When technology reaches the field, but usability does not

Why access alone is not enough

Many development and impact projects rightly focus on access: access to equipment, access to energy, access to services, access to digital tools.

This is important. But in the field, access is only the beginning.

A product can be delivered, installed and technically functional, while the people expected to use it still struggle with a very practical question:

What do I need to understand right now?

This is especially true in low-literacy and low-connectivity settings, where conventional manuals, PDFs or training materials often do not match the reality of daily use.

A practical example from Senegal

WOM.fm is currently supporting a pilot with WECF International, WECF France and local partner Suxali Jigeen in Senegal.

The goal is to make technical guidance for solar-powered equipment easier to understand for rural women entrepreneurs. The first modules focus on a solar water pump and a solar freezer.

Both are productive technologies. Both can support livelihoods. Both can contribute to women’s economic empowerment.

But both also depend on the user’s ability to understand the system in daily operation.

For example, what does an indicator light mean? Is the system working normally? Is there enough sun? Is the battery charging? Should the user wait, clean the panels, close the freezer, or call for support? What should she definitely not touch?

The technical manuals contain information, but they are largely written for installation and maintenance specialists. For rural women using the equipment, the challenge is different.

They do not need the full technical logic of the system. They need clear, practical guidance that helps them act with confidence.

From manuals to usable guidance

This is where WOM.fm comes in.

We take existing manuals, training documents or technical instructions and turn them into short Visual Audio modules that work better at the moment of use.

The process is not simply translation.

It means identifying the few things the user really needs to know, removing unnecessary complexity, and turning the content into clear, replayable steps.

For the solar water pump, that meant focusing on the most important controller indicators and what they mean in practice.

For the solar freezer, it meant explaining the most relevant charge-controller lights and everyday behaviors, such as not leaving the freezer open too long.

The result is not a replacement for the technical manual. It is a user guidance layer that sits between technical documentation and real-world operation.

Why Visual Audio works in last-mile settings

Visual Audio combines short spoken guidance with simple images.

It is designed for people who may not read fluently, may prefer local-language audio, or may use older smartphones and low-bandwidth connections.

A WOM.fm module can be opened through a short link, QR code or WhatsApp message. It does not require an app install or a login.

This makes the format useful across many last-mile contexts, from solar and PAYGO equipment to agricultural tools, health devices, public service guidance, financial education, and safe-use or maintenance instructions.

In each case, the question is the same: can the user understand what matters, at the moment it matters?

The missing layer in many projects

Across many sectors, technology is reaching communities faster than understandable guidance is.

That creates a gap.

A solar pump is not fully empowering if the user cannot interpret the warning lights. A freezer is not fully useful if the user does not know how to protect the cold chain. A productive asset becomes fragile if every small uncertainty leads to hesitation, misuse or dependency on outside help.

This gap is often treated as a training issue. Sometimes it is.

But it is also a usability issue.

If the product, the interface and the guidance are not understandable in the actual context of use, the impact is limited.

Turning access into confidence

For WOM.fm, this pilot shows a simple but important principle:

Technology becomes more empowering when people can use it with confidence.

That means guidance must be short enough to complete, clear enough to act on, available in the right language, accessible beyond reading, light enough for low-bandwidth environments, and attached to the place or product where it is needed.

This is what WOM.fm is built for.

Not just to publish information, but to make guidance usable at the last mile.

A practical path forward

The Senegal pilot with WECF and Suxali Jigeen is a small example, but it points to a broader opportunity.

Manufacturers, NGOs, energy access programs, public agencies and CSR partners often already have manuals and training content. What is missing is a way to turn that material into practical, accessible, measurable guidance for the people who need it most.

WOM.fm helps create that layer.

Because access is not enough.

For technology to support real empowerment, it has to be understandable in real life.

If your organization works with manuals, product training or last-mile service guidance, we would be happy to explore how WOM.fm can turn existing content into accessible Visual Audio modules.
