The average availability of the system is A = (8760-69.1)/8760 = 99.2% which is very high for most operating plants. The real issue is to quantify the cost of unreliability in monetary terms. Figure 3 shows where the accumulation of costs. From the management perspective:

Cost Of Unreliability. Cost improvement efforts are more productive when motivated from the top-down rather than bottom-up because it is a top management driven effort for improving costs. Finding the cost of unreliability (COUR) starts with a big-picture view and helps direct cost improvement programs by identifying:

In addition it became apparent that the client's reliance on Internet connectivity was not reflected in the overall systems design that was in place, and that the suggested firewall cluster would only address part of the problem. A review of the client's firewall quickly revealed the root cause of the unreliability. The firewall had been operating for over 12 months but incomprehensibly, had no updates or patches applied to the software or the operating system including patches to address VPN instability.

When DMZGlobal's Senior Security Consultants initially discussed the systems requirements with the client they were concerned by the apparent unreliability of the Check Point Firewall-1 software that they were operating.

The estimated cost for the replacement was $70,000 for the hardware and software alone. The proposed solution was viewed with some scepticism by the client and so an alternate proposal was sought from DMZGlobal.

The Cost of Unreliability. When an influential energy sector organisation ran into ongoing reliability problems with their mission-critical firewall infrastructure their incumbent support partner and vender recommended the approach of replacing their existing single firewall with a complex and expensive firewall cluster.

If the system IS sold out, then the cost of unreliability must include all appropriate business costs such as lost gross margin plus repair costs, scrap incurred, etc. If the system is NOT sold out, and make-up time is available in the financial year, then lost gross margin for the failure cannot be counted. The cost of unreliability is a management concern connected to management’s two favorite metrics: time and money.
