Introduction

Flow Metrics, as described by the Flow Framework®, provide a clear indication of whether your value streams and your Flow are sufficient to support targeted business outcomes (like improved adoption, revenue and quality, reduced costs, and employee turnover).

The Flow Metrics dashboard features four Flow Metrics and Flow Distribution for each product value stream.

  • Flow Velocity gauges whether value delivery is accelerating. Flow Velocity is the number of Flow Items of each type completed over a particular period of time. This is also referred to as throughput.
  • Flow Time can identify when Time to Value is getting longer. Flow Time measures the time it takes for Flow Items to go from ‘work start’ to ‘work complete,’ including both active and wait times. 
  • Flow Efficiency can identify when waste is increasing or decreasing in your processes. Flow Efficiency is the ratio of active time vs. wait time out of the total Flow Time. 
  • Flow Load monitors over and under-utilization of value streams, which can lead to reduced productivity. Flow Load measures the number of Flow Items currently in progress (active or waiting) within a particular value stream. 

In addition to the four Flow Metrics, Flow Distribution helps prioritize various types of work during specific time frames in order to meet a desired business outcome. Flow Distribution measures the ratio of the four Flow Items completed over a particular window of time.

Getting Started with Flow Metrics

To access your Flow Metrics dashboard, click the Flow Metrics tab.

Tip: You can always click the (question) Help button to find more information about a topic.

Customizing your Dashboard

For a personalized view of your Flow Metrics dashboard, Viz offers customization options such as custom date range, advanced filters, and more. 

You can set the date range for your metrics and the desired grouping by day, week, month, or quarter.

Group by Day, Week, or Month

Or, set a custom date range to view your metrics for a specific time period. 

Set Custom Date Range

You can also filter the artifacts in your dashboard using the advanced filter — which filters your metrics by artifact type.

Click the Artifact Filtering Button

(warning) Note: When setting a filter, be conscious of relationships between different artifact types to prevent double counting — for example, selecting both stories and their parent epics could result in misleading velocity numbers as a result of double counting.

Artifact Filtering Screen

If using smart filters, Flow Distribution will show the Flow Distribution breakdown of the four Flow Items in their totality. If you want to understand distribution at a more granular level, the advanced filter will allow you to compare velocity breakdown of the specific artifact types selected.

Flow Velocity

Flow Velocity measures productivity by showing how many Flow Items of each type were completed over a particular period. 

Track Flow Velocity to improve estimates and forecast how much work your team can deliver.

You can use this metric to:

  • Identify whether value delivery is accelerating, decelerating, or staying constant.
  • Prompt investigation into how to increase Flow Velocity when it’s too low, for example, by investing in talent, architecture, or infrastructure. Since wait time is the largest factor that stalls Flow, efforts to increase Flow Efficiency can also dramatically improve Flow Velocity.
  • Prompt research into the root cause of a noticeable change in velocity, for example, a new process, change in workflow, or staffing change.


Flow Velocity is defined as the number of completed Flow Items minus the number of re-opened Flow Items per time interval. 


Flow Velocity is...This may indicate...
(tick)High

Value delivery is accelerating.

(error)Low and Flow Time is high

Interruptions from context switching are present.



Flow Velocity

Tip: High Flow Velocity translates into more value delivered.



Flow Load

Flow Load measures work in progress (WIP) by showing the number of Flow Items being actively worked on in a value stream. It includes all Flow Items in either an active or waiting state.

Utilize Flow Load to discover the impact too much WIP has on your speed metrics and your team’s happiness.

You can use this metric to:

  • Discover the product value stream’s optimal Flow Load, when Flow Velocity is high and Flow Time is low.
  • Work with business stakeholders to balance demand vs. capacity correctly.
  • Understand how WIP impacts business outcomes, like employee happiness and engagement.


Flow Load is represented as the total number of Flow Items in active or wait states recorded at the end of each day.


Flow Load is...This may indicate...
(warning)Stable

Only a small amount of WIP is being completed.

(error)High and Flow Time is low

A percentage of work is being neglected.

(error)

High

Too much work in progress (WIP). Too much WIP results in delayed delivery of value, increased costs, decreased quality, and unhappy employees. When demand is higher than the team’s ability to consume it, which often leads to burnout.

(error)High and Flow Time is high

Context switching is likely the culprit.

Flow Load

Tip: High Flow Load will negatively impact velocity.

Finding Bottlenecks

The bottleneck finder uses Tasktop’s built-in expertise to analyze your data and pinpoint the bottlenecks in your process — so you can see where your work is slowing down and piling up.

There are several types of bottlenecks:

  • Resource scarcity
  • Lack of automation (e.g., CI/CD pipelines, testing)
  • Process timing (e.g., funding approvals, end-to-end testing, waiting for change approval)
  • Dependencies

Tip: If you'd like to learn more about these bottlenecks, see the coaching videos below.

To access the bottleneck finder, click Find Bottlenecks on the Flow Load card.

