Situation: A company is planning to add a new network application or wants to implement a new network technology and wants to know the impact to the existing network infrastructure. The customer wants service level agreements but doesn’t know if the existing network can support the required application performance. IT Security staff want to know exactly how the new application will "behave" on the Intranet and what security modifications will be required.

Just because the network seems to be operating smoothly does not mean that it is operating efficiently or that it has the capacity to support one more application. The addition of new technology (like a new protocol, voice over technology, and multicast video) can have unpredictable results on even a stable network. In addition to this, security firewalls require specific and detailed connection information. It can take weeks (or months) to validate and implement security changes on a network. It can take two to three months or more to redesign the network, to obtain funding and to implement the changes. Poor application performance can directly affect your organization’s ability to do its work, which can result in lower productivity, higher costs, and customer dissatisfaction.

Blue Group Solution: Document the impact of a new application, technology change or enhancement including application demographics, capacity, performance and security requirements. This information can then be used to implement or maintain security firewalls, Quality of Service policies, and evaluate performance requirements against existing network capacity. The Impact Analysis profile can be used to predict service levels for your customers. When used in conjunction with our Capacity Planning & Modeling services, Network Impact Analysis can be a very powerful tool for intelligent network planning and risk mitigation.
