“What is the right sample size?”, this is a question I get asked quite often. In this article, I will address the question in the context of quantitative surveys. In a separate post, I will review the same question in the context of qualitative research.
The assumptions underpinning the question
This question, “What is the right sample size for a survey?” is based on two assumptions.

If enough people are sampled, the right answer will be reliably found.

Most of the people running companies, projects, and investments in the developed economies around the world have no practical experience of dealing with inflation. The last widespread outbreak was forty years ago. However, inflation is the key shadow facing global economies. (Yes, there are other shadows facing the world, like the terrible situation with Russia and Ukraine, but the key, global economic threat is inflation.)
How bad is it?
Very bad! The USA and UK have inflation rates of 9% and the Eurozone has inflation at about 8%. The trend in most regions of the world is upwards. Governments are starting to try to slow down the rate of increase in inflation (for example, by increasing interest rates), but I think they are doing too little, too slowly.
In many organizations, there is tension between the DIY/SaaS provision of software and the provision of services.
