Thoroughly Explaining the Concrete Process for Building an Ecosystem with Partners and Agencies to Accelerate Business Growth
■ "ELG" will be the "Main Agenda" for Business Growth in the Next 10 Years
Japan is currently facing structural challenges such as labor shortages and recruitment difficulties. In this macro environment, not only the direct sales model that grows by increasing in-house sales, but also the traditional agency channel, where agency sales representatives frequently visit to build relationships with partners, are beginning to reach their limits.
The way to break through these growth constraints and achieve highly efficient expansion with a small number of people is the management philosophy of involving external ecosystems = partners, known as "ELG (Ecosystem-Led Growth)."
■ "ELG MODEL" that Translates Ecosystem Design into an Actionable Form
When executing partner business and ELG strategies, there was no best practice yet available in the world for its implementation.
This book thoroughly explains the "ELG MODEL," which systematically applies a process model with KPIs and measures to the partner domain for the first time, tailored for Japanese companies.
The steps to achieve ELG are broken down into five: "Planning," "Recruiting," "Onboarding," "Activation," and "Retention," with specific methods introduced for each.
■ Co-authored by Two Practitioners Based on Their Real-World Experience
Toshinari Umeki, Marketing Consultant at Dentsu and Co-representative of Dentsu B2B Initiative, and Takumi Inoue, Representative Director and President leading Partner Prop, a startup supporting partner businesses, have systematized "ELG (Ecosystem-Led Growth)," a global trend, into the "ELG MODEL" optimized for Japanese corporate culture.
It is packed with not only the overall strategy and planning but also a wealth of measures that can be implemented starting tomorrow.
