  A plan in the making should pull from what creates customer value and from the performers' knowledge and understanding of the context. A plan for commitment should represent the customer's intent in a way that calls for action on the intent's behalf. A promise to commit to a plan happens at many levels and in many forms toward execution, and every promise made becomes a push mechanism to keep that promise. Since a plan represents both push and pull around a commitment, knowledge about these mechanisms can help to understand a plan's function. The main contribution is a reflection on how a plan's push for commitment interacts with emergent situations and an analysis of what part of the commitment is within or outside the scope of the promise and the promiser's influence and control. The promise made committing to a workplan as input to a Percent Plan Complete measurement is used as a practical example. The paper's conclusion arguably strengthens many of the existing parts and principles of the Last Planner System but also gives suggestions for improvement.

  The paper is conceptual, with the aim of raising a new debate on complexity and value creation within IGLC. The topic of complexity in construction projects was first raised in the Nineties before it in the early 2000s was introduced on the Lean Construction and IGLC agenda. When facing a complex problem, there are two possible strategies to pursue with reference to the Cynefin framework for complexity. The first is to transform and move the problem into the complicated or even simple domain, thereby making it manageable. The second is to handle the problem within the complex domain. The dominant approach within both Project Management and Lean is the first, namely, to emphasize efficiency, flow, standardization, best practice, planning, reliability, and control. The paper challenges this lop-sidedness by pointing out its potential reductionism and argues that we should also appreciate, exploit, and take advantage of complexity instead of just combatting it. Value creation is reliant upon both strategies and is therefore not a question of either or, but of balance and trade-offs based on an inherent dualism.

  Lean construction has inspired the AEC industry globally over the last decades, and this manifests within a wide array of contexts. The purpose of this paper is to provide a narrative-based qualitative analysis of the emergence and impact of Lean construction on a national level, notably in the Norwegian AEC industry. The analysis is based on the concept of paradigm shift and on empirical knowledge in the form of narratives. The narratives of practitioners and researchers provide deep insights into how Lean Construction has inspired the Norwegian AEC industry and academia, respectively. The reflections indicate that the introduction of the Lean construction principles and tools in the Norwegian AEC industry has depended on promoters who have been convinced about its advantages. The role of active promoters – in particular Dr. Glenn Ballard – is underlined as key to successful introduction of Lean Construction. Key cultural features of the Norwegian AEC industry are emphasized as important success factors. Lean Construction in Norway needs to be understood as a phenomenon occurring within a setting that is generally advantageous but also following an effort carried out on several levels. Key elements that can be used within other contexts are (1) the existence of promoters, (2) cooperation between industry and academic circles, (3) a high degree of trust and (4) a predominance of bottom-up organizations within the industry with few levels of hierarchy.

  Principles can carry the intent from the theory they represent. Military strategy has a long history of being presented through principles of war. In Lean Construction, principles like “flow,” “pull,” “remove waste” are used with ease. However, have they been correctly treated and understood? Supported by a literature review, we follow the use of principles through the history and the standing and character they have gained. The work is grounded in the important position of principles between theory and practice, and methodologically proceeds through philosophical conceptualisation. We recognise the guiding, dynamic, adjustable, durable, action-oriented, prescriptive and descriptive capabilities of principles, and emphasise their important capacity to facilitate abductive reasoning. We call for reflection upon the power of principles to strengthen the theoretical conceptualisation of Lean as well as upon their power to support improvement in practice.

  The construction project being studied is a government investment related to the relocation of a biomedical institute delivering research-based knowledge and contingency support in the fields of animal health, fish health and food safety. The project covers a total of 63,000 square meters distributed over 10 buildings with a very high degree of complexity. The design alone has required 1 million hours, which relates to a client cost of about 100 million Euro. The purpose of this paper is to study the applied methodology for managing the detailed design to identify lessons learned from the project. The theory underlying the study is inspired by lean design management and design theory linked to design as phenomena, including reciprocal interdependencies, iteration, decomposition, design as a “wicked problem”, learning, gradual maturation, etc. The article is based on an abductive research design and has been implemented as a case study where both qualitative and quantitative methods have been used.

  The purpose of this paper is to develop an analytical model for further verification of design and engineering as processes of learning. Such a model should in particular be able to uncover that design projects mature progressively through interactive processes with strong reciprocal and sequential dependencies. We assume that the linear waterfall style of project management for design and engineering is not adequate for coping with the nature of design and engineering. Following the verifications, the next step in this research is to develop a model for improved design management. The paper addresses the nature of design and engineering and learning theory, and contributes to an improved understanding of the phenomena in question.

  In the modern engineering environment design projects have become increasingly complex; this calls for an updated perspective on how to plan and coordinate design projects. This paper describes the identified premise that will lay the foundation of the development of a model for planning and controlling such projects. The premise includes principles, requirements, and methods derived from theories around subjects, such as, production theory, lean and agile. The distinctiveness of the design process has been central when setting the premise for the model.

  The Last Planner System (LPS) is widely characterized as a pull system. In this paper the authors question if this characterization is correct. The authors argue that LPS applies a combination of pull scheduling and push control at the shop floor level. Line of balance and Takt-time Planning are also discussed. There are no findings that support that these techniques applied in combination with LPS change the authors’ main conclusion. The goal of this paper is to provide a better understanding of LPS and to contribute to the discussion of pull-push. The authors agree that pull may not always be the best option. The authors argue that choosing pull, push or a combination of the principles should be based on the production dynamic in question.

