WIQL (Work Item Query Language) is the special query language used in Azure DevOps to find and filter work items, like user stories, bugs, and tasks. To plan a project effectively, teams need to measure their progress using specific data, which requires creating and running good queries.
The first step is to decide what to measure by setting up Key Performance Indicators (KPIs). Common KPIs for project planning include Sprint Velocity, which shows how much work a team finishes in a sprint; Cycle Time, which tracks how long a single work item takes from start to finish; and Backlog Health, which gives a snapshot of how many items are waiting and their priority. These metrics help the team understand their pace, identify delays, and manage future workload.
A process flow showing how KPIs are defined, WIQL queries are authored and optimized, and results are visualized on Azure DevOps dashboards.
To get the data for these KPIs, you write WIQL queries. Authoring a query means using the WIQL syntax to ask for specific work items, such as all tasks completed in the last sprint to calculate velocity. You filter data using fields like Work Item Type, State, and Changed Date. Optimizing a query makes it run faster and use less resources. This is done by simplifying the query logic, filtering on fields that Azure DevOps has indexed for speed, and only requesting the data columns you actually need for your report or dashboard.
The final step is to turn the query results into easy-to-understand visuals. You can implement dashboards within Azure DevOps to display charts and graphs for your KPIs. For example, a velocity chart shows trends over multiple sprints, while a cycle time report can highlight bottlenecks. These dashboards pull data from your optimized WIQL queries. They provide a central place for the whole team to see project health, track progress against goals, and support decisions with real data.

Work Item Query Language (WIQL) is the query language used in Azure DevOps to find and filter work items such as user stories, bugs, and tasks. Teams author WIQL queries to retrieve the specific data required to measure project planning metrics and track progress.
Common project planning Key Performance Indicators (KPIs) include Sprint Velocity, Cycle Time, and Backlog Health. Sprint Velocity shows the amount of work completed in a sprint, Cycle Time tracks the duration an individual work item takes from start to finish, and Backlog Health reflects the count and priority of pending items.
Teams optimize WIQL queries by simplifying query logic, filtering on indexed fields for faster execution, and requesting only the specific data columns needed for reports or dashboards. These techniques ensure queries run faster while using fewer resources.
