The value of DOD inventory requirements needed to support acquisition leadtime grew from about $8 billion in 1979 to about $21 billion in 1989. Recognizing that excessively long acquisition leadtime was a major contributor to the large growth in defense inventories in the 1980s, in May 1990 DOD directed the military services and DLA to take a number of initiatives to reduce acquisition leadtime as a part of a 10-point Inventory Reduction Plan. The recommended initiatives included (1) establishing procurement leadtime reduction goals, (2) shortening production leadtimes by gradually reducing the required delivery dates in contract solicitations, and (3) expanding multiyear contracting and indefinite quantity requirements contracts. Similar policy guidance for reducing acquisition leadtime, except for establishing reduction goals, was included in DOD Material Management Regulation 4140.1-R, dated January 1993. The leadtime reduction initiatives were based on a December 1986 DOD memorandum that included the recommendations of a study performed for DOD by the Logistics Management Institute. The DOD memorandum and the Institute study showed that a 25-percent reduction in leadtime was achievable by adopting methods proven successful in the private sector. In stressing the significance of the initiatives, DOD commented that each day the DOD-wide average leadtime is reduced future purchases can be reduced by $10 million. Since 1990, DOD has had only limited success in achieving the 25-percent reduction indicated by the study. As shown in table 1, DOD's average leadtime decreased by about 9 percent. On the basis of DOD's estimate that $10 million can be saved for each day the average leadtime is reduced, the 56-day leadtime reduction resulted in procurement savings of $560 million. A further leadtime reduction of 91 days will be needed to achieve the 25-percent reduction indicated by the study. Such a reduction would result in additional procurement savings of $910 million. None of the DOD components have fully implemented DOD's 1990 leadtime reduction initiatives or its 1993 policy guidance for reducing leadtime, but some have made greater efforts than others. As shown in table 1, the Navy had the greatest success and the Air Force had the least success in reducing acquisition leadtime. From 1990 to 1994, the Navy reduced the overall average acquisition leadtime by 193 days, or about 27 percent. This was accomplished by a number of actions. In accordance with DOD initiatives, the Navy first established a leadtime reduction goal of 25 percent. The Navy then had the inventory control points reduce the leadtimes shown in their databases by 25 percent for each item managed. Finally, the Navy took aggressive action over the next 4 years to shorten required delivery dates in contract solicitations and negotiations. From 1990 to 1994, the Army's average acquisition leadtime decreased by 21 days, or about 3 percent. Unlike the Navy, the Army did not establish a leadtime reduction goal, nor did it take action to obtain leadtime reductions through contract solicitations and negotiations. Instead, the Army emphasized another of DOD's initiatives to reduce leadtime by using more flexible procurement methods such as multiyear procurements and indefinite quantity type contracts. According to Army officials, quantities for follow-on years can be easily added to multiyear and indefinite quantity type contracts, which will reduce administrative leadtime to a matter of days instead of months. Also, delays in starting up production are minimized. As an example of the impact of these types of contracts, in 1993 the Army reported that a 3-year vehicle roadwheel purchase by the Tank-Automotive Command reduced acquisition leadtime by 13 months (7 months' administrative and 6 months' production) resulting in a savings of about $19 million. Similarly, by using an indefinite quantity type contract to purchase sprockets, this command reduced acquisition leadtime by 15 months and saved about $5 million. From 1990 to 1994, the Air Force's average acquisition leadtime increased by 6 days, or about 1 percent. The Air Force did not implement DOD's 1990 leadtime reduction initiatives because it felt that no action was needed to reduce leadtime based on a comparison with the leadtimes of the Navy. The Air Force delayed implementation of the initiatives pending an evaluation of the Navy's reported success in achieving a 25-percent decrease in production leadtime without degrading mission support. In its evaluation, the Air Force compared aviation data due to the similarity of parts. On the basis of this evaluation, which was completed in December 1993, the Air Force concluded that its production leadtimes for both repairable and consumable aviation parts were lower than the Navy's leadtimes, even after the 25-percent reduction. The Air Force, therefore, concluded that no action was needed to reduce production leadtime. We analyzed and compared leadtime data for the Air Force and the Navy as shown on their latest available inventory stratification reports of March 31, 1993, and September 30, 1993, respectively. We found that the Air Force's production leadtime was lower for consumable parts, but considerably higher for repairable parts. The Air Force's average production leadtime for repairable parts of 596 days was 176 days, or about 42 percent, higher than the Navy's leadtime of 420 days. Also, the Air Force's overall average acquisition leadtime of 818 days for repairable parts was 299 days, or 58 percent, higher than the Navy's acquisition leadtime of 519 days. From 1990 to 1994, DLA's average acquisition leadtime decreased by 16 days, or about 5 percent. DLA did not establish a leadtime reduction goal or attempt to reduce leadtime through contract solicitations and negotiations, as recommended by DOD's leadtime reduction initiatives. Instead, DLA concentrated on various initiatives to automate the procurement source