’Play’ model of information system design makes teammates of users and designers

12.01.2006


"Play" or back-and-forth dialogue between users and designers can lead to IT systems that are more responsive to the subtleties and ambiguities of users’ different perspectives, say Penn State researchers.



And because it makes users and designers teammates during the development process, the "play" model also can reduce the multiple upgrades and updates that plague enterprise-wide or "Newspeak" solutions, says Frederico Fonseca, assistant professor in the School of Information Sciences and Technology (IST).

Too often, system designers aim for the "killer application" with the assumption that it will work well for every user and address every business or organizational need. But users are not homogeneous, and enterprise-wide or "Newspeak" solutions don’t take into account users’ different perspectives. The consequence: updates and upgrades are needed.


"For example, departments in banks interpret the term ’loan date’ differently," Fonseca said. "One department views it as the date when the loan was applied for, another when the loan was approved and yet another when the money was released."

Rather than forcing bank personnel to accept one definition, IT designers should create systems that can accommodate the different definitions. Such systems would have broad organizational use, thereby avoiding multiple systems or the "Tower of Babel problem."

"Users can interpret the same set of data differently, and systems need to be able to handle that," Fonseca said.

That argument is explained in a paper titled "Play as the Way Out of the Newspeak-Tower of Babel Dilemma in Data Modeling," presented by Fonseca and co-author James Martin recently at the 26th International Conference on Information Systems in Las Vegas. Martin is a professor emeritus of the Penn State psychology department.

The researchers draw on the work of several philosophers--notably Heidegger and Gadamer--to support their contention that "play" or back-and-forth dialogue between designers and users can reveal the subtle inconsistencies between users with different perspectives.

Sometimes the "play" yields a common understanding or fusion of views, and the IT designer’s job is made easier. Other times the dialogue leads only to acknowledgment of differences or inconsistent views.

"The communication itself is as important as finding common ground," Fonseca said. "Because fusion isn’t always reached, a successful IT system has to reflect inconsistent or incompatible views."

Designers also have to recognize that when users have difficulties with systems, users aren’t the problem. "User error" is a misnomer, Fonseca said. The problem occurs because the system is designed as "one size fits all."

Next for Fonseca and Martin is to apply their theory to developing methods for the design of information systems.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
