Four Steps to a Successful ServiceNow CMDB Deployment

A healthy configuration management database (CMDB) is vital to the success of any organization’s digital transformation. Successfully deploying your CMDB is critical for providing the foundation your organization needs to thrive in a digitally competitive market.

Effective CMDB deployment requires a detailed configuration management plan to implement, design, and sustain a configuration management capability. And while CMDBs do require a lot of upfront planning, it’s an investment well worth making: an effective CMDB plan results in less downtime, reduced costs, and greater service performance.

According to ServiceNow, a well-configured CMDB can save businesses as much as 40 percent in IT costs— exclusive of the costs associated with unplanned outages. A CMDB is an essential IT tool for maintaining high service availability, and when you consider that unplanned downtime on average costs companies $5,600 USD per minute, it is easy to see why building a comprehensive CMDB is critical for an organization.

With the above statement in mind, what is the process needed to implement a panoptical view of the CIs in your organization?

In this blog post, we’ll walk you through creating your own ServiceNow CMDB deployment plan so that you can get the most out of the solution—without any headaches or hiccups.

What Is ServiceNow CMDB?

A configuration management database—an ITIL term for a database where an organization stores information about its hardware and software—provides a big-picture view of all an organization’s IT assets. The CMDB acts as a data warehouse where a company can store critical data about its configuration items (CIs)—components that need to be managed to deliver an IT service. ServiceNow’s CMDB provides information on an organization’s CIs—items like servers, applications, routers, or even portfolios—compiling it with their associated relationships into one accessible solution.

Reaping the Benefits of a CMDB

The most significant benefit that a CMDB offers is that it takes siloed data from across the entire organization that your IT team needs and puts it all in one central location. A CMDB gives IT teams access to all the information they need to maintain service uptime and make IT decisions with confidence.

Successful CMDB deployment offers IT teams and enterprises a number of benefits:

• Helps significantly reduce (and sometimes eliminate) the number of outages
• Enables companies to achieve compliance to avoid potential audit and security fines
• Provides important service context that aids decision-making
• Tracks all virtual assets with their licensing costs and software license costs

CMDB is sometimes referred to as “IT for your IT” because it provides teams with critical information right at their fingertips. When deployed correctly, it ensures that they have the right data to improve business outcomes. The CMDB with its relationships is the foundation for an organization's Decision Engine. Having a complete CMDB allows an organization to operationalize and automate decisions. This allows IT infrastructure to have a faster resolution of incidents, improved efficiency and accuracy in change management, and the ability to design and implement a continuous improvement process.

Define Your Vision and Outcomes First

A preliminary, yet critical task before implementing ServiceNow CMDB in your organization is to identify the purpose of the CMDB: what are the goals, objectives, and outcomes you’re hoping to achieve?

Your configuration management goals should align with your company’s overarching business objectives to ensure you’re taking action on what will have the largest impact on your business. Almost every successful deployment has established goals so take the time now to articulate what you want to accomplish, your projected business outcomes, and how you will measure these outcomes.

It’s also helpful to connect the use cases for your CMDB back to your organization’s specific strategic initiatives. Some examples may include:

• Cloud-first strategy
• Asset management
• Change management
• Data center migration

4 Steps to a Successful CMDB Deployment

To successfully implement ServiceNow CMDB in your organization, you need to have a plan:

• How to get your data into the CMDB
• How to manage the data once it is in the CMDB

Here are four steps to help execute that plan and support a seamless ServiceNow CMDB deployment.

Step 1: Planning

Create a team and governance model

Early leadership buy-in combined with a well-built configuration team and governance structure will create long-term credibility and trust in the configuration management process.

Each deployment team member should have plainly defined roles, authority, and responsibilities. Document each RACI chart (Responsible, Accountable, Consulted, Informed) to ensure every member has the ownership and support they need to make required changes.

In addition to a dedicated team, a configuration control board (or CCB) should serve as a steering committee. They will oversee the implementation and ensure every configuration management effort has a solid value proposition for the organization. The CCB is critical to ensure that your configuration management stays on track and ties back to the company's strategic goals.

Develop your configuration plan

When it comes to creating your plan, we have one saying: don’t try to boil the ocean.

It is critical to start small when designing your CMDB deployment plan. It provides quick wins and provides your team the time they need to familiarize themselves with the CMDB, its function, and its features. Once your team gains a better understanding, grow gradually from there.

Now that your CMDB use cases are identified, it’s time to determine the CI classes and attributes that will support those use cases. Identify the types of CI classes that you want to manage—such as database servers, applications, storage devices, firewalls, application servers, and network routers—ensuring these CIs tie back to your use cases. Once you’ve identified the CI classes, you’ll next want to determine the specific attributes you want to track. For each CI, for example, you may want to track attributes like CPU and memory. Remember, CI tables can get very complex, very quickly—so aim to start as simple as possible.

