10.7 Recommendations to implement a collaborative decision-making process

Based on the literature, the following are recommendations to implement a collaborative decision-making process:

Involve the right stakeholders, who are impacted by the decision and who have relevant technical knowledge on the impacts of the decision. Collaborative decision-making works when the right stakeholders are involved at the right time (Ballard, 2000b; Suhr, 1999);

Defer decisions until the last responsible moment as described in SBD method (Ward et al., 1995);

Make decisions from the perspective of long-term benefits and needs;

Make decisions slowly by consensus and then implement them quickly; this concept is known as Nemawashi (Liker and Meier, 2006);

Separate value from cost, and allow money to move across contractual and system boundaries. One of the most common mistakes in decision-making is to consider cost as a regular factor (Schöttle and Arroyo, 2016; Schöttle, Arroyo, and Haas Georgiev, 2017; Suhr, 1999);

Be transparent. No method ensures the right decision, but an honest and transparent decision-making process is more likely to recommend a beneficial decision (Suhr, 1999);

Give weight to advantages rather than factors or attributes (Suhr, 1999).
