    Study Notes

    Traditional vs. Web-based Development

    • Traditional development prioritizes compatibility with existing systems and sees web-based features as supplementary enhancements.
    • Traditional development uses three paths: in-house development, purchasing off-the-shelf software with modifications, or engaging external consultants.
    • Web-based systems focus on internet access and utilize web-based development platforms.
    • Web-based development uses cloud-based services like AWS, Azure, and GCP, providing flexible and scalable solutions.

    In-House Development Options

    • Reasons to develop software in-house include satisfying unique business requirements, minimizing changes to business procedures, meeting constraints of existing systems, and developing internal resources and capabilities.

    In-house Development Options

    • Reasons to purchase a software package: lower costs, shorter implementation time, proven reliability, minimal technical staff, and future upgrades provided by the vendor.

    Outsourcing

    • Outsourcing is delegating development, operation, or maintenance to external firms.
    • Software-as-a-Service (SaaS) involves renting software from a service provider.
    • Business Process Outsourcing (BPO) involves handing over entire business processes to an outside firm such as customer service operations.

    Offshoring

    • Offshoring is relocating IT development, support, and operational tasks to countries other than where the business is based.
    • The primary motivation for offshoring is cost-effectiveness.
    • Risks and concerns of offshoring include impact on the economy, project control, security issues, disparate cultures, and communication challenges.

    Software as a Service (SaaS)

    • SaaS aligns with Digital Process Management (DPM), which automates and optimizes business processes through digital technology.
    • Benefits of SaaS include eliminating complex software installations, increased flexibility and accessibility, and cost-effectiveness.
    • Shortcomings of SaaS include less control over security and privacy, dependence on stable internet access, customization and integration challenges.

    Selecting a Development Strategy

    • Choosing the best development strategy is crucial and depends on a company's immediate and future needs.
    • System analysts work on the evaluation and selection team to eliminate unsuitable alternatives, rank suitable ones, and present viable options to management.

    Selecting a Development Strategy

    • Financial analysis tools like Payback Analysis, Return on Investment (ROI), and Net Present Value (NPV) help evaluate a project's value.

    Selecting a Development Strategy

    • To determine a project's feasibility, use a cost-benefit checklist: list development strategies, identify costs and benefits, consider future growth, include hardware and software support costs, analyze licensing options, apply financial tools, and prepare a report for management.
