What a company offers its customers has to fulfil several different needs, desires, constraints, which can originate from multiple different sources that affect the offering throughout its life cycle. All these criteria have to come together and be translated into statements that can support the designer's understanding of the offering's purpose. This translation is done through a requirements development process to provide a controlled process to define statements that describe what the offering is supposed to fulfil.This research provides insights on key challenges and success factors in requirements development to support the design of effective and resource-efficient offerings. Namely, it identifies crucial sources and aspects to be considered, and a requirements development process demonstrating how to overcome identified challenges. By getting the requirements right from the beginning, sub-optimisation and unnecessary time and risks can be avoided.The consideration of accurate sources and aspects is considered to be one of the most important factors for the successful design of offerings. It is also in the earliest phases of design, that is to say requirements development, where one has the greatest possibility to affect the environmental impact of the offering. What is missing, however, is sufficient and appropriate support in industry on how to do so.

APPENDED PAPERSThe following papers were written during the research and set the foundation for this thesis: Contributions in the papers:Paper 1: The author of this thesis solely carried out this review (Systematic Literature Review 1), and the paper was to about 95% written by her. The co-author supported in the research process and supported with background knowledge in the area, framing and scope.Paper 2: This paper was prepared in collaboration between the authors, from idea to submission. Each author contributed with cases as well as knowledge from their own expertise. The author of this thesis contributed specifically with the idea to focus on SMEs, and also added the sustainability aspects of providing integrated offerings. The author of this thesis also contributed with one of the use cases (that originated from Interview Study 1), and wrote about 30% of the text in the paper.
Paper 3:The literature review and the company cases were based on results from Systematic Literature Review 2 and Interview Study 1. The author of this thesis wrote the main draft of the manuscript. Co-authors supported the work along its process, and especially with rewriting and reworking when revising the paper after the first submission.
