    Study Notes

    Systems Analysis and Design

    • The Systems Development Life Cycle (SDLC) is a process for determining how an IS supports business needs, designing, building, and delivering it to users.
    • The systems analyst is the key person in the SDLC, responsible for analyzing the business situation, identifying improvement opportunities, and designing the IS.
    • Systems analysts must have technical, business, analytical, interpersonal, management, and ethical skills.

    Systems Analyst Roles

    • Business analysts focus on IS issues surrounding the system.
    • Systems analysts focus on the business issues surrounding the system.
    • Infrastructure analysts focus on technical issues.
    • Change management analysts focus on the people and management issues surrounding system installation.
    • Project managers ensure that the project is completed on time and within budget, and that the system delivers the expected value to the organization.

    The Systems Development Life Cycle (SDLC)

    • The SDLC is composed of four phases: Planning, Analysis, Design, and Implementation.
    • Each phase includes steps that rely on techniques to produce deliverables, which are specific documents that explain elements of the system.

    Planning

    • The planning phase determines why an IS should be built and how the project team will build it.
    • Project initiation identifies the system’s business value.
    • Project Management involves creating a work plan, staffing the project, and using techniques to control and manage the project throughout the SDLC.

    Analysis

    • The analysis phase addresses who will use the system, what it will do, where and when it will be used.
    • The project team investigates current systems, identifies improvement opportunities, and develops a concept for the new system.
    • The analysis phase consists of three steps: analysis strategy, requirements gathering, and system proposal.

    Design

    • The design phase determines how the system will operate, including hardware, software, network infrastructure, user interface, forms, reports, programs, databases, and files.
    • The design phase includes four steps: design strategy, architecture design, database and file specifications, and program design.

    Implementation

    • During implementation, the system is developed or purchased and installed.
    • This phase is often the longest and most expensive part of the process.
    • The implementation phase consists of three steps: system construction, installation, and support plan.

    Project Identification and Initiation

    • A project is identified when someone in the organization recognizes a business need for a system.
    • New IS projects may emerge from Business Process Management (BPM).

    Business Process Management (BPM)

    • BPM is a methodology for continuous improvement of end-to-end business processes.
    • BPM involves defining and mapping process steps, creating ways to improve value-adding steps, eliminating or consolidating non-value-adding steps, and adjusting electronic workflows to match improved processes.
    • Business Process Automation (BPA) uses technology to complement or substitute manual processes.
    • Business Process Improvement (BPI) creates new or redesigned processes to improve workflows, and/or utilizes new technologies for process restructuring.
    • Business Process Reengineering (BPR) fundamentally changes how an organization operates.

    Project Sponsor

    • The project sponsor has a vested interest in the system’s success and works throughout the SDLC to ensure the project’s proper direction.
    • The project sponsor is the primary point of contact for the project team.
    • The size or scope of the project determines the kind of sponsor involved.
    • The project sponsor provides insights for determining the business value expected from the system.

    System Request

    • The system request is a document that describes the business reasons for building a system and its expected value.
    • The project sponsor completes this form as part of a formal system selection process.
    • The business requirements define the system’s necessary capabilities.
    • The business value describes the organization’s expected benefits from the system.
    • The document includes a catchall category for special issue considerations.
    • The completed system request is submitted to the approval committee for consideration.

    Feasibility Analysis

    • Feasibility analysis helps the organization decide whether to proceed with a project.
    • It identifies project risks that need management if the project is approved.
    • Most feasibility analyses include techniques to assess technical, economic, and organizational feasibility.

    Technical Feasibility

    • Technical feasibility assesses the extent to which the system can be successfully designed, developed, and installed by the IT group.
    • It is a technical risk analysis that determines if the system can be built.
    • Risks to successful project completion should be considered.

    Economic Feasibility

    • Economic feasibility, also called a cost-benefit analysis, identifies the costs and benefits associated with a system.
    • It addresses whether to build the system.
    • Cash flow, both inflows and outflows, are estimated over some future period.
    • Common methods for evaluating project worth include Return on Investment (ROI) and Break-Even Point (BEP).

    Discounted Cash Flow Technique

    • This technique compares the present value of cash inflows and outflows for the project in today's dollar terms.
    • Net present value (NPV): the difference between the total present value of benefits and the total present value of costs.
    • Steps to conduct an economic feasibility analysis include identifying costs and benefits, assigning values, determining the cash flow, and calculating profitability.
