\section{The Product: Building WDC}

Figure~\ref{fig:WDCphoto} shows the new IST building, which is the product of a significant
architecting effort.

\FigureTextwidth{WDCphoto}{The product}

Architecting a product involves 3 major phases, see also figure~\ref{fig:WDCwhatIsArchitecting}:
\begin{myList}
\item Understanding {\bf why}
\item Defining {\bf what}
\item Guiding {\bf how}
\end{myList}
The {\bf why} and the {\bf what} of a product are directly derived from the needs and the constraints
of the stakeholders. The {\bf what} is consolidated in a requirement specification. To
determine the{\bf what} sufficient understanding of the {\bf how} is needed to ensure
the feasibility. Understanding the {\bf how} requires a significant amount of technology and
construction know-how.

The authentic objectives of the Philips management with respect to the Campus
can be read (in dutch) in figure~\ref{fig:WDCdrivers}. These objectives and subgoals
are translated in English, see tables~\ref{tab:WDCdrivers}~and~\ref{tab:WDCderivedDrivers}.

\myTable{WDCdrivers}{Objectives of the Philips management w.r.t. the Campus}
\myTable{WDCderivedDrivers}{Subgoals w.r.t. the Campus}

The objectives make it clear that the Philips management is aware of influence of the housing
on the organization and may other human factors. The objectives address mostly human
factors, within an economic efficiency constraint.

\FigureImposeWidth{WDCplattegrondParterreLeeg}{The architects vision}{10cm}

The vision of the architects, see figure~\ref{fig:WDCplattegrondParterreLeeg} is to create
a very {\it open} and {\it transparant} building.
{\it Open} and {\it transparant} stimulates {\it communication}, {\it sharing} and
{\it cooperation}. An modern outlook and embedding the building in the high-tech~campus
creates a stimulating and innovative environment.
 
\myTable{WDCwishesInhabitants}{Wishes and concerns of the inhabitants}

Somewhat late in the process the final inhabitants were involved in the internal
design of the building. Table~\ref{tab:WDCwishesInhabitants} show some of the wishes of
the inhabitants. especially the {\it concentration} requirement was undervalued by
the architects and some raging debates took place about this subject.

Figure~\ref{fig:WDCfloorWithRooms} shows the internal design after taking into account the
{\it concentration} requirement. The open space is mostly filled with (small) two person
rooms, to provide the required quiet atmosphere. The informal communication is
now foreseen near the two coffee pantries.

The openess is reduced to open staircases and the atrium at the south side of the building.
Figure~\ref{fig:WDCtrappenhuis} shows an impression of the space near the staircase.

The work of the architect is to bridge the stakeholder world and the construction world.
This construction world is much more technical, many technical aspects must be taken into
account by the architect. 

\FigureImposeWidth{WDCarchitectingTechnical}{The technical side of the architecture}{8cm}

Figure~\ref{fig:WDCarchitectingTechnical} shows a number
of the more technical aspects:
\begin{myList}
\item Facilities
\item Infrastructure
\item Design aspects
\item Construction aspects
\end{myList}

Note that most technical aspects have a counterpart in terms of stakeholder concerns.
For instance safety is a major concern of a plant manager, which results in many procedures,
guidelines, provisions and hence also in requirements for the new building.

\FigureTextwidth{WDCannotatedCAFCR}{WDC architecting mapped on ''CAFCR''}

In technical architecting we promote the ''CAFCR''-model\cite{www:COPAtutorialSPLC1}.
This model provides a spectrum of 5 viewpoints, ranging from the customer objectives
(customer {\bf what}) to the realization (product {\bf how}).
Figure~\ref{fig:WDCannotatedCAFCR} shows the architecting aspects mapped on this model.