Click 'Find Bottlenecks'

You’ll then see the Find Bottlenecks drawer — which includes values for current artifact count, max artifact count, and state duration index.

  • Current Artifact Count represents the current number of artifacts in each state, as of the most recent polling by Viz.
  • Max Artifact Count represents the maximum number of artifacts in each state at any time during a specified date range.
  • State Duration Index allows you to compare the relative amount of time artifacts spend in each state.

These values can be used to compare the number of resources available to perform work in a particular state — determining how active work truly is in that state.

Find Bottlenecks Drawer

You can use filters to sort by Flow State, Artifact State, Flow Item, Artifact Type, Tool, and Project.

Filter by Flow State, Artifact State, etc.

To better understand your Flow Metrics and validate the data pulled into Viz, click a value in the Current Artifact Count column to see the contributing artifacts for each modeled artifact, or simply click the artifact in the chart.

View Contributing Artifacts

On the Contributing Artifacts screen, click the link on an individual artifact to view the artifact within the external tool itself (assuming you have credentials with appropriate permissions).

Flow Time

Flow Time measures time to delivery by tracking the total time from work start to work complete, including both active and wait states. 

Track Flow Time to help your team become more predictable and answer the question, “When will the work be done?”

You can use this metric to:

  • Identify when time to value is increasing or decreasing, so you can investigate the contributing factors.
  • Predict time-to-market based on previous performance.
  • Assign flow time goals for each Flow Item to ensure that all Flow Items are completed within an adequate time frame. This helps to ensure that production incidents (defect Flow Items) are not the only Flow Item handled expeditiously.


Flow Time is calculated by averaging the total days work remains in both active and waiting states from work start to work complete.


Flow Time is...This may indicate...
(error)Too low

Work is not being tracked accurately (e.g., moving directly from 'New' to 'Done').

(error)High and Flow Velocity is low

Too much work in progress (WIP). Too much WIP increases context switching and wait times and drives down efficiency and velocity.

Flow Time

Tip: Shorter Flow Time means faster time to market.



Flow Efficiency

Flow Efficiency is a measure of waste in a value stream, where work is waiting. It tracks the ratio of active time vs. wait time out of the total Flow Time.

Measure Flow Efficiency to help you visualize wait time from bottlenecks so that your team can figure out how to reduce problems from wait time constraints.

You can use this metric to:

  • Measure wasted time and delays. The lower the Flow Efficiency, the longer work is stagnating in a waiting state. This points to the existence of bottlenecks, inefficient processes, dependencies, or lack of resources.
  • Track reduced wait times. This metric can be used in conjunction with the other Flow Metrics to focus on reducing wait times. For example, improving automation can reduce the active time component of Flow Time and decrease Flow Efficiency.


Flow Efficiency is calculated by dividing the number of days a Flow Item stays in an active state by the number of days a Flow Item stays in active and waiting states combined.


Flow Efficiency is...This may indicate...
(error)Very high (e.g., 40%+)

Your state mappings are inaccurate. For example, if your 'New' state identifies work that is past the line of commitment, that state should be re-mapped as either 'Waiting' or 'Active.'

(error)Low

Work spends a lot of time in a waiting state, which points to bottlenecks, inefficient processes, dependencies, and a lack of resources. You can create a business case for investing in the bottleneck based on the expected improvement to Flow Time and Flow Velocity.

(error)LowAn increase in your Flow Load and larger queues in the value stream.

Flow Efficiency

Tip: Ideal Flow Efficiency is around 30-40%.



Flow Distribution

Flow Distribution measures de-facto investment in different value creation by showing the ratio of Flow Items (features, defects, risks, and debt) completed over a particular period. 

Utilize Flow Distribution to bring visibility to different types of work across the value stream so you can see where the emphasis lies from a prioritization perspective.

You can use this metric to:

  • Understand whether resource allocation is in-line with business priorities and if not, make adjustments.
  • Drive prioritization discussions with business stakeholders by making work distribution visible.
  • Assess how the distribution of work on technical debt impacts future Flow Velocity -- does tackling 20% debt each release ensure that feature work does not slow over time?
  • Proactively plan Flow Distribution such that it matches current business priorities. For example, in the Incubation phase, the distribution should have a higher Feature distribution as you're pushing to have a decent MVP for launch. However, once you've launched, you can expect Defect and Debt distribution to increase. Refer to the illustration below to get an idea of what an appropriate distribution is per product lifecycle stage.

Target Distribution per Lifecycle Stage

Flow Distribution is the relative distribution of Flow Velocity across the four Flow Item types (feature, defect, risk, debt).


Flow Distribution is...This may indicate...
(error)High for defects

Feature capacity is diminished by unplanned work or poor testing. Possibly too little work is being invested in debt.

(error)Lacking debt and risk

Work is neglected, hidden or done by a centralized team. In a product-oriented value stream, ideally the product value stream would also be doing its own debt and risk work.

Flow Distribution

Tip: Healthy Flow Distribution includes appropriate levels of risk and debt.
