Sources of Knowledge
nowledge management in ITSM isn’t only knowledge articles, captured and maintained in the knowledge management database (KMDB). The knowledge resources available to your organization are much broader than published articles. Your knowledge-management processes should seek to integrate as many sources of knowledge as possible. Some of the most common sources of knowledge available to your ITSM functions (in addition to published articles) are:
Support Tickets
Your support ticket records, including descriptions, notes, and user interaction records, contain a wealth of information about not only the issues users face but also technical details about how your IT environment is constructed. Ticket data is likely your greatest source of knowledge about your IT environment. Most ITSM and helpdesk systems offer capabilities for performing keyword searches against ticket data (not just knowledge articles) to help your agents identify similar issues their peers have seen previously. Key pieces of ticket data you should be leveraging include both text notes and any references to users, configuration items (in your CMDB), linked knowledge articles and monitoring/diagnostic data.
Search History
Most companies have enabled search capabilities for both end users and support agents to help them find various knowledge resources. The records of these searches are a resource themselves. Search history provides insights into what type of issues people are experiencing, the information they are seeking and, most importantly, how they are describing their problems. If a search results in the user finding the resource he or she wants, then that is an excellent outcome. This indicates you have a knowledge resource and you know its use. If the user searches again (because he or she didn’t find what he or she was seeking), then you now have insights into the user’s description, which can help you better craft your knowledge articles. Common search terms are also useful information for prioritizing bug fixes and developing FAQ pages.
Training Documents
New-hire documentation and the reference materials provided when your support team took responsibility for a system are excellent sources of information about how systems are intended to operate, the anticipated maintenance tasks and routine administrative activities. Most helpdesk and ITSM functions have a library of these training documents, but often, once someone is trained, the resources are rarely used. Training documents should be included in your entire knowledge repository, managed and maintained as if they were knowledge articles, thus ensuring they can be accessed and utilized at any time.
Release Notes
Most system releases’ patches and installations include a set of release notes, which explain the changes in the recent version. This includes a list of fixed bugs and issues and new features made available to users and capabilities that have been deleted or retired from the software or hardware. Operations teams performing the installation and change reviewers use these resources frequently, but they are often overlooked sources of knowledge available to support resources. Release notes often include valuable information to help determine what changed in an environment – aiding in the diagnosis of incidents and identification of the root cause of problems.
Testing Records
Most implementation teams maintain a library of test cases, automated scripts and, often, diagnostic tools that are used during the software development process. As pre-release testing is performed, these tests are executed, and the results logged. Both the test scripts and testing records are knowledge resources that can aid your support and operations teams in running and maintaining the services. Test cases and automated scripts can be used as diagnostic tools to determine when the production system is not functioning as it was intended. Benchmarking current tests against pre-release test results can also help support teams focus on specific functions that are not working properly.
Known Issue Database
Most hardware and software is released to users with bugs, defects and missing features of which the development teams are aware, but have not yet addressed. This could be because the risk and impact of the defects are deemed acceptable or it could be because there was not enough time and resources to address the item before the component was released. The known-issue database for your systems, which development teams maintain, is a valuable source of information for support teams. If a user submits a ticket for an item already logged as a known issue, then typically a detailed diagnostic must be performed to identify a root cause. A short-term fix or workaround can be suggested instead.
Subject Matter Experts
Not all your knowledge sources are electronic records. It is important to understand which subject-matter experts are available, either within your service management teams or in the broader support ecosystem. Subject-matter experts may have knowledge, skills, access or experience to address issues that are either especially difficult or simply have not been documented sufficiently for frontline agents to resolve themselves. It is a good practice to capture knowledge from your subject matter experts to reduce the organization’s reliance on individuals, but there will always be a human-knowledge component to IT service management.
