Oral Hammaslääkärit is Finland's best-known and the most popular dental service company, which provides serves almost in 80 clinics nationwide. The oral health care services provided by Oral cover all specialties.

Integration of patient information system

In 2018, Oral Hammaslääkärit Oyj acquired private oral healthcare businesses owned by Med Group. Med Group Hammaslääkärit Oy, which operated under the brand 'ONNI hammas', had 22 dental clinics in 15 locations in Finland. The aim of the project was to integrate the patient information system of 'ONNI hammas' clinics into Oral's system and to develop technologically advanced services also for new customers.

The ownership and overall responsibility for the project belonged to Oral's integration manager. The technical project manager for the critical IT integration was selected from Graniitti Services Oy, which provides experienced professionals for various project needs.

Flexibility, commitment and cooperation

"We are very pleased with how the big integration project was completed according to plan, tight schedule and budget", says Jarno Huurinainen, CEO of Oral Hammaslääkärit Oyj.

“From the very beginning of the project, commitment and the ability to cooperate with both Oral's own organization and the supplier were seen. Of course, there were small surprises during the project, but the project manager adapted well to the changing needs of the project. ”

“Communication went great and our organization was regularly informed about the progress of the project”, thanks Anna-Liisa Vuorinen, Integration Manager of Oral Hammaslääkärit Oyj.

Arek builds, maintains and develops common information system services for pension insurance. Important issues for Arek are the high availability of system services and risk management, as well as cost efficiency.

Application hosting transition project

Arek's need was to transfer the application management of critical systems from another supplier to a new supplier and find a reliable and competent project manager.

When the Granite Service expert acted as the transition project manager, the project stayed on schedule and within budget and the goals agreed at the beginning of the project were achieved 

The key to success was close cooperation between the supplier teams and the customer organization and active steering group work. The project got the parties to invest in achieving the goals of the transition and in the seamless operation of Arek's information system services. 

We also work on the Arek project, where the data center-based, mechanical control background system was transferred to the cloud service. At the end of the project, as a technical project manager, we ensured a smooth implementation where all ancillary work was taken into account and risks were managed. The project maximized the quality of the content of the end result, through the transparency of the parties and smooth cooperation.

Katja Koivu-Pirhonen, who acted as project manager, was professional, resistant to pressure and was able to hold the reins in her hands, even in tight situations.”- says Satu Koskinen, Arek's IT Director
