Commissioner: STIHO


Stiho is a supplier of construction, wood and plate materials. Costumers of Stiho are construction companies active in building, renovation and the development of small new building projects. Craftsmanship and knowledge about product and application modes are disappearing rapidly in the Dutch construction industry. Ageing is the main reason for this development. The loss of knowledge and skills is already causing problems in maintaining the quality of project in this industry. The question is how these skills and knowledge can be preserved and circulated to future generations through digital storytelling? The target group that Stiho wants to reach consists of construction companies active in building, renovation and the development of small new building projects. The media application that has to be developed must make this knowledge accessible to craftsmen at the ‘Stiho-building square’ (together with the Giebels formula) and at building locations.

Concept Evaluation

On Wednesday, the 17th of april we conducted a concept test in Haarlem with Rik and Jasper, two contractors who had earlier helped us out at the co-creation workshop. We started by explaining our concept via Protosketch. Linda explained all the features involved in the app and we gave them some time to reflect on it.

Some refreshing thoughts from the discussion that we should take in account:

– Consider implementing a commercial goal via the contact list.

– Implement location in the contact list so you can see if anyone is in a nearby location

– Stop focussing on plumbing and such professions. Only focus on STIHO and their field of expertise.

– It’s interesting to let all the STIHO customers be part of the contact list. If this works you get a ‘jew based model’. Keep all the work within the STIHO community

– Consider rating people on their expertise

– In doubt whether the users would really use the archive or if they’d use different channels (like Google or catalogues for this kind of stuff)

– Might be interesting to create a group within the app for each project your working on so you have all your under-contractors in one list.

– The app has got a major recommendation function

Card Sorting

A second part of the concept test involved card sorting. With card sorting we tried to get a better grip on how construction workers will search through the archive and what kind of catagories we should make.

Some of things we should to take in account are:

– Take a look at STABU when creating categories for the archive

– Contractors will use different terms than DIY’ers or big companies like BAM.

Both Rik and Jasper were really helpful and gave us great new energy and insights to finalize our concept. They were really enthusiastic about our ideas and they could imagine using this app. Also they thought it had a commercial advantage for STIHO.
