Designing Systems That Function
After Support Ends
Most systems are designed to deliver.
Most fail after handover.
Reported success measures activity, not function.
If it does not function after exit, it does not work.
EDGE5 evaluates success by post-handover function — not project delivery alone.
30 Years Field Experience
Rwanda — ADRA Embrace Program
Approximately 13,000 household gardens established through the 2017 ADRA EMBRACE Rwanda program were later reported by the Country Director as still functioning years after implementation.
Post-Handover Focus
Systems are evaluated against long-term operational function under real-world conditions, including water, labour, governance, and maintenance constraints.
Survival Gate Methodology
EDGE5 applies structured viability assessment through water, labour, soil, authority, and operational capability constraints.
EDGE5 Framework
Design methodology focused on survivability, operational continuity, and function after external withdrawal.
The Standard
Success is not what is delivered. It is what continues to function when no one is there to support it.
The Problem
Most systems do not survive handover.
They function under supervision.
They fail under real conditions.
This failure is not an exception. It is a consistent pattern across development, infrastructure, and community systems.
Why It Happens
Delivery is mistaken for success.
Systems are approved without being tested against real operating conditions.
Authority is not transferred. Dependencies are built into the system. Institutional timelines override reality.
Fragility is not designed out. It is deferred until after exit.
The EDGE5 Position
EDGE5 operates as an independent design authority.
We do not measure delivery. We test survivability.
Every system is assessed against the conditions it must function within — after external support is removed.
EDGE5 is applied where failure after handover is not acceptable.
The EDGE5 Five-Gate Viability System
Five constraints determine whether a system survives after handover. Most systems are not tested against them before exit.
EDGE5 Survival Gate Criteria
Water
Will it function through the worst reliable period — without external supply?
Labour
Can it be maintained within real daily capacity — without fatigue or collapse?
Soil
Will it continue to produce without ongoing external inputs?
Authority
Who makes decisions when external actors leave — and do they have control?
Skills
Can the system adapt when conditions change — without external guidance?
EDGE5 identifies structural failure risk before it becomes operational reality.
EDGE5 identifies structural failure risk before it becomes operational reality.
Most engagements begin before delivery. Some begin when failure is already visible.

David Spicer — Doc Spice Landscape & Water Restoration
EDGE5 works in partnership with David Spicer, a land restoration specialist with deep field experience in water harvesting, earthworks, and landscape rehydration. David trained directly under Bill Mollison, implementing the physical systems that make land restoration work at scale.
Together: EDGE5 designs the system. David builds the earthworks that make it function.
What David Spicer brings to EDGE5 field partnerships
- Dam design, swales, and water harvesting structures
- Land restoration and rehydration earthworks
- Road and access design for working landscapes
- Field experience spanning Australia, Morocco, and New Caledonia
EDGE5 field rules
- Rain is not supply. Storage is.
- Labour is finite. Carrying systems fail.
- Distance defines survival.
- One system that works is worth more than ten that collapse.
If the system cannot function independently, it is not yet designed.
Most systems are not designed to this standard.
Test it before failure becomes unavoidable.
