I discover cycle time one of the underrated metrics for product managers to trace. Enhancing cycle time results in smoother supply, higher effectivity, quicker studying, and in the long term, a greater product.
Though some may argue that monitoring clean supply is a workforce’s or undertaking supervisor’s duty, the truth is that in lots of corporations, the product supervisor wears each the product and supply hats.

What’s cycle time?
Cycle time is the period of time that elapses between beginning work on an merchandise and finishing it.
Why is decreasing cycle time necessary?
Cycle time is among the major velocity measures — and velocity is sweet. Lowering cycle time results in:
- Quicker studying — The faster we ship, the quicker we will consider outcomes
- Greater flexibility — Low cycle time permits us to react quicker and alter the course of course extra simply
- Much less waste — Quicker supply results in much less work in progress, which implies much less vitality wasted on multitasking and managing dependencies
Furthermore, I discover cycle time to be probably the most holistic supply metric to trace. Reaching low cycle instances requires us to observe finest practices similar to:
- Limiting work in progress
- Eliminating wait time
- Engaged on small, unbiased PBIs
- Streamlining code evaluate and high quality assurance processes
- Making certain sufficient readability round PBIs
- Retaining workforce composition and tradition environment friendly
In brief, low cycle time is usually the results of a wholesome supply course of.
8 methods to cut back cycle time
Beneath are among the highest-leverage ways to cut back cycle time I’ve found over the previous couple of years working with numerous groups.
1. Automate as a lot as doable
Automation is vital. If a pc can do one thing, people shouldn’t must.
CI/CD pipeline is a cornerstone of decreasing the cycle time. You don’t wish to spend time doing integration work if it may be accomplished for you.
The identical goes for E2E check automation. If you need to wait a couple of days for each launch as a result of QAs are doing the entire regression manually, you might be doing it unsuitable.
As a rule of thumb, the extra automated the supply course of is, the higher.
2. Use parts
In case your product is previous the preliminary MVP part, it’s most likely time to begin constructing a design system and reusable parts.
You don’t need your builders to code the identical button from scratch each time. Constructing new pages from parts is like utilizing Lego blocks. Every thing is already there. All you want is to attach them accurately to construct the specified determine.
Begin small. Give your designers time to arrange well-documented parts for probably the most generally used interface parts. Then, give your builders area to construct up a parts repository.
It can sluggish you down within the brief run however will repay enormously in the long term.
3. Optimize code evaluate processes
Whether or not it’s ready for evaluations, fixing feedback, or getting approvals, code evaluate (CR) is likely to be a big time-waster. Nevertheless, implementing minor enhancements right here may yield nice outcomes.
To raised perceive how one can enhance the CR course of, let’s break it down into its parts:
Code evaluate time = Time to first evaluate + Time to approval + Time to merge
Time to first evaluate
Time to first evaluate signifies how lengthy it takes from an individual opening a pull request (PR) to the primary individual reviewing it.
Whilst you don’t need folks to drop every little thing and soar into evaluate mode each time there’s a brand new PR, a very long time to first evaluate means extra multitasking on the creator’s aspect.
The wholesome time to first evaluate needs to be in hours, not days.
One tactic that labored properly in my groups was creating two to 3 code evaluate slots in the course of the day. I requested the groups to test the repository and sort out any code evaluate processes a minimum of at the beginning of the day and after the lunch break.
It caps the time to first evaluate time to about 4 working hours.
Time to approval
Time to approval measures the time from the primary evaluate to getting all required approvals. Issues that affect this metric embody:
- Variety of feedback within the PR
- Time to resolve the feedback
- Variety of approvals wanted
The variety of feedback is normally excessive when the workforce is getting on top of things and studying tips on how to code collectively, but it surely needs to be minimized over time. The request dimension is probably the most vital issue right here. If there are 50 feedback in a PR, it’s most likely an unhealthy large PR.
The time to resolve the feedback reveals the depth of the workforce’s work on a given PR. As soon as once more, you don’t need folks to drop every little thing simply because there’s an open PR, however closing PRs in progress needs to be a precedence over creating new pull requests.
The variety of approvals wanted impacts each the code evaluate time in addition to its time consumption. Whereas there’s no silver bullet, you need to guarantee this quantity is related to your objectives.
