Vitala Information Technology & Computer Systems
is the information technology arm of the Vitala Group.
Typically, for new project builds, VITACS’ clients require a cost-effective, reliable, resilient, efficient and secure network system design service.
VITACS uses a systematic top-down network design methodology using a PDIOO (Plan, Design, Implement, Operate, Optimize) structured network design process.
The major components of the methodology include:
Identification of Client Information Technology Needs and Goals
Analysis of Business Goals and Constraints Affecting Network Design
- Analysis of business goals
- Identifying the scope of the network design project
- Identification of client’s network applications
- Analysis of business constraints
