Discovery, Definiton & Concept

Service Level Agreement (SLA) modelling refers to the process of designing and defining Service Level Agreements (SLAs) between a service provider and its customers. SLAs set expectations for the quality and availability of IT services, and provide a metric to evaluate the service provider’s performance.

The SLA modelling process includes identifying business requirements, defining service quality indicators (SLIs) and setting service targets and guarantees. It should also consider the operation of the service and the monitoring and review of the SLAs in this process.

Good and effective SLA modelling leads to better communication between the service provider and its customers, while avoiding misunderstandings and potential conflicts. It enables the transparent presentation of the service provider’s performance and creates the foundation for a trusting and cooperative partnership.

Open source versus proprietary refers to the choice between software solutions that are provided as freely available open source software (OSS) and those that are provided as vendor-owned or in-house proprietary software (PS).

Open source software is software whose source code is freely available, improved and supported by a community of developers. OSS usually offers greater flexibility and customisability, a greater number of features and a lower cost point than proprietary software.

Proprietary software is software that is protected by the developer as intellectual property and whose source code is not freely available. Proprietary software usually offers higher security and better support from the developer, but also higher costs and less customisability.

The choice between open source and proprietary software depends on the needs of the organisation and the purpose of the implementation. A thorough review and evaluation of both options is required to find the best solution for the company.

During the concept and design of a suitable digital solution, solution design describes the process of analysing the initial situation, defining the exact requirements and the basic review of all available options. During solution design, different disciplines, such as business analysis, architecture or security and data management, have to work closely together to ensure that the solution meets the business needs while being technically feasible. However, it is important that the solution design itself is reviewed periodically to ensure that it is always up-to-date and relevant.

Product selection is the process by which a company chooses a particular product from a variety of options to integrate into its business model or to replace an existing product. This process takes into account several factors, such as customer requirements, market trends, competitive analysis, technological capabilities and financial considerations. Thoroughly reviewing the available options and weighing their pros and cons helps make the best decision for the company.

Requirements Engineering is a systematic process for collecting, analysing, specifying, verifying and managing requirements for a product, service or system. It aims to ensure that requirements are clearly defined and understandable to enable successful implementation.