If you’re launching an MVP, 4 approvals is likely to be an overkill. If you’re a mature workforce with loads of juniors becoming a member of not too long ago, one approval won’t be sufficient to take care of code high quality.
Time to merge
Time to merge tells us how a lot time elapses from the final approval to merging the code and shutting the pull request. Ideally, it needs to be near zero.
A wholesome CI/CD pipeline ought to deal with it for the workforce.
4. Optimize high quality assurance processes
Give attention to making your testing course of as fast as doable whereas sustaining high quality requirements. A number of the ways embody:
Shift testing left
Testing shouldn’t be the final step within the course of. The later you discover a difficulty, the extra time-consuming it’s to be solved. The earlier you have interaction a QA specialist, the higher.
Having a QA specialist evaluate specs and design earlier than beginning improvement may prevent a variety of complications.
Construct high quality tradition
Though a QA engineer is the standard skilled within the workforce, it doesn’t imply that solely they’re accountable for increment high quality. Implement the standard assurance course of for the entire workforce.
Engineers ought to double-check and self-test their work earlier than handing it off to a QA specialist. In any other case, the prospect of discovering late bugs will increase dramatically.
5. Spot and examine outliers
It’s extremely inconceivable that every one work objects could have the identical cycle time. Look out for outliers, particularly those who took considerably longer than the median cycle time:
Examine these outliers and uncover why they took so lengthy. Had been these outliers too large? Did the CR or QA take too lengthy? Is it as a result of technical debt? Then concentrate on addressing these points.
You’ll be able to study rather a lot about your course of effectivity by completely reviewing outliers.
6. Cut back technical debt
I deal with technical debt as a spot between the state of technical excellence and the present state. It could possibly consequence both from oversight or a acutely aware tradeoff. Examples embody:
- Bugs that we determined to not repair proper now
- Lacking documentation
- Inefficient steady supply workflows
- Lack of check automation
- Depreciated libraries and frameworks
- Unused and complicated spaghetti code
- Suboptimal infrastructure
- Cuts in UI and UX implementation
In the long term, the upper the tech debt ranges, the upper the cycle time:
One tactic I like is discussing tech debt on an everyday cadence (e.g., month-to-month threat evaluation conferences).
It’s additionally helpful to have tips for taking and reporting the debt.
For instance, at any time when we take shortcuts or discover gaps, I ask the workforce to report a particular tech debt ticket with a guardrail rule that the overall backlog of tech debt tickets can’t be larger than 200 p.c of the common dash velocity (the quantity varies, relying on circumstances).
Whereas there’s no good reply to how a lot tech debt is suitable, it’s vital to consciously monitor and handle tech debt ranges. Excessive ranges of debt can considerably sluggish you down.
7. Work with smaller items
Ensure that your work objects are as small as they’re possible. The larger the duty, the longer it would take and the extra course of and product threat it would deliver.
Though not each PBI could be cut up into smaller ones, most of them can.
My favourite tactic for decreasing merchandise dimension is slowly capping the utmost variety of story factors per ticket.
Say, if most of my workforce’s tickets are 1, 2, 3, 5, 8, 13, and 21 story factors, step one can be to purpose to get rid of 21 story factors tickets from additional sprints. Then, at any time when now we have 21 story level ticket, we do no matter we will to interrupt it down.
As soon as we grasp it, we change our focus to 13 story factors tickets, and so forth, till we’re glad with the dimensions of our work objects.
Give it a attempt. It’s usually simpler than it sounds.
8. Run experiments
Cycle time is a vital metric that’s price experimenting on in an identical method as you’ll experiment with the product.
Dig round, set hypotheses, plan experiments and see how the metric adjustments. The outcomes may shock you.
For instance, I ran one experiment with the workforce to implement a slack bot reminder to make amends for PRs twice a day.
After working the experiment, the workforce stated they have been irritated by the bot’s fixed reminders and really helpful that we kill it. However they modified their opinions once they noticed that our complete CR time had dropped by roughly 40 p.c since implementing the bot.
Small adjustments can yield shocking outcomes, so maintain experimenting and measuring the outcomes.
