[EXPERIMENT RESULTS] Hidden Hunger Malawi - Buy/grow comparison: Solution / Utility Testing - January 2019


Lean Phase: Solution / Utility Testing

Assumption: It is cheaper to grow than to buy different foods.


Validated learning:

December ‘18 team surveyed 50 mothers. 36% prefered growing for cost reasons, 16% for convenience, and 12% for both.



To confirm assumption that it is cheaper to grow crops vs buying.


Time Box: January 19 Weeks 1-2


Success Metric:

Percentage of people who confirm that growing crops is a cheaper alternative to buying.


Green Light: Assumption confirmed. Confirm with WSU viability of the original purpose of the Hidden Hunger app. Understand why it is cheaper to grow.

Success point: 70% of sources confirm that growing is cheaper than buying

 Orange Light: 50-70% confirm assumption that growing is cheaper. Understand factors that contribute to mixed results. (price of land rental, investment in Tools/resources, irrigation system acquisition & maintenance.

Red Light: The research contradicts our assumption & suggests that it is not cheaper to grow as opposed to buying.

Failure Point: Below 50% of people say growing is cheaper than buying produce


Experiment build:

  1. Organize meeting mothers of young children.

  2. Ask them whether buying or growing food is cheaper.

  3. Analyse data. Make conclusions.



After conducting a survey on a sample of a further 37 Mothers, it was found that 71% of subjects expressed that growing is cheaper to buying and 16% found buying to be cheaper while 13% were unsure. Since 71% of mothers found that growing was cheaper, the assumption is therefore validated.

Since the ‘unsure’ response was invalid to the question, the assumption can be further validated when this count is removed, showing that 82% of mothers found growing to be a cheaper option to buying food.

We also heard reports that the growing option is less financially taxing as it spreads the cost out over the growing season.



Green light. Even if we assume that all ‘unsure’ responses were in fact finding buying to be cheaper, there is still at least 71% of mothers expressing that growing food is cheaper.

Validated Learning:

  • Growing crops is a cheaper alternative to buying food for rural Malawian mothers with young children.


Next Move:

Currency testing. To determine how much or what early adopters would be willing to invest for a solution to malnutrition.

There are some basic phenomenon that are used in the field to test. However there are many individuals using this link so that they can move to the next level in order to deal with them.
