    By means of qualitative research methods, this dissertation develops new knowledge of co-working spaces in the concext of workplace management discipline, more closely distributed workplaces, and workplace usability. The perspective of workplace development whereby the workplace is seen to be distributed across the city has become increasingly common within both workplace practice and research since the first decade of the 2000s. Additionally, the roles of workplace usability and user experience as central concepts related to the development and operation of facilities have become more generalized. The concept of co-working space is one of the newest and globally most common multi-tenant office concepts to have evolved in order to support new ways of working. It has influenced the workplace user demands and thus challenged today's workplace providers to create more attractive, hospitable and user-centred workplaces if they are to be successful. Initially, co-working spaces were born to support collaborative and mobile working habits of independent workers by offering attractive and flexible workspace with community. Later, co-working space concept has been applied versatively and extensively to all kinds of workspaces. The concept of co-working space remains a somewhat new research area. Thus, related  knowledge of distributed workplace needs to be aggregated. While attractive service is the key asset of co-working spaces also workplace user experience related research is topical. The findings of this study builds on prior discussions about distributed workplace locations and placement of co-working space among it, as well as those concerned with the evolution and typology of co-working spaces. Current workplace usability and user experience discussions is advanced by investigating how co-working space concept meets users' expectations of their future workplace, as well as by illustrating the desired user experience of a successful co-working space. On a practical level, this dissertation develops understanding of the co-working space concept as well as means to include user experience viewpoint to workplace development.

    Supplier evaluation and development in construction: data-driven analyses
    (Aalto University, 2021) Noorizadeh, Abdollah; Kuosmanen, Timo, Prof., Aalto University, Finland; Rakennustekniikan laitos; Department of Civil Engineering; Operations Management in Construction; Insinööritieteiden korkeakoulu; School of Engineering; Peltokorpi, Antti, Asst.

    This dissertation studies the buyer's perspective on supplier evaluation and development within construction supply chain. Highlighting the multitude of suppliers in a construction firm's supply chain and the fragmented nature of the sector, former research emphasizes the essential role of implementing effective supply chain management (SCM) in construction industry. Extending this notion, adopting successful practices of supplier evaluation and development from other research and industry domains can be very beneficial to this sector. Thus, this study develops data-driven methods for supplier evaluation and development in construction using performance evaluations and purchase transaction data. The analysis involves data from suppliers that work for a large international construction firm and operated in Finnish construction projects during the period of 2010–2016. First, it is argued that supplier evaluation in a changing construction project environment differs from evaluation in the context of routine-based operations, such as manufacturing. Challenges with supplier evaluation in the context of construction projects are outlined, and a possible solution from the data envelopment analysis (DEA) context is developed and discussed. Next, it is suggested that combining DEA with the recency, frequency, and monetary value (RFM) concept and customer pyramid from marketing literature can improve supplier development (SD) investment efforts in construction. For effective SD resource allocation, suppliers are categorized based on the scores obtained from the applied framework. Then, building upon earlier research on productivity dynamics in economics and real options theory (ROT) for strategic investments with uncertainty, this work claims that there are certain patterns between the obtained supplier performance and the purchasing volume of the buying company. The study proposes that suppliers be categorized into exiting, surviving, and entering groups based on the discontinuity, continuity, and start of the buyer's purchase, respectively. This method can differentiate the influence of each supplier group from the company's supply chain performance. Finally, this study investigates supplier evaluation within the project lifecycle by testing whether the construction firm favors suppliers from the late or early project phases. Overall, this dissertation contributes to research on supplier evaluation and development by extending and presenting novel data-driven approaches in the construction supply chain context. For practitioners, the study provides effective methods to manage large supplier networks and evaluate strategic decisions to develop supplier portfolios over time.
