w6Attitude and technology

These are the most effective catalysts for change

Pat Gehl, JB Systems, Woodland Hills, California

JB systems2 copyBefore the 1970s there was little if any attention given to maintenance practices other than that found in Nuclear Navy. The Navy, particularly the submarine fleet, installed and practiced rigid preventive maintenance procedures for obvious reasons. Industry, on the other hand, took the position that most preventive maintenance did not result in enough savings or product improvement to warrant the cost.

Chapter I: The awakening
During the 70s and 80s, two events forever changed this closed minded attitude and approach of management towards maintenance practices. First was the arrival of Japanese automobiles that were priced affordably and made to quality standards. Meanwhile, the Big Three ignored quality and produced inferior products. As a result of inefficient manufacturing practices and overstaffed plants, Detroit was forced to price domestic cars much higher than those of the Japanese. The outcome was devastating to the domestic automobile industry and became one of the initial catalysts for change--that of an attitude towards product quality as it relates to maintenance of plant and equipment.

Early in 1983 a second catalyst for change came in the form of technology--the microcomputer with a hard disk. With the availability of a relatively low-cost computer, several entrepreneurial companies began developing maintenance management software for these PCs. This catalyst had a significant impact. For the first time the maintenance staff had a tool at their disposal that enabled them to quantify the cost and effect of poor maintenance practices.

In order to validate this theory, I put the question to the users of current maintenance management technology.

It became commonplace to hear of companies using this hardware and software combination to reduce the cost work performed by outside contractor by as much as 80 percent, reduce maintenance inventory cost by as much as 30 to 40 percent, and reduce the downtime on critical equipment by as much as 20 to 30 percent. What made these improvements possible was producing and tracking preventive maintenance procedures using the maintenance software. Thus began the technical catalyst for the shift in maintenance practices and attitudes towards their value.

Chapter II: The growing
The simple work order module of the early software and standalone PC soon evolved to include materials and purchasing modules now operating on large networked systems. Some of the Novell networks, for example, accommodated upwards of 100 terminals. The 5 megabyte hard drive was replaced by drives capable of storing thousands of equipment items, tens of thousands of spare parts, and a year's worth of work orders and purchase orders.

The technology catalyst was now in full swing. The maintenance software now connected to software for predictive maintenance; CAD; bar code; and had shop floor and dispatch capabilities. The systems grew in size and began to produce genuine operational data that management at every level could use. The availability of reliable operational information enabled maintenance management to measure the results of maintenance practices and apply appropriate changes where needed. This distilled information began to find its way into the company's management reports and was used to improve manufacturing scheduling, spare parts purchasing, product pricing, and materials handling practices.

The maintenance department was beginning to establish processes that focused on managing maintenance as a business unit. One of the more sophisticated examples of this new movement was the collaboration between the maintenance and marketing departments for pricing multiple products produced from the same production line. For example, if a line can produce both ice cream and yogurt, then the question of whether one product costs substantially more in terms of maintenance could be answered. If one product does, in fact, cost substantially more, then it could have a significant impact on product pricing. Again, both the attitude of management and the availability of state-of-the-art technology served as the catalyst for change.

Additional examples of using information from maintenance packages abound. Just think in terms of retaining OSHA and EPA type work orders to establish compliance, retaining work orders with printed lockout/tagout procedures to demonstrate adherence to safety regulations, and retaining general preventive work orders to support ISO 9000 certification. Reports showing the cost of repair work for equipment under warranty justify backcharging the manufacturer. Thus the information age reached the maintenance department and the department responded positively. Although the use of current technology and management's attitude towards maintenance practices provided beneficial results for everyone, but the best was yet to come.

Chapter III: The maturing
The 90s saw the introduction of another major change in both management attitudes and current technology that propelled the maintenance Department into becoming a major part of the enterprise-wide system. The technology catalyst came courtesy of Mr. Gates and Mr. Grove while the shift in attitude came largely from accepting Deming's teachings of the 80s.

Gates brought Windows, Grove brought powerful PCs, and Deming brought the concept of self-empowerment as stated in his 8th point--"No one can put on his best performance unless that person feels secure."

