AUTHOR · LEADERSHIP & INSTRUCTIONAL DESIGN

The science of human performance, applied.

Two books, one discipline. Whether the challenge is leading a multi-generational workforce or designing learning that actually changes behavior, the question is the same: what truly improves human performance — and how do you prove it?

The Books

The Relationship Factor — front cover

The Relationship Factor

A leadership guide that integrates three frameworks — Leader-Member Exchange theory, generational cohort dynamics, and Human Performance Improvement — to help leaders develop and retain employees across Boomer, Gen X, Millennial, and Gen Z cohorts. Practical, research-grounded, and built around the relationships that drive performance.

Three Frameworks, One Model

LMX, Generational Cohort Theory, and HPI woven together into a practical leadership approach

13 Chapters Across Four Parts

Foundational theory through application, with reflection questions at every part divider

HPI Throughout

Human Performance Improvement in every chapter, with an honest look at AI as a performance challenge

A Practitioner’s Guide to Instructional Design

A working designer’s guide that walks the full ADDIE lifecycle — Analyze, Design, Develop, Implement, Evaluate — and at every phase gives you three things: the theory you need (and only that), a worked example from real projects, and a template you can copy onto your desk tomorrow morning. Written for the practitioner with a project starting Monday.

The Full ADDIE Lifecycle

A chapter per phase, each built on the same scaffold — theory, worked example, templates, and pitfalls

Performance First

Gilbert’s Behavior Engineering Model threads through every phase — always asking whether instruction is even the right answer

A Copy-and-Go Toolkit

Every template gathered into the ADDIE Designer’s Toolkit, plus a closing chapter on AI as a tool that raises the bar

The Through-Line

One question behind both books

Before you build a course, a program, or a leadership initiative — does it actually improve performance, and can you prove it?

Start with the real problem

Diagnose before designing. The most valuable practitioner can say when training — or a new program — is not the answer, and prove it.

Theory in service of practice

Only as much theory as the work requires, traced to its originators and paired with worked examples and templates you can use immediately.

Measure what changed

Outcomes over process. Evaluation discipline that connects learning and leadership to behavior, results, and return on investment.

Speaking & Workshops

Talks that change how teams work

Keynotes, workshops, and webinars for leadership teams, L&D departments, and conferences — each built on the books and delivered with the same rule: practical tools your people use the next morning.

“Could they do it if their life depended on it?”

The one-question diagnostic that stops organizations from buying training for problems training can’t fix — and what to do instead. Built on Gilbert’s Behavior Engineering Model.

Keynote · Half-day workshop

The Relationship Factor: Leading Four Generations

How leader-member relationship quality drives performance across Boomer, Gen X, Millennial, and Gen Z employees — and the habits that build it deliberately.

Keynote · Leadership offsite · Webinar

AI Didn’t Replace the Designer — It Raised the Bar

What AI actually changes in L&D production work, which human disciplines become more valuable, and how to keep the design from bending to the tool.

Nathan Chambers
Author & Practitioner

Nathan Chambers, M.S., ABD

Nathan came to this work not from the academy but from the table — sitting across from business owners certain they needed a course, and watching expensive training get built, delivered, and never measured. He writes from practice: a researcher and instructional designer focused on what actually improves human performance.

Master’s Degree

M.S. in Human Performance Technology — Boise State University, Organizational Performance and Workplace Learning (OPWL) program

Doctoral Candidacy (ABD)

Capella University · Training, Learning & Performance Improvement
Full doctoral coursework completed; formally approved dissertation research plan

His writing synthesizes that graduate and doctoral study with current scholarship and real engagements — bringing evaluation discipline to teams that had never evaluated anything, navigating healthcare compliance, and studying why front-line managers so often fail to coach.

Short bio (~60 words)

Nathan Chambers, M.S., ABD, is the author of The Relationship Factor and A Practitioner’s Guide to Instructional Design. He holds an M.S. in Human Performance Technology from Boise State University’s OPWL program and completed full doctoral coursework in Training, Learning, and Performance Improvement at Capella University. He writes from practice about what actually improves human performance.

Long bio (~140 words)

Nathan Chambers, M.S., ABD, writes at the intersection of leadership, learning, and human performance improvement. His books — The Relationship Factor, on leader-member exchange across a four-generation workforce, and A Practitioner’s Guide to Instructional Design, a performance-first walk through the full ADDIE lifecycle — share one discipline: diagnose before designing, and measure what changed. Nathan came to the work from practice, not the academy: years spent across the table from business owners certain they needed a course, watching expensive training go unmeasured. He holds an M.S. in Human Performance Technology from Boise State University’s Organizational Performance and Workplace Learning program and reached all-but-dissertation status in Training, Learning, and Performance Improvement at Capella University before choosing to write from practice instead. He speaks and runs workshops on performance diagnosis, multi-generational leadership, and AI in L&D.
