The Pipeline Maturity Model: a measurement framework for sales development organizations

Maturity models fail when they are badges rather than instruments. This paper specifies the Tenbound Pipeline Maturity Model as a measurement framework: four levels (Manual, Assisted, Orchestrated, Autonomous) scored independently across six pillars (Market, Signal, Message, Motion, Mastery, Measurement), with observable descriptors per cell, a scoring protocol, and known failure modes of self-assessment. The instrument is designed so two trained assessors reach the same placement from the same evidence.

Pipeline arithmetic: a quantitative framework for capacity, conversion, and the rate-versus-volume decision

Pipeline creation is a multiplicative system: a target number of qualified meetings divided through a chain of conversion rates yields the required activity volume. This paper formalizes the arithmetic, derives its central managerial consequence (improving the weakest rate compounds while adding volume is linear and bounded by hours), works the sensitivity analysis, and specifies the measurement conditions under which the math holds, chiefly honest stage definitions.

The division of labor in AI-era sales development: a delegation framework

Field experiments establish that generative AI raises novice performance most and that its capability frontier is jagged: quality rises sharply on tasks inside the frontier and judgment degrades on tasks just outside it. This paper translates those findings into an operating instrument for sales development: the delegation map, which assigns every task in the pipeline motion to one of three lanes (delegate, direct, own), attaches a named review point to the first two, and versions as the frontier moves. We specify the construction protocol, the review-point design rules, and the audit cadence.

A taxonomy of buying signals: families, decay, and the signal-to-play mapping

Signal-led outbound outperforms list-order outbound because signals mark the destabilization of a buyer's status quo, but signal is an umbrella term covering events with very different evidential value and very different half-lives. This paper proposes a six-family taxonomy (hiring, funding, leadership change, launch, technology motion, and behavioral intent), characterizes each family's typical decay profile and failure modes, and specifies the signal-to-play mapping that turns a detected signal into a prioritized, relevant motion.

Questions about the research

How the research is made, and how to use it.

What research does Tenbound publish?

+

Four peer-referenced papers with figures, methods and full reference lists, the annual sales tech market map, and the State of Sales Development. The papers cover the division of labour between humans and AI in pipeline work, pipeline arithmetic, pipeline maturity measurement, and a taxonomy of buying signals.

Is Tenbound research free?

+

Yes, and ungated. There is no form. The research is free to read, share and build on, and the one ask is attribution: cite Tenbound and link the issue. Publishing openly is the point, because research nobody can reach does not set a standard.

How is the research conducted?

+

Each paper states its method and its references in full, so a reader can check the reasoning rather than take the conclusion. Where a figure is illustrative rather than measured, the caption says so. Numbers carry the date and the source they came from.

Can I cite Tenbound research in my own work?

+

Yes, that is what it is for. Cite Tenbound and link the source page. No permission request is needed.

Benchmarks are most useful next to your own numbers. Thirty minutes with an account executive, and you get our first read on where yours probably sit against the practice.