  The purpose of this paper is to shed light on the feasibility of using waste drivers to explain waste in a design and engineering setting. Waste drivers are defined as the mechanisms that have the capacity to create waste, under certain conditions. The waste can occur in design and engineering, and as a consequence of design and engineering. Waste include, e.g. reduced build ability and usability, with increased costs, time, and quality. The distinctiveness of the engineering process has been central when attempting to identify the waste drivers. The complexity associated with waste in design and engineering may indicate that the conventional manufacturing wastes do not suffice in the context of identifying waste in design and engineering. Based on researched literature and a case study, a list of waste drivers was identified. This paper should contribute to the understanding of design and engineering processes. Thus, potentially making design and engineering processes more predictable.

  This article sheds light on key factors associated with innovations that are mainly based on experiential learning. The history of a company engaged in the offshore oil and gas industry exemplifies the points: Hitec started out as a small company with limited financial resources, but over a 10-year period, its innovations and improvements radically transformed offshore oil and gas drilling operations. An evolutionary methodological approach is balanced by theoretically informed analysis. A main finding is that customer–supplier interaction was crucial. Hitec’s success, crowned by its eventual acquisition by American capital, can be attributed in part to the knowhow and technology provided by one of its suppliers and partners during the early phase. However, it has also depended on a series of other factors: a flexible, motivated and creative organisation; targeting of the right knowhow; being part of a cluster and thus enjoying easy access to important customers and suppliers as well as easy, informal flow of ideas and information; developers and entrepreneurs prepared to take risks; being in the right place at the right time; a good measure of luck; the underdeveloped state of American drilling control technology; Norwegian oil and gas policies supportive of domestic technological companies; and proximity to research labs which were conducting full-scale tests of drilling operations. An invention made by regional researchers can also be linked to Hitec’s innovation of a drilling control system. The relevance of the article is its contribution to a better understanding of the complexity involved in the implementation of major practice-based innovations – a process which includes identifying and creating ideas; finding a market/customer and putting the ideas into practice.

  Applied to continuous improvement work in a construction site setting, a way to operationalize workflow measurement in the construction industry is proposed in this paper. Our conceptualisation uses the metaphor of a river. This river flows with a certain smoothness, intensity and quality (more or less turbulently). The water represents the man-hours available to the employer – which are divided between productive work (direct work, indirect work, planning and HSE work); and waste (e.g. rework, waiting and other forms of downtime). We distinguish between observable and hidden waste. Hidden waste is tied to the potential improvement of methods used in transformation work and indirect work. Our conceptualisation draws on the OEE (Original Equipment Efficiency) concept from manufacturing. For practical reasons, work intensity is assumed constant. Thus the work pressure is even, but the tasks are not necessarily productive. Observable waste, except rework, relates to the smoothness of the river; rework relates to its quality. Flow was measured through observations and self-reporting. All workmen involved in a construction project over time, e.g. for one week, fill in a form estimating their time use, including the daily time loss and its causes. The principle is to detect “making-do” and other sources of waste or downtime. Suspecting that a time ratio cannot produce enthusiasm whereas time reduction can, low values for wasted time are to be interpreted as good flow. Sufficient data validity depends on staff training and motivation. A period of measurement culminates in a joint meeting with the workmen. This is where continuous improvement comes in. Results are discussed, efficiency improvement measures identified, and action plans prepared. Later, e.g. another two months into the project period, new measurements are made, and the figures are followed up with reflections about further improvements.

  Our focus in this paper is the design of LPS-inspired planning processes in engineering in a case taken from the mechanical offshore oil and gas construction industry. An integrated project engineering delivery system based on design and engineering theory is presented in the paper. Our conceived operationalization is based on a combination of traditional rationalistic models and iterative and inclusive approaches like the ones found in the Last Planner System. The developed model is being tested out in a company setting in an ongoing study, and what are presented here are our preliminary findings. We have uncovered a need for considerable changes, above all to the phase plan and lookahead plan, both of which need radical rethinking to be applied in engineering. Limiting the phase planning timeframe to a few weeks, focussing on detailed milestones based on different levels of maturity in the engineering knowledge that emerges is suggested. A significant finding is that within engineering, it often seems necessary to rely on “making do” as a way of working; hence, the criteria for declaring activities sound must be adjusted accordingly. This paper is a contribution towards better knowledge about challenges associated with implementing LPS-inspired planning processes within mechanical engineering in the offshore construction industry.

  The plans and on-going efforts of a major Scandinavian construction company to digitalise their LPS-inspired planning processes have provided the focus in this paper. A management system designed to reduce uncertainty by ensuring that soundness criterions are met, is proposed and discussed. The proposal involves predefining “process trains” and introducing tollgates and a traffic light system to visualize the soundness status. Our conclusion is that such a system is possible and desirable provided that the user threshold is low and that the system is low-maintenance. The latter is achieved by as far as possible making it an automatic part of other, already existing processes. If successful, the system could also provide additional support for decision-making in relation to principals and engineering issues.
