The official figure

The Institute of Service Excellence (ISES) at the Singapore Management University (SMU) just released the results of its annual customer satisfaction survey of the transport and logistics sector in Singapore. It was conducted between April and June of this year, and generally found improvements over last year's results. These include improvements in its scores for public bus transportation (up 5.3 points over a 100 point scale) and the MRT (up 3.7 points). 

As expected, nobody I know who take public bus and MRT transport as often as I do (which is 5 days a week commuting to and from work) can reconcile their experience with the results of this survey. In fact, there are probably more who I do not personally know (and thus cannot vouch for) who would express the same opinion. Just read the comments in response to the report in Today Online. None of these comments expressed agreement with the findings. Some questioned its survey methodology. Others didn't bother - it was just plain wrong, they said. Yet others threw scorn on ISES, saying that it has lost credibility. 

Let me say first that ISES, which is under SMU, has done this survey since 2007. It must be credible. Otherwise, it would have closed its doors. There is always the fine print - and point - in interpreting statistical figures. The news media are often at fault in giving the wrong impression. In this case, news headlines suggested that public transport service has improved overall ("Singaporeans are satisfied with public transport system" - Todayonline,  "Satisfaction over public transport has increased..." - CNA). And you know, in the age of the sound bite, that's all that anyone is interested in reading - the long suffering man in the street who will disagree, not knowing what exactly he disagrees with, and the smug corporate transport executives who will agree, again not knowing exactly what they agree with. So we are always back to square one.

Survey results are raw. Only when you begin to look closer at the results in specific contexts can you make any meaningful inferences and arrive at certain conclusions. Truth be told, the same set of survey results can be interpreted in any number of ways, depending on what you want to say, or hear. So the 'saying', or interpretation,  is important. And when you look closely at what the ISES researchers say, they agree that frequency and punctuality needs to improve further, something that everyone has been saying all along. For the man in the street, the improvement needs to be significantly more. For the transport executive, that's distilled to a number, no more nor less. And this is where they don't see eye to eye. As the ISES researchers have rightly pointed out, it is, after all, a matter of perception although this did not stop them from quantifying such an un-quantifiable attribute.
