is offered by the tool, the degree to which a project-specific process model can be defined can also be considered in this view. 9.5.5 Provider View Market position of the manufacturer and support offered The provider view considers the market position as well as the different services that are offered by a manufacturer. When choosing a tool, not only the functional aspects but also constraints that must be fulfilled for the tool to be applicable are pertinent. The degree of brand awareness, for instance, and the reputation of the provider are therefore often used as decision cri- teria. Due to the relatively high acquisition cost and the long-term sub-

9.6 Summary 147 scriptions to support services, a close commitment toward the provider is made. 9.5.6 Technical View The tool’s ability to perform and to integrate The technical view involves technical context conditions that the system is expected to meet. Important aspects in the technical view are, for instance, the ability to integrate the tool, the performance of the used repository, the necessary hardware and software, and scalability of the tool. The ability of the tool to integrate can be determined, for instance, by investigating to what extend the functionalities of the tool are accessible via an API and to what degree the process, data, and control integration is possible. The scal- ability of the tool can be determined, for instance, by determining the max- imum number of users that can be maintained or the maximum number of objects (e.g., content packages or documents). The performance of the repository used can be measured by determining the degree to which importing and exporting data can be done as well as by determining the performance of the query interfaces or the available security concepts. 9.5.7 Economic View Introduction and follow-up costs The economic view regards the possible costs that arise due to the acqui- sition, introduction, and maintenance of a tool (e.g., licensing costs, employee instruction costs, and support costs). The amount of the relevant costs can consist of the integration costs, costs of operation, maintenance and infrastructure, costs for method tailoring, and acquisition costs. 9.6 Summary When managing requirements during requirements engineering, it is nec- essary to store the information in a way that the quality criteria for require- ments management are met. Tools support the requirements engineer in doing so. These tools can be differentiated into professional RM tools, modeling tools, and standard office applications and differ from one another in the functionalities that are offered to the requirements engineer. This is the reason an evaluation must be done before a tool is selected, so as to not inhibit the introduction process unnecessarily.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