selection process and on increased use of long-term contracting techniques, such as indefinite quantity type contracts. As the result of a study by its supply centers that identified the potential for shorter leadtimes for high dollar, high demand, long leadtime items, in February 1994 DLA drafted proposed policy guidance for implementing acquisition leadtime reduction initiatives. The proposed policy would require the supply centers to reduce leadtime by 30 percent over a 2-year period from a base of fiscal year 1992 (a reduction of 86 days). To accomplish this reduction, the supply centers would request shorter delivery times in contract solicitations, consider shorter production leadtimes as a factor in competitive bid evaluations, and periodically validate and update production leadtimes through market surveys. As of October 1994, DLA had not implemented the proposed policy, pending its decision to incorporate the policy as a part of a broader business plan it was developing. With the exception of the Navy, the military services and DLA placed no timely emphasis on the effective implementation of DOD's 1990 leadtime reduction initiatives or its 1993 leadtime reduction policy. Also, DOD was not aware of the general lack of progress made over the past 4 years in reducing leadtime because of an absence of adequate oversight information. The Navy's success in reducing leadtime by 27 percent in comparison to the limited progress made by the other DOD components shows that DOD can benefit by placing renewed emphasis on effective implementation of the leadtime reduction initiatives. One way would be to focus on the Navy's success in establishing a 25-percent reduction goal and achieving that goal by taking aggressive action to reduce production leadtime in contract solicitations and negotiations. DOD was not aware of the general lack of progress in implementing the initiatives because the annual progress reports required of the military services and DLA did not provide sufficient oversight information to make a meaningful assessment. The reports did not show historical trends in leadtime days before and after the 1990 initiatives. Also, the reports did not provide any meaningful statistics showing the extent of implementation. For example, Army and DLA reports stated that an expansion of multiyear procurements was a primary means of reducing leadtime, but the reports did not provide statistics showing the extent of the expansion. We identified additional opportunities for significant reductions in acquisition leadtime that were overlooked by the DOD initiatives. These opportunities are having inventory management activities (1) periodically validate recorded leadtime data, (2) work closely with major contractors to update old leadtime data for items with long production leadtimes (e.g., over 18 months), and (3) consider potential reductions in leadtime as a factor in deciding whether to purchase spare parts through the prime contractor or directly from the actual manufacturer. We reviewed the accuracy of acquisition leadtimes at the Air Force's Oklahoma City and San Antonio Air Logistics Centers and the Army's Aviation and Troop Command and found that the Army's leadtimes were more accurate. The Army command had a higher accuracy rate than the centers because it had recently worked closely with eight major contractors to update production leadtimes for all items with leadtimes of 18 months or longer. As a result, leadtime changes were made for 1,129 items, or 75 percent of the items reviewed. Leadtime decreases accounted for 1,061, or 94 percent of the changes. The command estimated net annual procurement savings of $88 million from using updated leadtimes to compute buy requirements. Although the Army command reduced leadtimes, our review still identified inaccuracies. We tested 26 items and found that the leadtimes for 5 items, or 19 percent, were inaccurate. For example, in July 1994 the Aviation and Troop Command used an administrative leadtime of 9 months in the requirement computation for a rotor blade tip used on the UH-60 Black Hawk helicopter (NSN 1560-01-331-3845). However, procurement history records showed that the administrative leadtime required to process the last two purchases was only 2 months. The item manager told us that the 9-month administrative leadtime was based on the time it took to award a multiyear contract and that the 2 months' administrative leadtime represented the time it took to place orders against the contract. The 2-month administrative leadtime should have been used in making purchasing decisions because it represents the actual ordering time to acquire additional parts once a multiyear contract is awarded. Command officials agreed that an adjustment should be made in the requirements system for the reduced leadtime. The two Air Force air logistics centers had a higher percentage of leadtime inaccuracies than the Army command. We reviewed the accuracy of acquisition leadtimes for 106 items and found that leadtimes for 53 items, or 50 percent, were inaccurate, resulting in overstated requirements of $7.3 million. These inaccuracies resulted from the failure to periodically validate and update leadtime data in the requirement computation database. The following examples illustrate the leadtime inaccuracies found. In November 1993, the Oklahoma City Air Logistics Center was using a production leadtime of 44 months in the requirement computation for a circuit card used on the B-2 bomber (NSN 5998-01-262-8124FW). Procurement history records showed that the 44 months was based on information provided by the contractor in July 1991. We asked center officials to contact the contractor to verify the accuracy of the leadtime. According to the officials, the contractor stated that the 44-month leadtime was outdated and quoted a current leadtime of 25 months. The 19-month reduction in production leadtime caused the value of requirements for this item to be reduced