Efficiency metrics are amongst managers’ strongest instruments: Setting the best objectives and monitoring progress precisely may help you’re taking your small business the place you need it to go. To be efficient, although, objectives and metrics have to be clear and easy, and the less the higher.
In our rising firm, we’ve discovered that simplicity will increase our odds of reaching what we would like. When our objectives had been too quite a few and too advanced, workers’ selections didn’t sync up inside or throughout groups, which meant teams and people had been tugging in numerous instructions and failing to supply desired outcomes at scale. So we got down to determine a single key efficiency indicator that will unify habits inside one main customer-facing group — the unit that designs, creates, and manages our on-line storefront — and will additionally function a shared foreign money throughout groups, enabling us to make smarter investments within the enterprise. However we realized that going all in on a KPI with out placing some type of examine on it might have severe unintended penalties. We knew that any major purpose needed to be bounded by a constraint, as in, “Maximize X with out lowering Y.”
That is the story of how Agoda, the Asia-based subsidiary of the Reserving Holdings on-line journey group, made its option to a single “KPI + constraint” method that helps us run a very good little bit of our enterprise.1 It took some trial and error to get there; the KPIs we developed and examined alongside the way in which promoted each optimistic and counterproductive behaviors and outcomes. Progressively, nevertheless, we discovered our guiding ideas, applied them, improved our enterprise outcomes, and fostered a tradition of studying and cooperation within the course of.
As a result of we imagine that our experiences and insights could also be useful to different corporations, each inside e-commerce and past, we’re sharing them right here.
We Examined Our Approach Towards a Metric
Because the firm’s earliest days, Agoda has targeted on repeatedly bettering its entrance finish, or storefront — the web site and cellular apps by way of which prospects seek for, choose, and buy journey merchandise — to transform web site visits into gross sales. By rising its conversion charge, a digital enterprise can goal its advertising and marketing extra successfully, as a result of present prospects are simpler to interact than new ones. Revenues from the transformed prospects will be deployed to make the advertising and marketing more and more environment friendly, which pays off in additional conversions.
In mild of those advantages, conversion charge could seem to be the proper major KPI for our enterprise, with return on funding as an apparent constraint. (In any case, why chase down conversions which are exceedingly arduous to get and never prone to repay later?) To calculate conversion charge, you usually divide visitors numbers by gross sales. Sadly, measuring visitors isn’t as simple because it sounds; it’s difficult by quite a few elements, together with unwieldy bots, aggressive advertising and marketing, and the various oblique methods prospects can come to the positioning.
Nonetheless, we knew we wished to reap the advantages of elevated conversions — and do it quicker than the competitors. However how would we go about it and monitor our progress precisely, given how imprecise these visitors numbers could possibly be? To type that out, we began conducting small experiments, one after one other, to check platform modifications that we had purpose to imagine would improve conversions. We used A/B testing, which concerned altering a single aspect (reminiscent of a coloration, a button, a picture, or a message — like “Rooms are restricted!” or “Good selection!”) for a subset of our customers and evaluating the outcomes with a management group’s. “Profitable” experiments — people who generated extra bookings than the management — had been included into our coding and rolled out to prospects extra broadly.
Discovering these winners was tough. Typically, our hypotheses about what would enhance gross sales turned out to be flawed. Round 80% to 90% of our experiments had been good concepts by sensible individuals however didn’t enhance our enterprise; many really made the outcomes worse. For instance, if we informed prospects, “Ebook now or this room can be gone!” we’d inspire them to buy the room — or we’d annoy them and trigger them to desert the reserving course of. As well as, making a software program change might introduce a bug we weren’t conscious of. However these kinds of failures had been a part of the method.
Experimentation helped us decide what was going to work and what wasn’t. Initially, we ran experiments as one-offs, however to be taught from them extra successfully, we constructed a centralized system that allowed us to log and analyze take a look at leads to element after which make and measure modifications to the web site. This experiment “engine” gave us a constant, scalable option to make selections and assess their impression on conversion, and it gave us an early major metric to work with: pace of experimentation.
