Weak signals and wild cards are used to scan the
environment and make systems more sensitive to emerging
changes. In this paper, the applicability of weak signals and
wild cards is experimented in a case of a highly reliable and
conservative sector, water and sanitation services. The aim is
to explore an approach suitable for water utilities. The paper
discusses different theoretical and methodological approaches
to weak signals and wild cards, and reflects these in relation to
the chosen approach. It is argued that the process of weak
signals and wild cards can serve as a communication and
reflection exercise for an organisation like a water utility.
Furthermore, incorporating weak signals and wild cards can
be an essential part in futures thinking, challenge prevailing
mental models, and make systems more open to sense and
learn from their environment. It is recommended for water
utilities to apply a loose approach on weak signals and wild
cards and embed it as a part of their organisational culture.
However, it should be remembered that the approach should
always be chosen to match the overall objectives and context.
