Abstract [en]

Purpose – This study maintains that there is a need for proper execution of coordination mechanisms as a means to reduce waste. The purpose of this paper is to explore the relationship between the coordination of activities and resources on the one hand, and the occurrence of different types of waste on the other.

Design/methodology/approach – The empirical context of this paper is a case study at a Swedish construction company that has applied the industrialised housing concept; a concept which has increased in popularity in recent years. The core concept of industrialised housing means that houses are (more or less) pre-manufactured in specific production units, i.e. factories, and thereafter assembled on-site.

Findings – The analysis highlights the importance of having the right type as well as the right amount of coordination. In addition, obstacles and challenges for proper coordination are discussed.

Originality/value – Even if not all waste can be explained and eliminated by appropriate coordination, this research shows that coordination theory provides lean researchers with a new tool for analysis of the supply chain and how waste can be eliminated.

Abstract [en]

To satisfy customers’ desires with a maintained efficiency of the production process is a challenge for many house construction companies. Houses are one-off projects with a production process characterized by variability and complexity that often lead to unpredicted costs. Prefabricated component solutions could possibly solve these issues through modularization, mass customization and delayed product differentiation. The purpose of this paper is to explore the opportunities and barriers to use prefabricated house components. Interviews were conducted with two industrial house manufacturers to pinpoint these opportunities and barriers. The impact of this research may have value for house construction companies considering the use of prefabricated house components. The use of these components may lead to benefits such as shorter lead-time, higher quality, decreased complexity in coordination and reduced risks of production failures. Moreover, this research may be valuable to house component suppliers in the business development of their product offers to industrial house builders.

Abstract [en]

The kitchen is the heart of the house where people spend much of their time. It is, therefore, an important room that requires high quality. Because construction is argued to be unproductive and wasteful with low quality, studying a kitchen assemblage in detail is of particular interest due to its complexity with many details. In lean, the visualization and transparency of processes is the core for waste reduction and improvement. Low productivity levels are often argued to depend on a lack of information about the root causes of process problems. Thus, more information about the installation process of kitchens by studying the process is needed to target the sources of problems in terms of waste. The purpose of this paper is to gain a further understanding of how value stream mapping can be used to identify different types of waste that occur when acquiring and installing kitchens. Value stream mapping is carried out through observations and interviews at an industrialized timber house manufacturer. Data analysis resulted in information about inconsistencies in the kitchen installation process, i.e. the root causes of costs and delays for the entire housing project.

Abstract [en]

The purpose of this thesis is to describe and analyse purchasing strategies and their interdependence with the production process and supplier relationships in industrialized housing. The thesis is a multiple case study of four Swedish industrialized timber-housing manufacturers. The case studies included interviews with top managers concerning purchasing, production and supplier relationships. Production is considered the heart of the company. Therefore, to gain an in-depth knowledge of how production affects purchasing and thus supplier relationships and vice versa, observations were made to study the production process. Many different parts and competences need to be coordinated in the creation of a house. In the West, the construction industry has been heavily criticized for low efficiency and effectiveness. Conclusions from the case studies showed that codevelopment, customization and secure deliveries are regarded highly by industrial house builders and to obtain them, long-term relationships with suppliers are preferred. Industrialized house builders are argued to have more long-term relationships with their suppliers than traditional on-site builders. Industrial house builders choose their suppliers based on the purchased products’ value-in-production rather than price. Product and process innovations created in collaboration with suppliers seem to be a way to enhance the production process of houses. Through the site resource of the factory, industrial house builders have the potential to refine their processes in win-win partnerships with suppliers for a more efficient and effective production of houses, as onsite work is harder to standardize and control.

Abstract [en]

Purpose - This article hypothesises that value-driven purchasing of customized kitchen cabinets is more profitable than market-driven purchasing in industrialized housing construction. The hypothesis is examined through a case study of kitchen carpentry at one of Sweden’s largest producers of industrialized prefabricated multi-storey housing. By comparing characteristics of market-driven vs. value-driven purchasing, this article aims to further clarify the benefits and drawbacks of these two strategies.

