The Deconstruction Paradigm

Forget digital and connectivity, invest in your deconstruction mindset!

We believe technology means success. Since the industrial revolution, we had this simple paradigm. Today industries are failing because of this ignorance. Thinking deconstructed and building deconstructed companies solves this.

Synopsis

“We become what we behold. We shape our tools and then our tools shape us.” - Father John Culkin (not Marshal McLuhan)

“We shape our tools the way we see reality. When the tools shape us, they define how we can see the future.”  - That guy who wrote this book

Why are modern companies so much more successful than classic ones? Why is technology not a silver bullet, but people keep investing as if it is?
 
The answer is a mindset that is inherently different and independent from technology. It has impacted both life and business. This book will explain this mindset through real-world examples and through interviews with business leaders who have adopted this way of understanding the world. Deconstructive thinking will enable you to focus on mindset-tool-world feedback loop needed. It will help you avoid using Agile and Design Thinking as mindless tools that won't bring different results. It will help you get over the innovation blocker the industrial revolution has deeply planted in most businesses.

“I have no special talent.
I am only passionately curious.”
- Albert Einstein.

When Marcus was asked why to write this book his answer was simple: "Some ideas are so stubborn, that they keep popping up and eventually get confirmed by reality. Through positive feedback from friends, peers and in projects, I wanted to get the concept of deconstructive thinking out there to make it available to everyone who wants to understand the future."

Marcus looks back at 20 years of working between design and technology. He has seen many ill-conceived projects and bad investments not because the tools or money weren't there, but because the mindset was not right. It might sound theoretical, but a speedboat won't make much of an impact in a pond and a ferrari alone won't make you win a race. This needs to change. If we understand the mindset that drives the change, we can be part of every opportunity change brings to us.

The book should make it easier for you, to:

- understand what Agile or Design Thinking can drive for your business and what the underlying trend is

- know the difference between old and new ways of structuring what a business does and why and see what old aspects are causing innovation not to happen

- have the ability to use deconstructive thinking to get to the real potential a modern company can have

Competition

Everything Bad is Good for You
Author: Steven Johnson
Publisher: Penguin
How referential TV culture is making us smarter.
Comparison:
Also describes a shift in mindset. Similar in tone, similar to defining a phenomenon based on real-world examples.
It is focussed on culture, not business or the way technology structures our lives. More mainstream due to TV theme.

The Inevitable
Author: Kevin Kelly
Publisher: Penguin Books
(A New York Times Bestseller)
Interacting, cognifying, flowing, screening, accessing, sharing, filtering, remixing, tracking, and questioning are Kelly's way to re-label future trends.
Comparison:
Similar audience, style, subject matter regarding technology.
Outdated ideas, just new words to describe the old.
My book is giving actual examples of what to do next, not just new metaphors.

Zero to One
Author: Peter Thiel
Publisher: Virgin Books
Says that companies better have a purpose.
Comparison:
Similar audience but startup focussed. The book does not provide a lot of insight, just opinion or anecdotes that don't offer appropriate steps.
My book shows clear examples what differences in structure and approach a company should take. My book also has a broader audience than just startups.

Outliers
Author: Malcolm Gladwell
Publisher: Penguin
Malcolm Gladwell looks at everyone from rock stars to scientific geniuses to show that the story of success is more based on context than talent alone.
Comparison:
More mainstream but similar in anecdotal and historical evidencing. More academic with data points. Does not offer steps for action.
My book offers a way to reveal an essence of thought that can be applied to everyone.

Future Shock
Author: Alvin Toffler
Publisher: Bantam USA - original ca.1973
Future Shock is about what is happening today to people and groups who are overwhelmed by change.
Comparison:
My most significant reference in ambition and ability to capture the current paradigm. He is essentially the 50 years older version of my book.
His book is more focused on general culture, where my book is slightly more business leaning.

Dear Author,

You worked hard to write your manuscript; finally, it's ready to release. You know that expert assistance is needed, but perhaps you didn’t know that it’s no longer necessary to work with a publisher—especially publishers who charge fees to produce your book upfront and deduct more costs on the back end whenever a book is sold.

1106 Design is an author services company. We provide all the editorial and design services you’d expect from a publisher to turn your manuscript into a market-ready book—editing, cover design, interior layout, proofreading, eBook formatting, and more—at the traditional publisher level. Unlike a publisher, we’ll help you obtain print-on-demand printing and worldwide distribution in your name so that you earn, in most cases, several dollars more for every book sold instead of a measly “royalty.”

We’ll customize a package of services to suit your exact needs at affordable prices ranging from $4,000 to $10,000, depending on your manuscript's word count and complexity. And we’ll manage all the intricacies of book production, so you don’t have to. After this one-time investment, every penny of net revenue from book sales goes directly to you, never to us.

If this sounds like a better way to publish your book, I invite you to browse our services, design samples, no-surprises pricing, outstanding customer reviews, and educational articles at https://1106design.com.

1106 Design has been in business since 2001 and is rated A+ by the Better Business Bureau. We are a “Highly Recommended Expert” at IngramSpark.com and rated "Excellent" at Alli, The Alliance for Independent Authors, at SelfPublishingAdvice.org.

How can we serve you today?
