Complex Decisions Deserve Better Diagnosis

Before Halo Strategic, I spent years in travel advertising and ad-tech, working across the full booking chain: airlines including Singapore Airlines, British Airways and Qatar Airways, OTAs, and hotel brands. The lesson that actually stuck wasn't about airlines, or any single part of that chain. It was about how people really make complicated decisions.

Almost nobody booked a flight or a hotel after seeing one advert. They researched. They compared prices across multiple sites. They left without booking. They came back days later. They checked competitors again. They asked someone else's opinion. Then, eventually, they booked, on a date and through a channel that often had nothing to do with whichever ad had first caught their attention.

That's not a guess about behaviour, it's measurable. Sojern, one of the larger players in travel advertising, has tracked individual traveller journeys involving as many as 735 separate touchpoints across 213 days of planning, and a separate journey where 127 of 162 total touchpoints were for the hotel-booking leg alone. Expedia Group's own path-to-purchase research puts the average trip consideration window at 71 days, and finds travellers viewing 141 pages of content in the 45 days before they book.

Sit inside that data for long enough and a specific kind of professional humility sets in. Attribution isn't difficult because the tools are bad. It's difficult because the decision itself is genuinely complex: multiple people, multiple sessions, multiple channels, spread across weeks, all collapsing down into what looks, from the outside, like one simple purchase.

Businesses aren't that different. That's the part that transferred.

A founder looks at one KPI. One campaign's performance. One disappointing quarter. One dashboard. And often, understandably, assumes they've found the answer, because the number in front of them is real and it's telling a clear story. But a real commercial outcome, whether a customer books a trip or a business's growth stalls, is almost never the product of one single, clean cause. It's the accumulated result of dozens of interconnected factors, most of which never show up in whichever single metric someone happened to be looking at.

That's not a reason to give up on measurement. It's a reason to be honest about what one number can and can't tell you on its own. A booking is one event, made of a hundred prior touchpoints, spread across a customer's life. A quarter of underperformance is one event too, and it's just as unlikely to have one clean cause sitting neatly behind it.

The lesson was never really that attribution is hard. The lesson was that complex systems rarely have simple explanations, whether the system is a customer's booking journey or a business's whole commercial engine. That's true in travel. It's true in SaaS. It's true for agencies, for manufacturers, for founder-led companies doing five million a year and companies planning their next stage of growth. Complexity doesn't announce itself. It just quietly sits underneath whatever single number someone's decided to trust.

That's the actual reason Halo starts every engagement with diagnosis, not a recommendation. Not because diagnosis sounds more careful. Because treating a hundred-touchpoint decision like a one-touchpoint decision is exactly how businesses end up fixing the wrong thing, confidently.

A few honest questions worth asking before trusting a single number to explain a commercial outcome:

• If this quarter's number is disappointing, how many separate decisions and handoffs actually fed into it before it became one line on a dashboard?
• Is the metric in front of you the cause of the problem, or just the last visible symptom of something further upstream?
• Would a different person, looking at a different part of the business, tell a different story about what's actually going on?
• Are you diagnosing the constraint, or reacting to whichever number happened to be in front of you this week?

One travel booking can involve over a hundred touchpoints. Most businesses still expect to diagnose their own growth problem from a single dashboard.

This is the same instinct behind Halo's approach to reporting and measurement, explored from a different angle in The Reporting Problem Hiding Behind Good Performance and The Four Things Halo Actually Measures. The underlying misconception it corrects is the same one covered in Why Successful Businesses Don't Think They Need Halo: that a business performing fine on one visible measure has necessarily found the right answer.

What people ask about diagnosing complex decisions.

If a single number, a single campaign, or a single quarter is currently driving a big decision in your business, a Commercial Diagnostic is a 90-minute session built to find out what's actually behind it, before you act on it.