We Found Velocity’s Execs and Cons
Given how essential experiments had been to our front-end selections, we realized fairly early that we would have liked to extend the pace of our experiment engine. So we set velocity as a major KPI to focus our conversion efforts, defining it because the variety of experiments we ran each quarter. We knew there was no approach we might develop at a significant tempo if we ran too few of them, irrespective of how optimistic the outcomes for every one.
By dicing our experiments extra finely, testing one aspect at a time in order that we might isolate and repair issues quicker, and bringing in managers who had been expert in engineering and course of administration to streamline issues, we went from a couple of dozen front-end experiments per quarter to properly over 1,000 only a few quarters later. Whereas this method helped us determine some ways to extend our conversion charge, it additionally precipitated our web site’s programming code to deteriorate due to how steadily modifications had been made. Briefly, the variety of bugs exploded. Because of this, we launched a constraint on the KPI: code high quality, as measured by the quantity and severity of bugs.
The push for velocity, with the standard constraint, modified how we function. It led us to take a recent take a look at our deployment structure to see how we might implement modifications quicker, however not so quick that we precipitated harm. We created software program instruments to unify, automate, and pace up code deployment and monitoring to lots of of hundreds of servers at our knowledge facilities all over the world.
Many corporations deploy new code solely weekly and even much less typically; we do it 4 or 5 occasions per day. To help that tempo, we rethought our techniques, workers, and organizational construction. Because the variety of bugs elevated, we needed to construct higher high quality assurance strategies. We invested closely in our community operations heart, which tracks our platform’s efficiency to alert us when any vital deviations from regular web site habits happen.
There are at all times deviations, which can be attributable to inner modifications or by exterior elements; solely a robust command of statistics may help you establish which deviations are comparatively regular and that are indications of actual issues. So we developed techniques to seek out statistically vital modifications, even in minor patterns. We additionally constructed monitoring instruments to map code modifications to efficiency patterns in order that we might analyze root causes and resolve issues quicker. And we invested in knowledge techniques to trace visitors in each market, determine vital anomalies, and alert the community operations heart, serving to us see issues we might in any other case have missed and reply to them shortly.
We Revised Our Major KPI
Specializing in rising velocity served a important goal: It helped us run many extra experiments that boosted bookings to some extent. Nevertheless it typically created the flawed incentives. Groups might rating excessive on velocity (and be rewarded for it) by operating many small experiments, no matter whether or not these experiments correlated with significant will increase to the platform’s conversion charge.
To find out which modifications supplied the largest alternatives for conversion, we constructed stronger knowledge evaluation instruments.2 Progressively, it grew to become clear that to foster these bigger alternatives, we would have liked to vary our major KPI.
So we moved to a metric we name incremental bookings per day, or IBPDs. We saved the identical constraint: minimizing the amount and severity of bugs. Our new KPI was reasonably easy: If an A/B take a look at had n1 bookings in variant A (the management group, with no change from earlier practices) and n2 bookings in variant B (the place the change was made), the IBPD impression could possibly be calculated as follows:
![](https://sloanreview.mit.edu/wp-content/uploads/2022/03/MAG_Morgenshtern_Figure1.png)
Each A and B variations had been prone to produce bookings; we wished to pick the extra productive variant.
This KPI was designed to reward groups based on the worth their experiments generated. We arrange agile scrum groups and gave them a goal for IBPDs. We anticipated this method would push groups to run greater and extra bold experiments reasonably than merely extra experiments. We had been in search of the experiments that will generate the most important variety of conversions. To counteract concern of failure, which may lead individuals to make secure bets and create much less worth, we actively inspired groups to attempt large issues even when they had been dangerous and adjusted targets for people who did, giving them room to fail with out penalty.
And, certainly, the IBPD method generated advantages. As anticipated, groups shifted their focus from amount to high quality. In addition they began growing and sharing greatest practices. These insights had been simpler to determine as soon as our experiments had been extra exact, and groups had been desirous to swap success tales, since everybody was searching for good concepts to construct on. For instance, they discovered that it was important to supply prospects with the correct amount of alternative: With too few or too many choices, individuals wouldn’t choose a room. After gleaning this precept from our centralized system for logging and analyzing outcomes, groups started to use it to selections about quite a few options of the web site — determining what number of resorts to indicate in response to a search, the best variety of pictures to show within the gallery, and so forth.
