[Stoves] SNV results in Camaroon including TLUD issues

[Crispin Pembert-Pigott]

Dear Ron

 

I have spoken to Cecil and he will provide us a synopsis.

 

A spider diagramme is a common way to show how products compare when
measured using numerous dimensions.  Here is one displaying graphically the
properties chewing gum:

 



 

By using a 'high' rating for the centre and a 'low' rating at the outside
edge, one can create informative charts for as many properties as you want.

 

Social science metrics include preferences, fuels, controllability, lighting
time, ease of learning to use it, appearance, comparison with other products
such as traditional stoves or competing improved stoves, working life, ease
of maintenance, ability to accommodate a range of pots or multiple pots,
price, installation cost, transport to the home issues, attention demand,
fuel preparation requirement, safety concerns, space heating, light casting,
clothes drying ability, fuel drying ability, thermal mass heat storage, fuel
flexibility and many others relating to opinions of users or observers.
Perception of modernity is another.

 

As Verena Brinkmann said at the ISO meeting in Kenya, it is difficult to
measure everything so what is needed is a list of things one might report,
and a toolbox of methods that are used for each item. I was surprised at the
use of the term 'toolbox' because that is exactly what I propose as a
suitable method of determining stove performance across a wide range of
devices, pots, foods, fuels and user habits. If the measurement you want is
relative performance in the place where you plan to sell stoves, then the
test of performance has to be relevant to those circumstances and 'relevant'
includes many social dimensions. 

 

If you want to measure the things that are important to the stove users, you
first have to know what they think is important and then see if the product
addresses those needs or shortcomings well. In the case of funded projects,
the 'customer' is both the funder and the end user so there are additional
measurements required. 

 

By making a spider diagramme or spider chart on can put on the table those
things which the project and users feel are important and rate products more
easily and present comparisons in a pretty small space. In the chart above
you can see that the green product line is inside all the others on every
count. That might be a stove scoring better than other stoves on every score
no matter how many scores one is tracking.

 

Regards

Crispin

 

 

Crispin:

 

                If it is difficult to send a chart or two, could you
identify the Cecil Cook nine variables?
