis – study and analyze the problems, causes, and effects. Then identify and analyze the requirements that must be fulfilled by any successful solution • Design – design and construct or purchase the solution • Implementation – implement the solution • Support – analyze the implemented solution, refine the design, and implement improvements to the solution. This may lead to cycling back to previous steps.
Planning – “why build the system” • Identify business value • Analyze technical, economic and organizational feasibility • Identify tasks and estimate time required • Staff the project • Control and direct the project • System request • Feasibility study • Work Plan • Staffing Plan • Gantt charts, CASE tools, risk assessment
Analysis – “who, what, where, when” Analyze the problem, perform benchmarking, reengineering Gather business requirements – interviews, questionnaires, etc. Specify the requirements – use cases Model the processes – data flow diagrams Model the data – entity relationship diagrams Deliverable: the system proposal
Design – “how will the system work” Decide who will do the construction Architecture design Interface design Database and file design Program design Deliverable: System specification
Implementation – system delivery • Construction • Programming • Testing • Installation • Conversion (direct, parallel, phased) • Training • Change management • Support

The Feasibility of a New System • An important starting point • Is there a technical solution that will work? • Should we build it? Does it make economic sense? • Will we be able to use it?
Technical Feasibility Familiarity with the application Familiarity with the technology Project size Can it be built and function as envisioned using appropriate technology?
Economic Feasibility:Expected Value • Costs • usually come first • easier to quantify at outset of project • Benefits • look carefully for tangible, monetary items • convertible • space, productivity, risk of loss • nonconvertible • morale, ‘showcase’
Organizational Feasibility • Can the organization handle the new system? • Stakeholders • winners and losers • Champions • operational, functional, financial • Objectives • what is possible? • what is expected?
Feasibility Analysis A dynamic document – should be revisited and updated regularly In addition to technical, economic, and organizational feasibility, might also consider schedule feasibility, etc. Establishing benchmarks for costs and benefits is important - you can’t manage what you can’t measure
For Next Week • Prepare to come to the tutorials after the lecture • We’ll set up teams for assignments then • Read Chapters 1 and 2 • Try to find the most interesting and/or important development in Information Technology in the week • try Surfing a bit: CNN MSNBC etc...
