There is no one-size-fits-all approach to strategic IM management. Each organization must balance risks with business need to determine the most appropriate approach.
Banning IM may not be right for all organizations. A ban may lead to rogue use, employee outcry, or client complaints.
Standardization reduces risks, but limits communication to internal chat.
If you opt for flexibility, be sure to select a gateway/IM management technology product that enables you to control risks and manage use within policy and regulatory guidelines.
Weigh both sides of the productivity issue before banning IM outright.
Don’t assume every employee needs or is entitled to IM access.