The brand new KPI additionally had essential administration implications. For starters, it allowed us to match conversion charges generated by completely different groups in order that we might decide the place to speculate extra and the place to tug again or change ways. Whereas this method made groups extra aggressive, it additionally made them extra cooperative: They found that in the event that they shared what they discovered, different groups would share insights with them, which helped everybody meet their targets.
Transferring to IBPDs for the storefront additionally helped us see how the KPI might help decision-making all through the corporate. Take advertising and marketing, as an example. There, the first metric was initially the variety of web site guests that campaigns introduced in throughout a selected interval, and ROI (our customer yield for our advertising and marketing prices) was the constraint. That approach of measuring success had its limits, as a result of a lift in visitors didn’t essentially improve conversions. Because the advertising and marketing staff started operating experiments in opposition to IBPDs as a substitute, conversion outcomes improved. If a promotional marketing campaign for a selected market at a selected time introduced in guests, A/B testing completely different approaches inside that very same market and time interval confirmed which kinds of campaigns really produced extra bookings. Whereas exterior elements might assist or hinder a selected marketing campaign, total the A/B method helped us decide extra exactly which campaigns labored. We might then take a look at them in different markets as properly.
Throughout teams, the IBPD metric allowed administration to make smarter trade-offs (for instance, engineering head rely versus advertising and marketing spend) and thus optimize firm investments. We might decide not solely how a lot conversion we had added in every quarter and the way that in contrast with the earlier quarter but in addition which elements had contributed to that success.
Sharing a KPI throughout a number of teams allowed us to combination outcomes on our firm dashboard as properly. Having that view additional fueled decision-making about inner investments. Along with utilizing IBPDs to match groups’ contributions and allocate sources, we might assess product managers’ efficiency. After they fell wanting their objectives, our first response was to maneuver them to a extra productive space to see whether or not their efficiency improved. Successfully, we had been A/B testing our product managers.
We Proceed to Combat Bugs and Bias
Whereas transferring to incremental bookings per day as our major KPI was a major step ahead, we always debated whether or not we had been headed in the best path: What if, as with velocity, the brand new metric precipitated some behaviors we didn’t need? Ought to we be measuring one thing else? What had been we lacking?
At any charge, we knew that IBPDs didn’t remedy each drawback as soon as and for all. For instance, the bug difficulty had by no means utterly gone away. We had been good at fixing giant bugs that had been fairly seen. However addressing small bugs wasn’t engaging to groups, as a result of they had been more durable to seek out and fixing them didn’t produce a major improve in bookings. With sufficient small bugs, nevertheless, the positioning would undergo loss of life by a thousand cuts, for the reason that combination impression was vital — nearly each person would encounter a bug. Ultimately we realized that we needed to set up a transparent threshold even for small bugs; we might tolerate solely a sure quantity at anybody time. If the quantity elevated past the restrict, groups must repair the bugs to earn their full KPI bonuses, even when the IBPD impression of particular person bugs was small.
Extra contentious — and tougher — was the talk about the way to use statistics to advertise habits that was actually helpful for our enterprise. In a well-optimized platform, the overwhelming majority of successful experiments produce IBPDs of lower than 1%. (The extra we optimized this system, the more durable it grew to become to determine modifications that will enhance it additional.) And it was arduous to detect whether or not these small results had been in reality actual wins or simply statistical noise. We wanted to handle this difficulty to make sure that product managers had been making the best selections.
As soon as once more, incentives proved problematic: We wished groups to validate that obvious wins had been straight associated to actual enterprise worth, however we discovered that when bonuses had been tied to IBPDs, groups had been biased to deal with any experiment with optimistic outcomes as a win, no matter whether or not the impression was vital or just noise. This was a pure behavioral response — and it didn’t produce outcomes that benefited the corporate as a complete.