Design/methodology/approach - A theoretical framework is proposed by comparing characteristics of market-driven vs. value-driven purchasing that clarifies the benefits and drawbacks of these two strategies. An explorative case study of kitchen carpentry at a house manufacturer illustrates purchasing of kitchen cabinets in the industrialized housing industry in relation to the proposed framework.

Findings – According to the case study, from a value perspective, a long-term relationship with a dedicated local, smaller supplier is a preferable choice over a short-term bulk supplier, even if the short-term supplier has (much) lower prices.

Research limitations/implications – This is a single-case study that should be verified by further empirical work of a test-delivery from the local sub-system manufacturer. Such a study would provide more insights into this area of work and make it possible to thoroughly evaluate potential risks. The indicative results in this paper can be made conclusive through quantification of the proposed Lean purchasing characteristics.

Originality/value – A comparison of value-driven and market-driven purchasing is carried out in theory and applied to a real case study that brings new perspectives to purchasing. In this way, the article proposes alternative purchasing strategies to the construction industry.

Abstract [en]

The purchasing strategies in the construction industry have been considered by many writers in construction management as short-term and arms-length. However, a different picture is portrayed in the manufacturing industry, where the purchasing strategies are mostly long-term to secure supply for production. Industrialized building is at the crossroad between construction and manufacturing, which raises the question of what purchasing strategies are applied. The purpose of this study is to investigate how the Kraljic model (1983) can be applied in an industrialized housing factory. The purchasing strategies were studied through interviews with the CEO of a timber housing manufacturer in northern Sweden. Industrialized housing manufacturers can take advantage of standardized construction systems and secure production flows that eliminate waste and improve quality. Evidence proves that long-term relationships similar to those in the manufacturing industry also exist in the construction industry regarding factory production. The analysis of these strategies suggests that the total product offer, including logistic services, plays an important role in choosing supplier.

Abstract [en]

In economic and management literature, the relationship between supplier and buyer can be more or less intimate. It can vary from market-driven with a constant change of suppliers to a value-driven relationship with one sole supplier. Purchasing strategies of construction companies have often been described as short-sighted, where price is the most considered aspect. Recent lean management literature promote value-driven purchasing, since it provides benefits such as just-in-time delivery, zero defects and customized products through close technical collaboration. This article hypothesises that value-driven purchasing of customized kitchen cabinets is more profitable than market-driven purchasing in industrialized housing construction. The hypothesis is examined through a case study of kitchen carpentry at one of Sweden’s largest producers of industrialized prefabricated multi-storey housing. By comparing characteristics of market-driven vs. value-driven purchasing, this article aims to further clarify the benefits and drawbacks of these two strategies. At the case company, kitchens are ordered cabinet-by-cabinet and then installed inside the factory. The company is considering the possibility of a long-term relationship with a smaller local supplier that can deliver a new kind of innovative kitchen cabinet solution that is prefabricated. If the local supplier can meet the expectations of just-in-time delivery, zero defects and a product “tailor-made” for the housing company, there is much to gain.

Abstract [en]

The specific topic of innovation in construction has only recently been given as much attention as in many other sectors. In the realms of lean production, much literature points out that the peculiarities of production in the construction industry lead to variability and thus waste and low performance levels with respect to productivity and value to clients. Innovative component solutions could possibly decrease the variability and complexity and therefore solve these issues. The purpose of this paper is to illustrate some potential areas where innovative house components could possibility decrease construction complexity and create a leaner construction process. A case study was conducted to collect data from bathrooms and kitchen installations at a house construction company. The impact of this research may have commercial value for suppliers, since they often are the drivers of innovation. The social impact of the research is to highlight problem areas that can enhance the final product for endcustomers. Enhanced system design may also contribute to greater production efficiency and reduced waste, leading to a lower impact on the environment.

An analysis of these strategies suggests that the total product offer in terms of customization, including logistic services, plays an important role in choosing a supplier to satisfy the needs of efficient production. A new model is developed regarding the effectiveness of the purchasing strategies on the production process, where products are classified according to value-in-production instead of their monetary value.
