Every good idea should be supported by extensive research. Businesses can’t afford to go to market with a new product that hasn’t been properly researched. If you’re unconvinced, let us remind you of “new Coke”, which was launched in 1985 after Coca-Cola lost market share to their rival, Pepsi. Coke’s decision to alter their traditional recipe resulted in major outcry from consumers, who inundated the company’s call centers with more than 400,000 complaints.

A year ago, we published a series of best practice for questionnaire development. This year, we would like to highlight some common mistakes that research practitioners should avoid, to ensure their data collection effort is not wasted. We are calling them The Seven Deadly Sins Of Questionnaire Design. The Seven Deadly Sins emerged from an ecclesiastic era, and since then have evolved as broader ethic markers for those who prefer disinfected consciences.
