About the book

Ever Feel Like Your Business is an Adult Daycare-Centre?

Are you constantly repeating yourself, fixing errors, and trying to hold things together? What if it were possible to create a business that runs itself?

You’ve dreamed about it – now it’s time to make this a reality!

If you’re like many seasoned business owners, you’ve tried and failed to systemise your business. The reality is, your shiny business isn’t as functional as it looks from the outside; it’s unorganised, inconsistent, and key-person dependent.

SYSTEMology solves this problem with a proven, step-by-step business systemisation framework – designed so that even the busiest business owner can deploy it. Drawing on 20+ years of business experience and real-life case studies, David Jenyns details the path to complete business reliability.

Tried To Systemise Your Business Before, But Failed?

Well, you’re not alone! Business systems are perhaps the least understood area of business. What’s more, much of the work produced on the topic was not designed for the small business owner. This leaves you confused, overwhelmed and trapped within your business.

That’s where SYSTEMology comes in.

The fact is, successful business owners worldwide are applying SYSTEMology every day to create time, reduce errors, and scale their profits – and now you can too!

About David Jenyns

Meet the Author

David’s entrepreneurial journey began in his early twenties when he sold Australia’s most beloved sporting venue, the Melbourne Cricket Ground.

Since then, his business experience has spanned from franchising retail clothing stores to founding one of Australia’s most trusted digital agencies, Melbourne SEO Services.

In 2016, he successfully systemised himself out of that business, hired a CEO, and stepped back from the daily operations. Through this process, he became a systems devotee, founding SYSTEMology.

Today, his mission is to free all business owners worldwide from the daily operations of running their business. To achieve this, Jenyns spends most of his time supporting the growing community of certified SYSTEMologists as they help business owners implement SYSTEMology. He also delivers workshops, keynote addresses and hosts his own popular podcast – Business Processes Simplified.