So we additional refined our KPI, calling it unbiased IBPDs, or UBIs. That is the way it works: Each time we flag an experiment as a win, earlier than we roll out the change, we run the identical experiment once more for a sure interval (normally every week). The outcomes of that subsequent analysis run are then factored into the staff’s efficiency. If the primary run seems optimistic as the results of statistical noise, the analysis run is equally prone to seem destructive, so with a big sufficient pattern, the variance cancels itself out. When this occurs, UBIs are zero — and the staff makes no progress towards reaching its KPI objectives (or its bonus). Recognizing the chance that their experiments might produce zero and even destructive UBIs, groups now have an incentive to deal with solely these experiments that produce actually optimistic outcomes as wins. Relatively than simply transferring forward with all experiments that seem optimistic, groups now look rather more carefully at their experiments to find out whether or not the modifications they’re making to the positioning really alter buyer habits.
Even this method shouldn’t be an ideal answer. At scale, throughout a number of groups, UBIs work properly. But when a person staff runs solely 10 or 20 experiments per quarter, it could encounter numerous noise, since this one staff doesn’t have sufficient exams to cancel the variance successfully. (Our rule of thumb: It takes a minimum of 50 experiments to eradicate variance.) As well as, groups could also be reluctant to simply accept outcomes which are unclear, operating experiments many times to get higher statistics. This reduces velocity — bringing us again to the place we began. As with alternative for our prospects, there’s a correct amount of testing: Too little yields inaccurate outcomes, whereas an excessive amount of slows us down and impedes progress.
All that is to say, our major KPI stays a piece in progress. Regardless of its limitations, although, we have now discovered the UBI system to be fairly helpful total. Groups’ behaviors are actually extra aligned with creating enterprise worth by way of conversions, with out considerably hurting velocity. UBIs permit us to measure how a lot groups and people contribute to the corporate’s revenues quarter by quarter, since each incremental reserving will be given a greenback worth. Managers can now make data-based selections about whose efficiency to reward and the place to speculate extra sources within the enterprise.
Altering the Tradition
Our work to outline a major KPI + constraint on the entrance finish and in advertising and marketing has permeated the corporate. Right now, this method to decision-making will be present in each a part of Agoda, even in areas that historically aren’t experiment targeted. In our inventory-purchasing group, for instance, we allocate duties to workers members in 35 nations, and the impression of every activity on enterprise outcomes is estimated in margin factors (a proxy for UBIs in part of the enterprise that doesn’t transfer the needle on bookings). The constraint we’ve imposed is to cut back hostile accomplice habits. (We wish our inventory-purchasing staff to be aggressive in order that we are able to lower prices and improve revenue margins, but when we push too arduous, resort companions would possibly cease working with us altogether.) We run experiments to evaluate which methods correlate with the best margin will increase whereas sustaining fruitful accomplice relationships.
One predictable cultural final result of our give attention to KPIs is that we spend numerous time speaking about measurement originally of each mission — after which we by no means cease speaking about it, to carry groups accountable. One other final result is a little more shocking: Hierarchy now issues much less in our decision-making. Arguing about the way to measure success is far much less ego-based than arguing concerning the selections themselves, and continuous testing proves that even probably the most senior, skilled individuals are flawed more often than not. It’s arduous for leaders to be conceited and pull rank once we typically discover that different individuals’s concepts work higher than our personal. The ability of persuasion doesn’t matter as a lot because it used to both, since we defer to experiment outcomes.
Maybe one of many biggest cultural advantages of unifying and frequently refining our KPIs and constraints is a shared sense of goal. Relatively than having lots of of KPIs, and the confusion and silos they generate, striving for streamlined metrics will get individuals transferring in the identical path. As a result of that helps workers perceive how their work contributes to the corporate’s total success, it additionally fosters cooperation, collaboration, and studying. Staff acknowledge that they profit from what others do and the information they produce and share.
For these causes, we imagine our obsession with setting and monitoring the best KPIs and constraints has been our best weapon in a tricky market. This method defines us and can outline our future, and we predict it may well work for others as properly.
