Objective
More time for installing the roof
Reducing the administrative process steps of roofers for more time on the roof.
The order books of german craft enterprises are full and it doesn't look like demand will flatten out. Doesn't sound like a need for transformation for the industry at first. But the dynamics of digital transformation are dragging new competitors onto the scene. Digital platforms are not only competing with the purchasing cooperative, but also with many small craft businesses that don't have time to worry about optimizing their administrative processes because there is too much to do on the construction sites. In addition, the new providers, such as meindach.de, offer the possibility of bypassing the three-stage distribution via the retail trade and buying directly from the dealer.

Approach
Rethink and adapt the role of the cooperative and its services in the change of digital transformations in a newly formed team.
Zedach eG decided to set up a digital team away from its day-to-day business. For this purpose, it called in the digital experts Convidera from Cologne, who not only acted in an advisory capacity but also provided premises and implementation capacities. This meant that ideas could be tested quickly and then moved on to realization. The initial contact with our target group was a bit bumpy for political reasons, but once we had our foot in the door, we were quickly able to find enthusiastic supporters from the trades.
Selection of work insights
Methods and techniques

Internship/Shadowing
The field of roofing was new to me. Therefore, it was all the more important to be able to look over the shoulders of some roof craftsmen.

Personas
At the beginning, I developed personas in a workshop with the project manager and secretary general so that the whole team could grasp our target group.

Blue Print
I captured the vision of the digital process between roofers, Zedach eG and the customer in a blue print. This served as a basis for understanding and development.

Google Sprint
A colleague and I ran a Google Sprint completely remotely because of Covid. In Miro, we were able to prepare and post-process the templates and workflows perfectly.

Visuals and storyboards
For communication with the Secretary General and to get the team in the mood, I created scribbles and storyboards.

Usability Tests
The click dummies were mostly created in Sketch. Most of them were then tested live. For this, we invited five roofers digitally or on site.
Insight into the software solution for roofing companies
Key-findings and solution approaches
Consulting without payment
Roofing trades have a large amount of time to spend on a (free) cost estimate without a subsequent job.
Renovation calculator
The renovation calculator (Sanierungsrechner) can be called up online by potential customers of the roofing company and provides an initial price estimate for the project after just a few clicks. It can also be used as a supporting tool in an on-site consultation.
https://flexbox.online/sanierungsrechner/Lack of documentation
Lack of site communication and documentation by roofing trades leads to occasional delays or even legal problems due to missing evidence. Construction site slips are often not submitted on time, are illegible or get lost.
Construction site management
The construction site management (Baustellenverwaltung) is the mouthpiece between the construction site and the office. Here, the current status of the construction site is recorded via cell phone and tablet with photos, text and voice messages. The time sheets can also be recorded via digital time recording.
https://flexbox.online/baustellenverwaltung/Digital invisible
Roofing companies often do not have an online presence and are therefore not only invisible to potential customers, but also to trainees and skilled workers.
Website builder
Modern design and customizable service descriptions give the craft business a digital presence with just a few clicks.

Learnings
Doing instead of asking
User feedback is not a "nice to have" but a "have to have" that is worth using at all levels. If exciting insights and thus effectiveness of humancentered design are shown, the approval comes by itself.
Promote transparency
All departments involved in a project must be picked up and pursue the same goals, so that no fronts or mistrust build up. Such a difference disrupts efficient and goal-oriented work immensely. Interdisciplinary teams and regular updates support common goals and transparency.
Depth instead of width
It is better to have one functioning product than five half-finished MVPs on the market. It is important to know and keep an eye on the value chain of the company. User feedback and analysis show directional possibilities and help to make decisions. Interdisciplinary teams as well as interdepartmental communication, e.g. in the form of workshops, then help to find consensus for the further strategy.
