Situation
The brief was to expand a fintech's mobile banking into underserved rural markets.
Complication
Most mobile banking strategies quietly assume connectivity, and those markets don't have it.
Question
What does a rural strategy look like if you start from the constraint?
Answer
Build on USSD and call-based access, which works on any handset and any network, and size the rollout to where that access already reaches. It took first place out of 25+ teams.

The approach

Most mobile banking strategies quietly assume connectivity. Ours started from its absence. We built the expansion on USSD and call-based access, which works on any handset on any network, and then sized and sequenced the rollout around where that access already reached.

Exhibit 1 Schematic

Start from the constraint, then choose the channel

  1. 01 Constraint Low or no internet connectivity across the target markets
  2. 02 Channel USSD and call-based access: any handset, any network
  3. 03 Rollout Sized and sequenced to where that access already reaches

The result

First place against more than 25 teams, many of them from MBA programmes. Framing the constraint first is what separated the answer from the others.
