Ask a your colleagues what a value proposition is and you'll get as many answers as the people you ask - maybe more. Helping our clients get clear on what they are trying to achieve with a proposition is often all that's required to focus attention on the right thing and swiftly get results. After all if a group is talking at cross purposes it's frustrating at best and rarely gets much done. We use several labels for different types of proposition and certainly make no claim to define what a value proposition really is - all we want from the labels is to ensure we are all working to achieve the same thing.
The first type of proposition we use is the credibility proposition.
