Guaranteed level of support (SLA - Service Level Agreement) for applications, portals, and websites, as well as online stores.

We provide guaranteed support services for both applications we have created and those designed by other contractors.
At the client's request, we can join the project at any stage or complete the assigned tasks.

Example stages of work related to starting the provision of SLA services

If we undertake to support a project (with a specified level of availability)
implemented by another contractor, the order of work usually includes:

01
Signing a contract (including NDA, GDPR compliance).
02
Providing access to communication/ticketing tools (Jira/Slack) by VISUAL.
03
Providing access to a test version of the application and the repository by the client. In case the project does not have a repository (e.g. Bitbucket), we will create and configure it, connecting the development environment with the repository and the testing/production environment.
04
Code analysis and project documentation review.
05
If the project does not have post-execution documentation, our team will prepare it (in the scope necessary to understand the processes, dependencies, and applied technological solutions). The documentation becomes the property of the client.
06
Performing security tests (such as penetration testing) to assess the current security status of the system. In situations where the application is a critical component of the infrastructure, security testing is an integral part of taking responsibility for the supported system/application.
07
Execution of functional and non-functional tests within the most important elements of the system (load, integration).
08
Report from tests (recommendations for changes).
09
Starting to provide SLA services as agreed in the contract. Monthly reports on the performed work are prepared for each month of the service provision.