Using the common service data model (CSDM)—a ServiceNow framework for building out your CMDB—is also important to maximize business outcomes, ensure your ServiceNow instance is organized, and expand the platform without technical debt or sprawl.

Define and identify authoritative sources

Identification of authoritative sources is important for every CI class. Enterprises have invested money in third-party tools to manage the environment and infrastructure. These tools contain a wealth of information that can be used to provide a more accurate and complete CMDB. Sources such as, but not limited to, ServiceNow Discovery, Microsoft SCCM®, JAMF®, or HCL Software’s BigFix® solution can be integrated with the ServiceNow CMDB using pre-built integrations or Service Graph connectors to create a true multi-source CMDB.

Step 2: Implement

Organizational Change Management

Just like any large project, organizational change management (“OCM”) is important to facilitate the adoption of the CMDB and the associated processes and policies. OCM ensures that you get the greatest value from the implementation of the CMDB by helping those impacted by the new processes and technology to (1) understand the value the change brings and (2) make the transition and adopt the changes to how they work. Our approach to effective OCM is focused on the ‘CATS’ framework, by creating a plan rooted in Communication, Adoption, Training, and Sustainment activities to drive the adoption of new processes and changes to the organization in alignment with industry standards and best practices.

Populate data from authoritative sources

Each attribute within every CI class should be clearly mapped to an authoritative source of data such as SCCM, ServiceNow Discovery, JAMF, BigFix, etc. Multiple sources can be configured for the initial creation of the CI, then the authoritative source can be set on each attribute to prevent other sources from changing the value of the attribute going forward. This allows for the CMDB to contain the highest quality data from the authoritative source of choice for each CI class while still allowing the first source to create the CI record as soon as possible. One of the best solutions to this is the Service Graph connectors available from the ServiceNow Store and the IntegrationHub ETL plugin. Both solutions follow best practices for integrating third-party data into the CMDB.

Step 3: Managing

Document policies and procedures

It is important to clearly document policies and procedures for updating and maintaining CIs within the CMDB. Updates to CMDB should follow change processes with reviews and approvals by key stakeholders. As the data within the CMDB becomes more important to both IT and business processes and decisions, ensuring the quality and trustworthiness of the data is paramount. Policies and procedures on how data is populated, managed, and maintained will help ensure the reliability of the data in the CMDB.

Define KPIs and CSFs

Defining Key Performance Indicators (KPIs) and Critical Success Factors (CSFs) are important step in building a successful and healthy CMDB. KPIs and CSFs provide a way to measure success in building and the ongoing maintenance of the CMDB. Having measurable metrics related to Completeness, Compliance, and Correctness of the data within the CMDB ensures that the appropriate data attributes are consistently present and available for important IT and business decisions based on CMDB data.

Data reconciliation

Another step to help ensure a healthy and reliable CMDB is to configure data reconciliation. This helps prevent duplicate CIs when populating data from multiple sources. Using the CI Class Manager, reconciliation rules can be configured on a class-by-class basis. Reconciliation rules help the Identification and Reconciliation engine in locating and updating existing records in the CMDB rather than creating new records every time data is loaded from various sources.

Step 4: Reporting and Auditing

Monitor and communicate the value of your CMDB

A CMDB isn't a “set-it-and-forget-it” IT solution—its health and performance need to be continuously monitored and communicated across the organization.

To measure the health of your CMDB, there are three key performance indicators (KPIs) you should be regularly tracking—all of which are easily accessible from the ServiceNow CMDB dashboard. These metrics—also known as the 3 C’s—are as follows:

1. Completeness: Are all CIs entered in the CMDB or are there gaps in your IT data?
2. Compliance: Are your CMDB CIs configured as expected and meet desired state expectations?
3. Correctness: How is your CMDB data integrity? Are the CIs accurate and up to date without any duplicates?

With insights into the performance of the CMDB, it’s time to communicate that to the broader governance team and key stakeholders. When communicating to various functions, be sure to highlight how a healthy CMDB benefits their processes and priorities. Here are a few examples:

• ITSM: A healthy CMDB improves many core IT service management (ITSM) practices, such as incident, change, and problem management.
• SPM: Strategic portfolio management (SPM) enables companies to plan, align, and execute business outcomes on one central platform. A CMDB enables SPM to merge service information, provides the framework to define and review both service-to-CI and service-to-service relationships, and uses Service Owner Workspace to execute activities.
• SIR/VR: Vulnerability response (VR) uses the data from CIs in a CMDB to provide additional business context to potential vulnerabilities.
• HAM/SAM: Hardware asset management (HAM) provides a strong starting point to empower your CMDB. A CMDB also provides discovery data that software asset management (SAM) requires. The three work together to produce an optimal ITAM workflow.

By empowering IT and bringing otherwise siloed data to one central platform, CMDB offers users across the organization access to information to aid their decisions and execution.
