Advantages, Limitations and MBO vs MBE

Advantages of MBE:

• Saves managerial time — routine matters within the tolerance range are handled without escalation, freeing senior management's time for genuinely important issues.
• Focuses attention on critical problems — because only significant deviations reach the manager, their analytical effort is concentrated exactly where it is most needed.
• Encourages delegation — since routine decisions are left to lower levels, MBE naturally promotes delegation of authority and builds the decision-making capability of subordinates.
• Faster corrective action on genuine problems — because exceptions are flagged promptly rather than getting buried in a flood of routine reports, corrective action on real problems tends to be quicker.

Limitations of MBE:

• Depends heavily on the reporting system — if the underlying information/reporting system is poor or delayed, genuine exceptions may not be identified in time, defeating the whole purpose of the technique.
• Setting the right tolerance range is difficult — a tolerance band set too narrow floods management with reports on trivial variations (defeating the purpose); one set too wide may let a genuinely serious problem go unnoticed for too long.
• May overlook favourable exceptions with hidden causes — a result significantly BETTER than expected is also an "exception" under MBE and deserves investigation (it might reveal an unsustainable shortcut, or a genuinely better method worth replicating), but in practice attention often goes only to unfavourable deviations.
• Not suitable for every kind of decision — some matters (e.g. anything involving legal compliance, safety, or reputational risk) need to be reported regardless of whether they fall inside or outside a normal statistical tolerance range.
