What is the TAF for?
The Technology Applicability Framework (TAF) is a decision support tool on the applicability, scalability and sustainability of a specific WASH technology to provide lasting services in a specific context and on the readiness for its introduction. The TAF can be used to
start discussion, documentation and sharing experiences about a WASH technology and approaches to scale up this technology
assess the potential of a specific technology with respect to applicability, scalability, sustainability and uptake in a specific context,
assess readiness of a sector to scale up this technology including identification of potential measures for improving uptake,
monitor performance of technology and its introduction process.
When to apply the TAF?
The TAF should be applied when a technology is being piloted. It can also be used to support monitoring and evaluation of progress and performance of technology introduction processes.
How does it work?
The TAF is designed as a participatory tool. It is applied using a stepwise process. It uses specific questionnaires for screening and field questionnaires for the assessment. Information needed are collected through desk studies and field visits. All relevant actors are involved in the collection of data and in the generation and discussion of results. This allows all actors, including representatives from national and local government and users of the technology such as communities, to bring in their perspectives and views and to hear the opinions of other actors.
Where are the limits?
The TAF is designed to assess a single WASH technology (e.g. a pump or a toilet design) which is - or will be - used to provide WASH services in a district or region. The TAF can also be used to assess complex systems such as a piped supply with tanks, pipes and taps. However, prior to the TAF assessment of a system, the boundaries for the assessment have to be defined. Field visits are used to verify the context and boundaries of each TAF application. The TAF is designed as an assessment tool for a single WASH technology in a specific context, not as a selection tool which selects between various technologies.
Four steps in the TAF assessment
The assessment within the TAF follows a procedure with four steps:
The TAF process starts with a screening in step (1). The screening focuses on two key questions:
Is there a need for this technology?
Is the technology at all feasible in this region?
If the screening is positive, the technology will be comprehensively assessed in step (2).
In step (3) the results are collected and presented.
In step (4) all results are comprehensively interpreted.
