Agencja K2, na swoim Facebookowym profilu podała oszacowane (zafakturowane? ;) statystyki pracy nad serwisem PKO BP, który właśnie pojawił się w swojej nowej odsłonie. Nawet jeśli podane wartości nie są w 100% pewne, to pokazują przybliżony czas, niezbędny na przebudowywanie dużego serwisu. Dane ciekawe i wartościowe jako punkt odniesienia, przy szacowaniu czasochłonności podobnych projektów. Stworzenie serwisu PKO BP zajęło:

• 1 100 h pracy działów Strategii, Design i UX
• 1 500 h poświęconych na analizę
• 11 000 h pracy działu IT
• 700 h poświęconych testom quality
• 700 h pracy content edytorów
• 2 800 h pracy działu Client Service

Dużo bełkotliwych tekstów, które pojawiają się w moim czytniku RSS, intensywnie wiążą się z tegorocznymi buzzwordami czyli AgileUX i LeanUX. Poniżej wyimki z mądrego tekstu Leisy Reichelt, dowodzącego, dlaczego techniki zwinne niekoniecznie są dobrym rozwiązaniem w modelu agencyjnym.

Firstly, the client effectively outsources the work. They create a separation between themselves and the people who are doing the work.
(…)

The lack of integration between the company who needs the project done and the company who is doing the project creates a very different shape to a typical (effective) Agile or Lean team, and it makes it difficult to work effectively.

It also introduces another ‘customer’ to the mix – one that is not the end user customer, but one who will sign off the project and pay the bills – so,probably, a more important customer to the agency than the *real* customer that the project is being created to serve.
(…)

Secondly, when the client outsources the work, they feel as though they’re outsourcing the risk.
(…)

Thirdly, when you’re paying an agency a lot of money (and you usually do), you want to feel confident about what you’re going to get when then money is spent.

A typical consent dialog was shown in 223 experimental variations to 80,000 users of an online privacy tool. We find that polite requests and button texts pointing to a voluntary decision decrease the probability of consent—in contrast to findings in social psychology. Our data suggests that subtle positive effects of polite requests indeed exist, but stronger negative effects of heuristic processing dominate the aggregated results. Participants seem to be habituated to coercive interception dialogs—presumably due to ubiquitous EULAs—and blindly accept terms the more their presentation resembles a EULA.

For my experience, I noted that customers often make a big deal about having everyone on their team be able to update the content, but then no one makes any updates at all, beyond a few words here and there. Most people want the possibility of control without any of the responsibility to do the work.

All of us agreed, somewhat reluctantly, that none of us has had much success with collaborative authoring.

Measurements of user satisfaction and UX seem to be an artistic rather than a scientific endeavour, with the scope being limited by the imagination and creativity of researchers. Such a diversity of measures not only causes confusion but also fragmentation of the field. Efforts for validating and standardizing these measures are called forth;

ƒTo reduce usability measures into a single measure is bound to lose information, because objective and subjective usability measures may not correlate or even contradict. Similarly, evaluations of UX should not rely on subjective measures – the current predominant type; it is important to develop reliable and valid objective measures (i.e. psycho-physiological and biophysical);
