Principle
An average sales cycle of ninety days may describe a business where every deal takes ninety days, or a business where half the deals take thirty and half take a hundred and fifty. These are entirely different commercial organisations with entirely different investment characteristics, and the average is identical.
Behaviour
Most commercial organisations of any scale contain at least two distinct motions operating simultaneously under a single reported set of metrics. A transactional motion with short cycles, low ACV, and high volume sits alongside an enterprise motion with long cycles, high ACV, and low volume. The two share a CRM, a forecast, a sales leader, and a headline set of KPIs.
Reported metrics are population averages across both. Average sales cycle, average deal size, average win rate, and average ACV all describe a hypothetical composite deal that does not exist and never has. Forecast models built on those averages assume a single population with a single distribution, and they misprice both motions simultaneously, overstating the predictability of the enterprise business and understating the volatility of the transactional one.
The distortion deepens as the mix shifts. A quarter with an unusually high proportion of transactional deals will show a shortened average cycle and a reduced average deal size, and management will interpret this as an operational change, faster velocity, smaller deals, when nothing has changed except the composition of the denominator.
Two entirely different commercial organisations, with entirely different investment characteristics, and the average is identical.
Evidence
Plot deal size against sales cycle length for every closed deal over three years. A single commercial motion produces a diffuse cloud. Two motions produce two clusters, visibly separated, and the separation is usually stark enough to require no statistical technique to identify.
Once the clusters are identified, recalculate every headline metric separately for each. Win rate, cycle length, discount depth, and forecast accuracy will differ materially, and in most cases one motion is substantially healthier than the other while the blended figure conceals both facts.
Examine whether the organisation's process, comp plan, and management cadence differentiate between the two motions. In most cases they do not, which means the enterprise motion is being managed with a process designed for transactional velocity, or the reverse, and the resulting friction is being attributed to individual rep performance.
Psychology
Organisations resist splitting their metrics because a single set of KPIs is easier to manage, easier to report, and easier to defend. Two sets of numbers invite the question of which one matters, and answering that question requires a strategic commitment about where the business is going that many leadership teams prefer to leave ambiguous.
There is also a comfort in the blend. An underperforming enterprise motion supported by a healthy transactional one produces an acceptable aggregate, and the aggregate is what gets reported. Disaggregating would surface a conversation about whether the enterprise motion is viable, which is a conversation with an owner and a consequence.
Commercial Risk
An investment thesis predicated on scaling an enterprise motion, built on metrics blended with a transactional business, is built on numbers that describe neither. The enterprise win rate is lower than reported, its cycle longer, and its forecast reliability worse, and the transactional motion that was propping up the aggregate does not scale in the way the thesis requires.
The reverse error is equally common and equally expensive. An acquirer who buys a transactional business and finds enterprise deals in the pipeline may model an upmarket expansion that the organisation has never actually executed at scale, because the handful of large deals in the historical data were won by a founder or a single senior rep operating entirely outside the standard motion.
The remedy is not complicated and is rarely applied. Separate the motions in reporting, assign them distinct process and compensation, and require the forecast to be built bottom-up within each rather than blended at the top. The disaggregation is uncomfortable precisely because it forces a decision about which business the organisation intends to be, which is the decision the blend has been allowing everyone to avoid.
