The Household decision making process for building a latrine - For a poor household, the decision to build a latrine for the first time can be a big one, as such, it can also be a long process. The arguments for and against building a latrine will be carefully considered after seeking advice from friends, relatives and acquaintances. When the householder is satisfied that building a latrine will be beneficial the process will commence. Despite good intentions, the building process may be hindered by any one of many seemingly insurmountable obstacles. Using the model of ‘Adoption Decision Making Stages’ the project designer may gain a better understanding of where their target population is on the ‘Preference, Intention, Choice’ decision making chain, which suggests what constraints the household may be facing.

To encourage and enable a householder to build a latrine, the following conditions need to be in place:

• Reliable Supply Chains
• User Demand
• The Right Policy Environment

Proceeding when only one of these three elements is available increases the chance of project failure. For example, creating demand is futile if the supply chains are incapable of delivering what is demanded of them by customers.
