To obtain customer requirements, you need to not only talk to network engineers, but also talk to business unit personnel and company managers. Networks are designed to support applications; you want to determine the network services that you need to support. The steps to identify customer requirements are as follows:

Step 1.	Identify network applications and services.
Step 2.	Define the organizational goals.
Step 3.	Define the possible organizational constraints.
Step 4.	Define the technical goals.
Step 5.	Define the possible technical constraints.

You need to identify current and planned applications and determine the importance of each application. Is e-mail as important as customer support? Is IP telephony being deployed? High-availability and high-bandwidth applications need to be identified for the design to accommodate their network requirements.

For organizational goals, you should identify if the company's goal is to improve customer support, add new customer services, increase competitiveness, or reduce costs. It may be a combination of these goals, with some of them being more important than others.

Organizational constraints include budget, personnel, policy, and schedule. The company might limit you to a certain budget or timeframe. The organization may require the project to be completed in an unreasonable timeframe. It may have limited personnel to support the assessment and design efforts, or it might have policy limitations to use certain protocols.

Technical goals support the organization's objectives and the supported applications. Technical goals include the following:

• Improve the network's response time throughput
• Decrease network failures and downtime
• Simplify network management
• Improve network security
• Improve reliability of mission-critical applications
• Modernize outdated technologies (technology refresh)
• Improve the network's scalability

Network design may be constrained by parameters that limit the solution. Legacy applications may still exist that must be supported going forward, and these applications may require a legacy protocol that may limit a design. Technical constraints include

• Existing wiring does not support new technology
• Bandwidth may not support new applications
• Network must support exiting legacy equipment
• Legacy applications must be supported
