    This study examines the possibility to improve an in-house software development process by applying the ISO standard (ISO 9241-210 Human-centered design for interactive systems) in the development of an Enterprise Resource Planning (ERP) system. The detection of improvement is achieved by comparing the levels of Usability Maturity Model (UMM) and Capability Maturity Model Integration (CMMI) before and after applying the human-centered design into the software development process. The study also aims to define a suitable set of usability methods, which can be both attached to the in-house software development process and used to identify possible cultural differences in the usage of the ERP system. In this thesis, a set of usability methods are combined with the human-centered design activities. After this, a process of the ERP system is examined by applying the principles of human-centered design and usability methods. First, a subset of methods is used to understand and specify the process's context of use and the user requirements. Second, mock-ups and a high-fidelity prototype are created to produce design solutions to meet user requirements. Finally, the created designs are evaluated against the user requirements by applying a subset of evaluation methods. Some of the usability methods enabled the identification of usability issues and requirements, as well as cultural differences in the system usage. Applying the methods to the software development process improved the system usability. For example, the results of System Usability Scale improved significantly compared with the current system (SUS score approx. 50/100) and the prototype (SUS score approx. 74/100). The study produced recommendations about the applicable usability methods. However, the main result of the study is a conclusion that the Usability Maturity Model and Capability Maturity Model Integration levels can be increased, and thereby in-house software development process can be improved by applying the human-centered design activities and usability methods.
