Critical changes insights provides critical changes risk for the account within 72 Hours. This insight highlights changes which require additional due diligence to avoid business critical outage. It uses AI/ML to look at the risk which the support teams raised the change on and performs a risk assessment against failure of the change or change causing incidents.

Automatically assesses upcoming changes for which the risk is underestimated and alert account team to take additional due diligence before executing the change to avoid a business critical outage.

Filters: The default filter applied when navigating from Landing page is a time period of 72 hours. This can be modified using the filters available.

When a change is created into the ITSM tool it is assigned manually a risk rating. This is normally done only based on the information and properties available at change creation time. It is an indication but could be proven inaccurate due to changes in properties that change over time.

Integrated AIOps Critical Changes insight uses a method that identifies and analyzes the relationship between incident and changes that caused them. The method used looks at four predictors across the following two dimensions:

Change Failure Risk - what is the risk that change executions is going to fail?
Major Incident/Outage Risk - what is the risk that by executing this change an incident/outage is caused?

The linkage between a change request and an incident ticket is identified by two mechanisms. The first one is by explicit mentioning of an incident ticket within a historical change. This is defined as explicit linkage. The other one uses term frequency–inverse document frequency (TFIDF), a numerical statistic that is intended to reflect how important a word is to a document in a collection or corpus.

If a change request and an incident ticket has many common tokens that are otherwise infrequently present, this pair is identified as a text-based linkage.  In the example below, for incident 6, the candidate changes that are related are change 2, change 3, change 4 and change 5.

Integrated AIOps Critical Changes insight uses a method that identifies and analyzes the relationship between incident and changes that caused them. The method used looks at four predictors across the following two dimensions and uses a ‘simple' formula to calculate the AI/ML predicted risk.

Based on the different pieces of information available at change creation time, and experiments to determine the predictors for change risk, the following set of predictors was identified:

Failure Rate by Category: Historic failure rates for changes belonging to a given category
Failure Rate by Owner: Historic failure rates for changes belonging to a given owner group
Failure Rate for similar changes: Historic failure rates for similar changes (based on change description)
Failure rate by configuration item(s): Historic failure rates for involved CI (e.g., hostname, mainframe cluster, etc.)

Failure Rate by Category and Failure Rate by similar changes are evaluated cross account change information. Failure Rate by Owner and Failure Rate for similar configuration item(s) is only evaluated for the data of one account.

When opening the Critical Changes insight, it shows the number of changes within the selected period which have a higher predicated risk rating determined by the Integrated AIOps AI/ML versus the human assigned risk. Also, the details of each change are shown in the table, including a highl level explanation of risk predictors for each of the two applicable dimensions.

When drilling down into one particular change, more details for each of the risk predictors for each of the two applicable dimension and related changes/tickets are made available.

The following image shows how to use the Integrated AIOps Critical Changes insight within the account management system. It supports identifying those changes in the upcoming days for which the AL/ML identified a higher risk profile than is currently set on the change by the change management process.

This use case provides the possibility for the account team to review changes during the daily standup. This to identify changes with higher predicted risk in the next 3 days to do extra due diligence on the change to avoid a business-critical outage.

This use case provides the possibility for the account team to review changes during the weekly CAP meeting. This to identify changes with higher predicted risk in the CAB cycle to do extra due diligence on the change to avoid a business-critical outage.

This use case provides the possibility for the account team to quarterly review changes during continuous improvement process. This to identify changes where the predicted risk is not higher than the human assigned risk. This allows for relaxing the rigor or specific types of changes and time spend on them during the review process.
