Publishing practical knowledge that transforms businesses.
We publish books written by practitioners for practitioners — rigorously argued, carefully edited, and built to be used, not shelved.
The Science of Business
A Systems-Based Framework for Modern Leadership. The Ultimate Scientific Guide to Building, Scaling, and Sustaining Extraordinary Businesses.
Written by Yusuf Abedin Challawala, this volume treats business not as an art guided by instinct, but as an interconnected system governed by discoverable, testable principles. Across ten parts and fifty-one chapters, it moves from systems thinking through psychology, innovation, strategy, marketing, finance, and growth.
An imprint built on evidence, not enthusiasm.
Excel Knowledge Press is the publishing imprint of Excel Industries, founded to put the same operating discipline that built a manufacturing enterprise into the service of ideas. We commission and edit books that hold up to scrutiny — sourced, tested against practice, and written in plain, exacting prose.
Read our full editorial philosophy →Evidence over opinion
Every argument is tested against data, case history, or direct operating experience before it reaches the page.
Written by practitioners
Our authors have built, run, or advised the organisations they write about — not observed them from a distance.
Edited for use
Structured for a working reader: clear frameworks, defined terms, and no chapter that exists only to fill pages.
