Lab 2.4.1 Establishing Technical Requirements

Step 1: Determine the technical requirements
a. Use word processing software to create a technical requirements document.
b. From the case study document and checklists developed in previous labs, identify and list the technical requirements that will enable the network upgrade to meet the FilmCompany business goals. The technical requirements document provides direction for the network designer in the following decisions:
  • Selecting network equipment
  • Designing the topology
  • Choosing protocols
  • Selecting network services
c. Discuss these technical requirements with another student, or in a group. Consider the range of possible technical solutions to meet the business goals of the FilmCompany.

Step 2: Prioritize the technical requirements
The network designer works with the customer to create a prioritized list of technical requirements. This list will be used to define the project scope.
a. Rank the list of technical requirements in order of priority. Base this ranking on the information in the case study document and discussion with other students.
It is useful to categorize the technical requirements into the following areas:
  • Availability and Performance
  • Security
  • Scalability
  • Manageability
b. List the ranked technical requirements in a table and assign a priority value as a percentage. The total of the percentage values must equal 100.
c. Discuss your priority values with other students. If there are differences in priorities discuss why this has occurred and attempt to resolve them.
d. Save your Project Prioritized Technical Requirements Checklist document and retain it for the next stages of this network design case study.

Step 3: Reflection
When discussing technical requirements with the customer, the network designer must consider the technical level of the audience. Technical terms and jargon may not be clearly understood by the customer. Such terms should either be avoided or tailored to the level of detail and complexity that the customer can understand.
Compile a list of networking technical terms and jargon that may need to be expressed or explained to a nontechnical business customer. Develop an explanation or definition for each term that a non-technical business customer can understand for the purpose of discussing a network upgrade with them.
