Study Notes

IT Application Planning and Justification

  • Organizations analyze application needs, justifying purchases based on goals, costs, and benefits.
  • An application portfolio prioritizes existing and potential IT applications.
  • IT planning starts with the organizational strategic plan, outlining mission, goals, and steps to achieve them.
  • The IT strategic plan is aligned with the organizational plan, defines an IT architecture, and efficiently allocates resources.
  • The IT steering committee links corporate strategy, approves resource allocation, and sets measures for the MIS function.
  • The IS operational plan details specific projects for the IS department and functional areas, including mission, environment, objectives, constraints, portfolio, resource allocation and management.

Evaluating and Justifying IT Investment

  • Cost-benefit analysis compares the costs and benefits of IT investments.
  • Calculating IT investment costs involves allocating fixed costs across projects and considering long-term maintenance and improvement expenses.
  • Evaluating benefits is often subjective and difficult to quantify, particularly intangible ones.
  • Companies may pilot new technologies to assess functionality and consumer acceptance.
  • Cost-benefit analysis methods include NPV, ROI, break-even analysis, and business case development.

Strategies for Acquiring IT Applications

  • Purchasing pre-written software is cost-effective and time-saving. Careful consideration of features is needed to avoid obsolescence.
  • Customizing pre-written software is flexible but can be complex, demanding thorough planning.
  • Leasing applications saves both time and money. The 80/20 rule suggests adapting business processes to leverage software that meets 80% of needs.
  • Application service providers (ASPs) or Software-as-a-Service (SaaS) vendors host applications, eliminating installation and maintenance costs.
  • Open-source software offers a flexible alternative via licenses.
  • Outsourcing to external contractors can provide access to experts. Offshoring, particularly to India and China, may offer lower costs but presents communication risks.
  • Continuous development steadily adds new code to a project.
  • Custom development offers better fit to specific requirements.

Traditional Systems Development Life Cycle (SDLC)

  • The SDLC is a structured framework for large-scale IT projects.
  • Six processes define the SDLC: investigation, analysis, design, programming, implementation, and operation/maintenance.
  • Systems investigation uses feasibility studies (technical, economic, and behavioral) to evaluate solutions.
  • Systems analysis gathers information on the existing system for defining system requirements.
  • Systems design specifies system outputs, inputs, processing, user interfaces and hardware/software specifications.
    • Approved design specifications are "frozen" to prevent scope creep.
  • Programming translates design specifications into code.
  • Testing assures the code meets expected results.
  • Implementation involves transitioning to the new system. Direct, pilot, and phased strategies exist.
  • Operation and maintenance involve ongoing support and updates.

Alternative Methods and Tools for Systems Development

  • Joint Application Design (JAD) is a group-based method to gather requirements.
  • Rapid Application Development (RAD) combines JAD, prototyping, and ICASE tools for rapid system development.
  • Agile development delivers functionality in short iterations, emphasizing frequent communication and user involvement using techniques like Scrum and MVP.
  • DevOps integrates development and operations teams to speed up deployments.
  • End-user development—sometimes shadow IT—allows users to develop apps without IT help.
  • Design thinking prioritizes user needs to create successful applications
  • Prototyping uses iterative models to refine the system.
  • Computer-aided software engineering (CASE) tools automate various SDLC tasks. ICASE tools integrate upper and lower CASE.
  • Component-based development uses reusable components.
  • Object-oriented development models real-world entities as objects – properties and behaviors.
  • Containers package applications with their needed environments for consistency.
