Inertia pulls businesses along even when they try to change direction and can create the illusion of activity instead of real change. Inertia is fostered by an unwillingness to question current practices and serves to justify inaction. Main causes of inertia include outdated training, unchallenged employee beliefs, inflexible systems and aging leadership perspectives. To overcome inertia, leaders should annually challenge models with staff, communicate new directions, invest in supporting the vision, and invest in personal and team development through training outside their comfort zones.
