Introduction to Myself Lecturer in Construction Management since 2005 Interested in Design and Knowledge Management PhD in Civil Engineering Undergraduate studies in Structural Engineering Disability: Poor eyesight
Outline First Principles “Design”? “Management”? “Design Management”? Why design management is difficult but important Tools we can use
First Principles: Design 1/2 “ The conception and planning of the artificial” (Buchanan 2000) “ The process of developing information about an object that has not previously existed.” (Ullman 1994) “ The most essential design activity is the production of a final description of the artefact.” (Cross 1989) (a description that would enable someone to build the artefact)
First Principles: Design 2/2 Yes, but  how  are designs generated? Rational (or rationalisable)  process  made up of distinct phases ? Rational problem solving? Subjective, deeply human experience? Social, collaborative activity? Design  ≠  construction
First Principles: Management 1/2 Oxford English Dictionary: “Organization, supervision, or direction; the application of skill or care in the manipulation, use, treatment, or control (of a thing or person), or in the conduct of something.”  Gray and Hughes (2001): To conduct things and people in order to achieve some end.” Managing  ≠  doing
First Principles: Management 2/2 Dictionary definition uses the word “ organisation”  –  from the notion of organs in the human body. To organise something is to arrange the elements into a coordinated whole. When it is difficult to deal with a whole, it is useful to split the whole into pieces, and deal with each piece in a separate but coordinated way. Disassembly must not destroy essence – reductionism  vs. holism.

First Principles: Design Management 2/5 A long time ago… Architect/ Masterbuilder Workmen or labourers CONSTRUCTION Architect/ Masterbuilder Architect/ Masterbuilder DESIGN MANAGING DOING
First Principles: Design Management 3/5 Recently… Const./Proj. Manager or General Contractor Subcontractors CONSTRUCTION Architect/ Engineer Architect/ Engineer DESIGN MANAGING DOING
First Principles: Design Management 4/5 The future… Const./Proj. Manager or General Contractor Subcontractors CONSTRUCTION The Design Manager Architect/ Engineer + Others DESIGN MANAGING DOING
First Principles: Design Management 5/5 “ A management framework for timely delivery of good, accurate and build-able designs that meet the stakeholder requirements.” – Design Management Handbook by Lee Bibby “ The management of people and resources in a multidisciplinary process, performed in a series of iterative steps, to conceive, describe and justify increasingly detailed solutions and costings to meet the needs of the stakeholders.” – Professor Simon Austin Module notes, CVP010 Design Process Management. Orchestra metaphor
Changes in the Const. Industry One person/entity oversee the entire design and construction process    Co-ordination of multiple specialist designers and works contractors. Specialisation, fragmentation.  As work becomes more complex, so more skills are needed to accomplish it. Architect as project leader    Ambiguity:  Who’s the boss? Erosion of the role of architect. Complex financing, accounting before an architect is even hired. Leadership of project changes as project progresses (For more, see Table 1, Page 2 in Gray and Hughes 2001)
Who Contributes to the Design? CONTRIBUTION STAGE Brief Detail Concept and Scheme Specialist Engineering Design Construction Client Architect Engineer Specialist Gray and Hughes 2001. Fig 9
Construction Man.  ↔  Design Man. Construction: Complicated Collaboration between many specialists Const. Man./General contractor relieves architects and engineers of the need to manage construction Design Complicated,  many specialists    Design management to relieve entire team of management role
Characteristics of Design 1/2 Many stakeholders, disciplines Different disciplines because complexity    differentiation Different organisations because of transaction cost economics Each discipline has its own language and way of working We want this, but we need to provide integration and coordination
Characteristics of Design 2/2 Design is problem seeking (or problem definition) as well as problem solving Design is iterative.  No right answer first time.  No perfectly right answer at all? “Designer” is often not “builder”.   Contrast between design and construction.
