By prioritizing the end-effector, its failure had only a minor impact on the design.

During each iteration of the development cycle, the selected feature is implemented according to the variable-detail approach.
However, the ability to assess the influence of the variable-detail approach is limited by the absence of tooling for model orginization and testing.
However, the ability to assess the influence of the variable-detail approach is limited by the absence of tooling for model organization and testing.
Without the tooling it is difficult to switch between model versions, undo design changes or run automated testing.
Furthermore, as the development did not distinct between design and model, the models used often contained more detail than strictly necessary.
Both these limitations resulted in models that would surpase the minimal required level of detail; therefore, it is not possible to assess whether the minimum required level of detail can be established with passing all the tests.
Nevertheless, the variable-detail approach introduces a step wise addition of detail that enforces a structered method similar to the development cycle.

Nevertheless, the variable-detail approach introduces a step wise addition of detail that enforces a structured method similar to the development cycle.

It is unfortunate that the development cycle did not include a structured method to define the features nor their order of implementation.
The performance of the variable-detail approach is currently hindered by the absence of tooling.

These features stem from spliting the functionality and each of the feature is then developed using the \ac{ridm}.

\section{Recommendations}
%Bovenop de hierboven genoemde required adaptations, zijn er ook nog een aantal andere aanbevelingen.
%Dit bevat een deel visie vanuit de design method, maar ook mogelijkheden om het design verder op te pakken.
% Voordat er de hierboven genoemde adaptations worden meegenomen in het RIDM, is er eerst aanvullend onderzoek nodig naar de exacte invulling.
% De aanbevelingen voor dat aanvullende onderzoek zijn als volgt:
Before any of the adaptations are applied to the \ac{ridm}, further research on the exact format of these adaptations is recommended.
The recommended steps taken in further research are:

\begin{itemize}
% - Bepaal in wat voor setting het RIDM moet opereren: Denk aan: cps-soort, samenstelling van ontwikkelteam, focus van de design methode.
% Aan de hand van deze setting.
\item \emph{Make the application area and purpose of the \ac{ridm} specific}: To design a good design method, the design process must start with a clear problem description.
Currently, the \ac{ridm} does provide a design method, but does not state clear requirements such as:
\begin{itemize}
\item \emph{Type of \ac{cps}}: mainly hardware, software or control?
\item \emph{Design focus}: improve reliability, real-time guarantee, reduce complexity, shorten development-time?
\item \emph{Internal or external use}: is the client directly involved?
\item \emph{Development team}: number of developers from what background?
\end{itemize}

Above all, it prevents the \ac{ridm} of becoming a "master of none".
\item \emph{Explore existing design projects that share the application area and purpose}: To avoid a reinvention of the wheel or solve a problem that does not exist, it is recommended to collect and evaluate the results of existing design projects with at least the following questions:
\begin{itemize}
\item What type of design paradigm or model is being applied?
\item Where is the complexity in the project and how is it dealt with?
\item How are the metrics of \emph{cost of change} and \emph{chance of failure} defined?
\item How are the design and models connected?
\item Which design tools are used by the design team? Why are they used?
\item Are there common problems that hinder (almost) all design projects?
\item How is the client involved in the development process?
\item What considerations are made to chose between modelling or hardware prototyping?

Depending on what the results and conclusions of the recommended research topics are, a strategy has to be created to further develop the \ac{ridm}.
Currently, there are two likely scenarios:
\begin{itemize}
\item Make the \ac{ridm} part of an existing design model, such that the advantages are integrated with existing design models.
\item Develop the \ac{ridm} into a complete design method, such that it can be used for the development of the complete product life-cycle.
\end{itemize}
Independent of what strategy is chosen, it is recommended to:
\begin{itemize}
\item Implement the adaptations as described in this thesis.
\item Perform the adaptations and improvements of the \ac{ridm} with a multi-disciplinary design team.
\item Evaluate the \ac{ridm} with projects that are within the application area of the \ac{ridm}.
\end{itemize}

The recommendations result in a more focussed development of the \ac{ridm}.
But expected is that a full development of the \ac{ridm} takes multiple years and multiple developers to complete.
However, it is possible to improve separate techniques from the \ac{ridm}.
These techniques can improve existing design methods.
Based on this thesis, the following research topics are recommended:

\begin{itemize}
\item \emph{A technique or protocol for to organize the parameters of a design, such that the parameters can be used in modelling}: Can the current modelling tools be adapted to read parameters from a database and can design tools be adapted to write parameters to a database?
\item \emph{Tooling for modelling software, to allow for unit testing}: Software development applies unit testing, where behavior of each function is tested separately.
In modelling this would allow every sub-model to be tested separately.
\end{itemize}
