UI / UX design

In order for our applications to provide the best possible experience for their users, impeccable technical implementation is not enough. We place great emphasis on designing the user interface, user experience, and user processes. In this way, we help to implement the solutions imagined by our customers in such a way that they offer as much as possible not only in terms of functionality, but also in terms of software ergonomics. Our work supports the user to see, manage and assist in the development of streamlined processes in even more complex systems.

The contribution of UI / UX design appears in different forms at every stage of the development process of the solutions we have developed individually. In the survey phase, as active communication with the customer, which later forms the wireframe of the application.

The wireframe depicts the logical structure of the application, which undergoes even smaller or larger changes as a result of negotiations with the customer, depending on how mature the demand specifications are. This is because the wireframe is an excellent tool for visualizing the expectations for the operation of the application, which can often shed light on additional latent needs.

After creating the wireframe, we create a prototype of the application using a Figma or Adobe XD tool. Even during prototype production, we pay close attention to creating a process experience so that the customer can already get a taste of the experience they want to provide with the intended application during testing.

After fine-tuning together, the final design and UI layouts (user interfaces) begin. When designing, we place great emphasis on ensuring that the completed development fits into the existing corporate image. During branding, we not only place company logos in the application, but also design custom icon sets. Our design UI specialists are always up to date with the latest international trends, so the developments we make are not only technologically competitive but also in terms of design.

The UI / UX design is more than simple graphic elements and well-placed nicely drawn logos. This gives the user experience, which will make the app lovable. With a well-thought-out and planned development, you can increase user satisfaction, efficiency, and a long-term solution for your business.

Cloud migration

M365 migration

At Grepton, we are aware that telecommuting is becoming more and more a part of everyday work today. Switching to this requires serious professional training and care. That’s why we provide effective assistance to our partners and ensure that the migration of email systems goes smoothly and successfully during the transition to online teamwork in Microsoft 365.

Through our service, we support the migration of on-premise mail systems to Microsoft O356 Exchange Online. As part of this process, we will migrate some or all of the data found in the on-premise mail system to O365 in the Microsoft cloud.

We help you migrate the following data:

  • user mailboxes and their contents,
  • user calendars and their contents,
  • user contacts and their contents.

Exchange Online is only part of the Microsoft O365 family of products, which, depending on the package you choose, allows you to take advantage of additional services and applications:

  • Office products (Outlook, Word, Excel, PowerPoint, Publisher, Access)
  • Teams teamwork and collaboration service

License Management

Our partners not only get licenses, but a complete service. With us, the partnership begins with reviewing and optimizing existing licenses to find the unique license combination that best fits our client’s business needs.

During the optimization process, we take stock of the licenses that have already been purchased and subscribed. We then use the profiling process to assess and learn about the individual needs that arise from day-to-day operations. Finally, we provide a documentation that includes our suggestions for the appropriate license structure.
We optimize not only the number and type of licenses, but also the performance of the resources used in Azure. Where power consumption, outliers and weak points are monitored. After that, we make a recommendation to optimize your Azure subscription. It is often the case that we are already able to achieve cost savings by switching to a new type of server resource while maintaining current performance.

Deployment, training, and ACM (Adoption Change Management) are also part of our services, so you can take full advantage of your licensing.
In the field of our licenses, we can serve our customers with a flexible subscription structure. With this structure, even day-to-day changing business needs can be met, new licenses can be obtained in a matter of seconds, or redundant ones can be eliminated. Payment is available based on actual consumption in monthly or yearly periods.

Most common license groups

M365 : You can find different combinations of the most common Office applications in the M365 packages. You can find everything you need to have a digital office, from correspondence through file sharing to group collaboration.

D365 : Innovative, intelligent business applications that cover the entire business process. With a high degree of synergy to the entire portfolio of Microsoft products

Azure: A flexible cloud-based computing platform with endless possibilities.

Change Management (ACM)

In the implementation projects, we not only strive for integration, but also place great emphasis on adoption and change management. Our goal is to achieve a high degree of acceptance among employees for the solutions we introduce. This will help them to truly become part of the corporate culture and achieve the change they want.

In the case of successful implementation projects, in addition to application integration, special attention must be paid to making the new application part of the corporate culture. If both of these focus points are realized, we will be able to achieve the goal of introduction.
In projects where the project goal is not achieved, the reason for failure can be identified in 70% of cases as inadequate or non-existent change management. In such cases, the new application is implemented at the enterprise level, but this is not done at the individual level, so the project is not able to trigger the desired change. If we make up for this in retrospect, the time and budget will be exceeded and the effectiveness of change management will be affected.

At the Grepton Group, we use the ADKAR methodology developed by Prosci to support change management in our implementation projects. The philosophy of change management is also present as an integral part of our project management. For those implementations where there is a need for change management, our ADKAR-certified consulting colleague is actively present from the very beginning. They make sure that we keep increasing the acceptance and knowledge among our employees in parallel with the integration process.


Want to know more about ADKAR?

The ADKAR methodology consists of 5 main stages, which together during the implementation process achieve what is already part of the corporate culture by the time the application integration is realized.

  • Awareness: Raising the awareness of the arrival of the new application.
  • Longing: Build a desire for the app in prospective users.
  • Knowledge: Equip users with the knowledge required to use the application.
  • Ability: Transforming knowledge into a skill.
  • Confirmation: Ensure continued use of the application.
