The EMERGO methodology takes
ADDIE, a well-known phasing approach for instructional
materials, as its starting point. It also adopts Unified
Processing, an approach for software development. Both
approaches are transformed and extended towards the domain of
serious games (referred to as cases).
ADDIE is an abbreviation of
Analysis, Design, Development, Implementation and Evaluation
(see Figure 1).

indicate an advised order but phases can be conducted
iteratively (black arrows).
During analysis, the why, what, and for whom are
specified and it is sketched how the case will be integrated
within other instruction materials. The case idea globally
describes the case and its context of use. During design,
successive steps lead to the documents framework scenario,
ingredients scenario and detailed scenario. The
detailed scenario describes for every case character which
activities are to be carried out with which persons, which
tools and resources can be used under what circumstances. This
provides input for development where data-entry for the
flow and resources takes place, and the case is tested. During
implementation, it is specified how and for whom the
case will be available and how their case progress can be
monitored. Finally, an evaluation of whether the case
functions as intended is performed. Do users interact with the
case as expected?
Although all phases can be conducted in this order, it is
recommended to use iterations. In other words, use a Unified
Process approach with cycles instead of the classical
waterfall approach. Design assumptions and expectations can be
tested during development, and gradually a uniform picture can
arise that is supported by the whole project team. Being based
upon ADDIE and Unified Process, the EMERGO methodology
prevents overspending and minimizes risks of failures. Case
parts will be developed and tested in cycles, which results in
more intense and frequent – but not necessarily more time
consuming – communication between various stakeholders. An
important precondition for enabling shorter cycles is the
ability to carry them out quick and easy. The EMERGO toolkit
caters for this need.

toolkit are available as a separate document (accepted