The technology shift in software and hardware resulted in Windows-based, client/server configurations such as that shown in Figure 1. The significance of this capability is two-fold. First, it became straightforward to include the maintenance software as part of the enterprise-wide system. Second, it placed PCs throughout the plant floor that were readily accessible by both the crafts and the operators. This capability enabled management embracing the Deming doctrine or a derivation thereof to empower craft employees to schedule their own work, operators to enter work requests, and those responsible for spare materials to manage inventory levels and reordering practices using a PC displayed work queue. A typical craft work queue is shown in Figure 2.

These work queues display the status of every work order in the plant. A checkmark indicates the task is currently assigned to an employee while those without a checkmark are available for the taking. The queues can be sorted by any combination of priority, craft, and work area. Major organizations using such work queues for employee empowerment--Gillette, General Motors, United Biscuits, Solar Turbines, and MD Anderson--each realize significant benefits.

The results of this management attitude change manifest themselves as improved preventive practices, reduced inventory levels and losses, reduction in staff levels, and the drastic reduction of critical equipment failure. When fully practiced, employee empowerment repeatedly demonstrates that employees do want to help to make their companies become successful and competitive.

What made these improvements possible was producing and tracking preventive maintenance procedures using the maintenance software.

C. Paul Oberg of the Copley Consulting Group, Inc. commented on the current management attitude change in his p JB systems2 copy aper, "Self-Directed Empowerment." There he wrote that employee empowerment presents companies with an opportunity to
manage indirect cost while minimizing the cost of managing.
He noted that the self-directed work force will:
  • focus on deferred, demand, and preventive maintenance activites;
  • be thorough in the analyzing and planning of work;
  • assume responsibility for identifying maintenance work;
  • be accountable for the proper repair and maintenance of assigned equipment; and
  • conduct their duties in an efficient and professional fashion.
These points indicate that the changes in technology and management's attitude have, in turn, manifested themselves into another catalyst for change--that of the employee attitude. In order to validate this theory, I put the question to the users of current maintenance management technology. The intent was to ascertain the extent that the empowerment change had grown and what results, if any, they observed. In the faxback questionnaire, 95 percent indicated that employee empowerment was being practiced in their companies and felt the practice was increasing throughout the U.S. When asked about the results of this attitude shift:
  • 15 percent felt employee empowerment resulted in the employees

  • having a better understanding of their company's business procedures and goals.
  • 40 percent felt employee empowerment resulted in employees becoming more responsible and becoming happier with their jobs.
  • 10 percent felt employee empowerment was not a good idea.
  • 5 percent felt employee empowerment resulted in a

  • shift in many responsibilities from maintenance
    to production.
  • 5 percent felt employee empowerment resulted in employees getting better tools for their trade.
  • 5 percent were not sure of the results.
Epilog
It appears that technology advances in terms of PCs and asset management software combined with the nation's demand for improvement in product quality and productivity have indeed provided a catalyst for change in maintenance practices. The changes resulted in a restoration of worker attitudes towards taking ownership and pride of their jobs. On the production side, this means higher quality products while on the maintenance side it results in better production environments.

The maintenance employees seem to be affected the most by these changes. As a class, they feel better about themselves and their work. They accept the responsibility to keep facilities and equipment in its best possible operating condition and they do it without mandate.

Results of embracing the change towards employee empowerment is typified by the experiences of Gillette Facilities Manager, John Miller and his maintenance staff who have been practicing employee empowerment since 1992. John reports that his results include:

  • Development of an equipment purchasing procedure that requires those responsible for using and servicing the equipment to sign off on a checklist.
  • Development of an ongoing training curriculum for mechanics.
  • The elimination of recalls when unfinished repair work extends from one shift to another.
  • Significant improvement in the cleanliness of the restrooms.
  • Corrective action teams now determine whether machine downtime was excessive and set standards.
  • The development of clear and concise safety guidelines and procedures.
"It's the employee doing a job who is the expert in that job." John adds, "and the employee is the one most able to make recommendations about how to improve processes and procedures."

It has been stated that change is the only constant. It's nice to have this recent attiude and technology shift be the catalyst for a constant change for improvement.
