[EXPERIMENT RESULTS]: Hidden Hunger Malawi - Analysing Accessibility to Food: Utility Testing - July 2019

Experiment Post Reference:


Lean Phase: Utility Test


Purpose: To obtain information about food accessibility for the foods listed in the USTAWI app that is Malawi specific. 


Assumption: Market vendors in Blantyre, Limbe, Nancholi and People’s Markets will provide information about food accessibility for all foods listed in the USTAWI app that is Malawi specific. Food information will also be acquired in a supermarket. 


Time Box: July 2019 Weeks 1-4


Success Metric: Information will be obtained about the accessibility of foods listed under the six food groups in order to ensure that the USTAWI application is Malawian specific



Green Light: Proceed to the next phase of utility testing. 

Success Point: Data is collected from 70% of foods in the revised list of Malawi Foods. 

Orange Light: Repeat experiment in new locations or different seasons until all foods are accounted for. 

Failure Point: 30% or less data was collected from market vendors

Red Light: Data was not able to be collected from market vendors regarding their produce. Revise experiment.



Orange light has been achieved.


Data Collection and Representation:

Old food list and revised food list:

Food Accessibility Survey:

Spreadsheet of results from vendors:

This experiment was performed on a total of 70 market owners across Blantyre, Limbe, Nancholi and People’s markets. Out of 130 foods on the revised list, data was successfully collected for 97 different foods, meaning 74% of foods listed were provided with information about accessibility. Similar information was collected after conducting a survey in the supermarket Shoprite. 


Price and Seasonality:

Price of items varied based on the size of the item, the weight of the item, and the ease at which vendors were able to acquire said food item. Price was also determined by whether the food in question was in season. For example, one data point asserted that tomatoes double in price in the rainy season due to low availability. The seasonality of foods often meant they were not sold during particular months of the year when the food was not in season. Price of foods in Shoprite are more expensive compared to the markets as most of their food is imported.


Data was successfully collected from vendors regarding the acquisition of their food, with 100% of vendors providing this information for their produce. The most commonly reported location vendors sourced their food from was Bvumbwe Market, as seen in Figure 1. Shoprite is a South African owned supermarket. Therefore, their food is acquired and imported from South Africa.

74% of the foods listed under the six food groups have been surveyed and collected the relevant information regarding accessibility. 


Moving Forward:

The survey will need to be revisited and conducted again to ensure that all foods from the newly revised list are covered. The same locations may be used again, although the use of new locations would allow for a wider scope of data, preferably in rural areas as they may grow their own food. Foods that still require data collection are as follows;
