BIM-lean synergies in the management on MEP works in public facilities of intensive use – a case study

21st Annual Conference of the International Group for Lean Construction – IGLC 21 – Fortaleza, BrazilAEC industry has been known for budget overruns and delays for a long time. One important reason for weak performances is the difficulty to visualize the production flow, and the deficient information transmission between the different stakeholders involved in a construction project. The use of 3D models plays a significant role in facilitating the implementation of Lean principles, as it significantly improves the process visualization and supports the planning and coordination activities. This study portrays the utilization of VSM on a train station renovation project and proposes the use of a combined approach of BIM tools and Lean techniques for the coordination of MEP works.. BIM-Lean synergies were identified and set the foundation for the proposal of a team coordination approach combining BIM tools and Lean techniques. Besides an important reduction of non-added value activities and durations, the implementation of this approach achieved the alignment of interests of all stakeholders towards a common objective of meeting the overall project schedule. The findings show how a combined BIM-Lean approach improved workflow in MEP maintenance projects, and opens perspectives towards the generalization of the proposed approach into a practical Lean-BIM based production management method

Self-organization in Communicating Groups: the emergence of coordination, shared references and collective intelligence\ud

The present paper will sketch the basic ideas of the complexity paradigm, and then apply them to social systems, and in particular to groups of communicating individuals who together need to agree about how to tackle some problem or how to coordinate their actions. I will elaborate these concepts to provide an integrated foundation for a theory of self-organization, to be understood as a non-linear process of spontaneous coordination between actions. Such coordination will be shown to consist of the following components: alignment, division of labor, workflow and aggregation. I will then review some paradigmatic simulations and experiments that illustrate the alignment of references and communicative conventions between communicating agents. Finally, the paper will summarize the preliminary results of a series of experiments that I devised in order to observe the emergence of collective intelligence within a communicating group, and interpret these observations in terms of alignment, division of labor and workflow

Is the Water Sector Lagging behind Education and Health on Aid Effectiveness? Lessons from Bangladesh, Ethiopia and Uganda

A study in three countries (Bangladesh, Ethiopia and Uganda) assessed progress against the Paris Principles for Aid Effectiveness (AE) in three sectors – water, health and education – to test the assumption that the water sector is lagging behind. The findings show that it is too simplistic to say that the water sector is lagging, although this may well be the case in some countries. The study found that wider governance issues are more important for AE than having in place sector-specific mechanics such as Sector-Wide Approaches alone. National political leadership and governance are central drivers of sector AE, while national financial and procurement systems and the behaviour of actors who have not signed up to the Paris Principles – at both national and global levels – have implications for progress that cut across sectors. Sectors and sub-sectors do nonetheless have distinct features that must be considered in attempting to improve sector-level AE. In light of these findings, using political economy approaches to better understand and address governance and strengthening sector-level monitoring is recommended as part of efforts to improve AE and development results in the water sector

SOA-Driven Business-Software Alignment

The alignment of business processes and their supporting application software is a major concern during the initial software design phases. This paper proposes a design approach addressing this problem of business-software alignment. The approach takes an initial business model as a basis in deriving refined models that target a service-oriented software implementation. The approach explicitly identifies a software modeling level at which software modules are represented as services in a technology-platformindependent way. This model-driven service-oriented approach has the following properties: (i) there is a forced alignment (consistency) between business processes and supporting applications; (ii) changes in the business environment can be traced to the application and vice versa, via model relationships; (iii) the software modules modeled as services have a high degree of autonomy; (iv) migration to new technology platforms can be supported through the platform independent software model

Refinement of SDBC Business Process Models Using ISDL

Aiming at aligning business process modeling and software specification, the SDBC approach considers a multi-viewpoint modeling where static, dynamic, and data business process aspect models have to be mapped adequately to corresponding static, dynamic, and data software specification aspect models. Next to that, the approach considers also a business process modeling viewpoint which concerns real-life communication and coordination issues, such as meanings, intentions, negotiations, commitments, and obligations. Hence, in order to adequately align communication and dynamic aspect models, SDBC should use at least two modeling techniques. However, the transformation between two techniques unnecessarily complicates the modeling process. Next to that, different techniques use different modeling formalisms whose reflection sometimes causes limitations. For this reason, we explore in the current paper the value which the (modeling) language ISDL could bring to SDBC in the alignment of communication and behavioral (dynamic) business process aspect models; ISDL can usefully refine dynamic process models. Thus, it is feasible to expect that ISDL can complement the SDBC approach, allowing refinement of dynamic business process aspect models, by adding communication and coordination actions. Furthermore, SDBC could benefit from ISDL-related methods assessing whether a realized refinement conforms to the original process model. Our studies in the paper are supported by an illustrative example

Harmonisation, decentralisation and local governance: Enhancing aid effectiveness

During the last decades, international development assistance was often marked by overlaps, duplication of efforts and rivalry between multitudes of donor organisations. In order to translate the principles of the Paris Declaration into practice in the field of Local Governance and Decentralisation (LGD), different donor organisations have joined forces on headquarter level and formed a working group, the Development Partners Working Group for Local Governance and Decentralisation (DPWG-LGD), which is operating since 2006. InWEnt is hosting the secretariat of the group since 2008 and assigned Wageningen International to organise two lead donor workshops. The workshop drew a cross section of delegates who comprised development partners, consultants, academicians, members of parliament and local governance practitioners. The partner countries included Rwanda, Ghana, Tanzania and Uganda whose experiences were mutually re-enforcing and beneficial

Towards a business-IT alignment maturity model for collaborative networked organizations

Aligning business and IT in networked organizations is a complex endeavor because in such settings, business-IT alignment is driven by economic processes instead of by centralized decision-making processes. In order to facilitate managing business-IT alignment in networked organizations, we need a maturity model that allows collaborating organizations to assess the current state of alignment and take appropriate action to improve it where needed. In this paper we propose the first version of such a model, which we derive from various alignment models and theories
