Introduction to Systems Development
Systems development is the process of transforming business requirements into an operational IT system through a structured sequence of stages. These stages typically include the following:
-
Feasibility studies.
-
Requirements engineering.
-
System design.
-
Software development.
-
Testing.
-
Implementation.
The goal is to create more reliable and manageable systems, reducing reliance on individual developer competence by introducing standardized processes.
The following are the relationships of systems development to other disciplines:
-
Project management plays a crucial role in coordinating resources and ensuring that all stakeholders are aligned with the project goals.
-
Business analysis focuses on identifying business problems and opportunities, often involving IT solutions, and managing system requirements.
-
Systems architecture involves designing a coherent IT infrastructure to support organizational growth.
-
Testing ensures that the developed system functions as expected, even though no system can be guaranteed to be completely error-free.
-
Configuration management tracks system components and changes.
-
Quality control processes and assurance ensures the system meets predefined standards and establishes standards, respectively.
-
Service management involves maintaining IT services and infrastructure, ensuring smooth operations and continuous support after the system is deployed.
On the other hand, offshoring and outsourcing have significantly influenced systems development.
Offshoring involves leveraging lower-cost, high-quality development resources in other countries, like India or Eastern European nations, while outsourcing refers to handing over development work to specialized IT firms.
Both practices offer cost savings but come with potential downsides, such as communication challenges (in offshoring) and a loss of direct control over critical systems (in outsourcing).
