System Development Life Cycle (SDLC)

•Download as PPTX, PDF•
•

The document discusses the system development life cycle (SDLC) as a systematic method for organizations to implement change through new technologies. It describes the four phases of SDLC - planning, analysis, design, and implementation. The planning phase involves feasibility studies to understand economic, organizational, and technical factors. The analysis phase breaks down the problem and gathers stakeholder requirements. The design phase decides if the system will be internal or outsourced. The implementation phase builds, tests, trains users on, and evaluates the new system. SDLC provides a systematic strategy for large development projects involving many stakeholders.

Implementing Change As new and emerging technologies become essential for survival in an increasingly global economy, organizational change becomes a necessity. SDLC is a systemic method for organizations to successfully implement change.

3

Implementing Change: Systems Approach • A systems approach includes a series of steps to ensure the problem is understood. • Alternative solutions are considered in a systems approach. • A systems approach includes a step to make sure the solution works. (McLeod & Schell, 2007)

4

System Development Life Cycle What is SDLC? • A systemic strategy for large-scale development projects. • A systemic process in four phases to develop an information system. Planning Analysis Design Implementation

5

The Importance of Systemic Methodology • The pitfalls of piecemeal adoption are avoided, no elements are left out! • All relevant stakeholders and information are included, no one is left out! Planning Analysis Design Implementation

6

System Development Life Cycle According to Dennis, Wixom, and Tegarden (2009) “the systems development life cycle (SDLC) is the process of understanding how an information system (IS) can support business needs by designing a system, building it, and delivering it to users” (p. 2).

7

SDLC Planning Phase 1. Do a feasibility study and look at options. – Economical (Can we afford to do this? Will it benefit our organization?) – Organizational and Operational (Will they use it? Do they need it?) – Technical (Can we build it? Do we have the technology to support it?) 2. Create a project plan. – A plan will keep the project on track – A plan can be used for evaluation .

8

SDLC Analysis Phase 1. Analyze by breaking down into parts (draw a diagram). 2. Gather requirements by talking to all stakeholders and technical providers. 3. Create a proposal to present to stakeholders.

9

SDLC Design Phase 1. Decide if the system will be created in house or out sourced. 1. Identify how it will operate and how it will be used by the end users. 1. Reexamine the feasibility study done in the Analysis Phase.

10

SDLC Implementation Phase 1. The system is built or purchased and tested. 2. Training is implemented for end users. 3. A technical support plan is put into place. 4. Use by end users is evaluated.

11

SDLC and ADDIE SDLC ADDIE • Systemic and user centered • Systemic and user centered • Appropriate for large scale • Appropriate for small-scale projects involving many projects involving a limited stakeholders number of people • Systems design • Linear design • The planning phase provides feasibility analysis • Does not work well when to identify implementing large-scale technical, economic, and projects that need flexibility organizational issues • Used by education • Melds education and business perspectives

12

Implementing Change: Innovation • Management and administrators need to be the early adapters of new technologies (Dennis et al., 2009). • No single person can be responsible for change, it is a collaborative process.

13

Implementing Change: Cause and Effect In order to stay competitive in a global society we need to shift from a linear society, that makes top-down decisions to one that is networked and collaborative (Vaitheeswaren, V. & Carson, I. , 2007; Pink, 2005).
