FIGURE 5. For a given set of symptoms, several diagnostic tools are conceivable. However, the end use
alone can direct the development of the tool
ment of a diagnostic tool.
However, it is the eventual use of
the tool that will determine its design.
The expected use could be a
simple one-off answer to support triage
(Case 1 in Figures 3 and 5), in
which case a diagnostic based on
temperature (for instance, using a
thermometer) might be sufficient.
In a more extreme case, if a new
pathogen is suspected, DNA sequencing
could be envisaged to
determine the cause of the sickness
(Case 3). In this instance, the diagnostic
tool can be used to both gain
insight and make decisions.
An intermediate case is that of fast
preliminary assessments, for which a
new type of field microscope might
be sufficient (Case 2). The medical
analogy presented here provides
a simple illustration of tool differentiation
(in this case, model development)
based on final usage to ensure
appropriate design.
All modeling tools are unique and
their usages vary from one project to
the next. Nonetheless, only with effective,
targeted communication between
the user and the modeler can
value be delivered. Aspirationally,
with modern software, modeling will
become a more accessible activity
so there will not be a distinction between
modelers and problem owners
- rather, all users will be able
to do some model development. In
the meantime, you must think carefully
about how to foster the most
effective communication among all
parties the next time you integrate
modeling into your workflow.

Authors
Christophe Grosjean is the technology
and innovation lead for
formulation
engineering at
Syngenta AG (Breitenloh 5, 4333
Münchwilen, Switzerland. Phone:
+41 62 868 5686; Email:
christophe.grosjean@syngenta.
com). He holds a chemical engineering
degree from IUT Le Montet
(Nancy, France), and a Ph.D. in
physical organic chemistry from Durham University.
After further postdoctoral studies at Durham, he joined
LyraChem Ltd, a start-up company established from a
collaboration between Newcastle and Durham universities'
chemical engineering and chemistry departments,
respectively. During that time, he was responsible for
the process modeing, experimental studies, and reporting
of business projects. Grosjean joined Syngenta in
2013, and has worked on a number of process modeling
projects, supporting the seeds and active ingredients
parts of the business.
Anita Rea is
process
studies
manager at Syngenta's International
Research Center (Bracknell,
Berkshire RG42 6EY, U.K. Phone:
+44 1344 41 4102; Email: anita.
rea@syngenta.com). She holds a
Ph.D. in Biophysics from the University
of Notthingham, and was a
postdoctoral researcher at the
MRC Laboratory of Molecular Biology
(LMB) in Cambridge, U.K. In her current role, Rea
leads a cross-disciplinary department of engineers,
chemists and physical scientists in the application of
fundamental science to the development, manufacture
and formulation of agrochemical active ingredients.
Patrick M. Piccione is the head
of formulation and process sciences
at F. Hoffmann-La Roche
(Grenzacherstrasse
124,
4070
Basel, Switzerland. Phone: +41
61 687 7510; Email: patrick.
piccione@roche.com). He spent
seven years in materials development
at Arkema, followed by nine
years at Syngenta, leading process
engineering science. At Syngenta, Piccione also
led a division-wide mathematics and data-science
strategy, which prominently featured models together
with their development and dissemination. He holds
B.S. degrees in chemistry and chemical engineering
from MIT, as well as an M.S. in chemical engineering
practice, and a Ph.D. in chemical engineering from the
California Institute of Technology. He has co-authored
more than 30 journal and proceedings articles on various
topics. He is a Chartered Engineer and Fellow of the
IChemE, and is currently serving on the Executive Board
of the European Federation of Chemical Engineering.