by $69,962. The circuit card is one of six B-2 bomber sample items with old and long leadtimes that the contractor updated. As a result, the Oklahoma City Air Logistics Center reduced leadtimes by an average of 14 months for five items, thus deferring future purchases. In another case, the San Antonio Air Logistics Center was using an acquisition leadtime of 100 months in the requirement computation for a signal generator used on the F-15 aircraft (NSN 6625-01-051-6832DQ). In response to our inquiries, the item manager said a keypunch error had occurred in March 1993 during file maintenance and corrected the acquisition leadtime to 38 months. Correcting the leadtime reduced the value of requirements and budget estimates for this item by $408,857. DOD promotes the purchase of spare parts from actual manufacturers rather than from prime contractors as a way to increase competition. This process is called spare parts breakout and is recognized as an effective means of achieving price reductions. Spare parts breakout has the added benefit of reducing acquisition leadtime by eliminating the processing time that a prime contractor adds for passing an order to the actual manufacturer. As part of the inventory reduction plan initiatives, the Army undertook a major program to breakout spare parts from the prime contractor for direct purchase from the actual manufacturer. Although the intent of this program was to bring about procurement economies through elimination of middleman profits, the program also contributed to a reduction in procurement leadtime. In the 1993 progress report on inventory reductions, the Army reported that the inventory commands had screened about 12,000 items for breakout in fiscal year 1992 and identified approximately 6,000 items for breakout from the prime contractor. At the Aviation and Troop Command, for example, the purchase of spare parts for the Blackhawk helicopter had been almost completely broken out. The program manager told us that in his experience production leadtime always goes down, often times by half, when a spare part is broken out for direct purchase from the actual manufacturer. Additional opportunities to buy directly from manufacturers continue to exist. For example, in response to our inquiries on six sample items managed by the Air Force's Oklahoma City Air Logistics Center, the prime contractor for the B-2 bomber advised the center that it was not the actual manufacturer for five of the six items. The contractor stated that it added 5 months' leadtime to process the Air Force's order to the actual manufacturer. Center officials agreed that the leadtime to acquire these items could be reduced simply by buying from the actual manufacturer instead of from the prime contractor and informed us that the next purchases would be made directly from the manufacturer. We recommend that the Secretary of Defense direct the Secretaries of the Army and the Air Force and the Director of DLA to place renewed emphasis on implementing the DOD leadtime reduction initiatives and to improve oversight information reported to DOD so that the progress being achieved can be measured. In doing so, we recommend that the other military services and DLA follow the Navy's lead in setting a leadtime reduction goal and achieving this goal through contract solicitations and negotiations. We also recommend that the Secretary of Defense direct the Secretaries of the Army, the Navy, and the Air Force and the Director of DLA to have their inventory management activities periodically validate recorded leadtime data to detect and correct errors, work closely with major contractors in updating old leadtime data for items with long production leadtimes (e.g., over 18 months), and consider potential leadtime reductions as a factor in evaluating the feasibility of buying directly from manufacturers instead of from prime contractors. DOD agreed that further action to reduce acquisition leadtimes is required (see app. I). However, DOD views full implementation of the policy guidance on methods of reducing leadtimes included in DOD Material Management Regulation 4140.1-R, dated January 1993, as the most effective means to accomplish this reduction. DOD stated that the military services and DLA would be reminded of the need to fully implement that guidance. In a November 23, 1994, memorandum to the military services and DLA, DOD stated that renewed emphasis on acquisition leadtime reduction was appropriate. The memorandum stated that while the greatest emphasis should be placed on full implementation of the guidance in the DOD regulation, such as gradually reducing required delivery dates in solicitations, consideration should be given to the usefulness of leadtime reduction goals and the importance of periodically validating recorded leadtime data. The memorandum also stated that full implementation of the spare parts breakout program could help reduce leadtime and that contractor furnished data could be a useful source of information in validating leadtime data. DOD asked to be advised of the actions taken to reduce leadtimes by February 15, 1995. With regard to our reference to additional savings of $910 million from further leadtime reductions leading to a DOD-wide average reduction of 25 percent, DOD commented that the Secretary of Defense issued a memorandum dated September 14, 1994, that challenges DOD components to reduce business-process cycle times by at least 50 percent by the year 2000. DOD stated further that application of this challenge to acquisition leadtime will include an estimate of possible savings. While DOD's actions are constructive, we do not believe that relying on the military services and DLA to fully implement the January 1993 policy guidance is the most effective means of achieving a 25-percent reduction in acquisition leadtime. The guidance already has been in effect for almost 2 years, and our report points out that only the Navy has been successful in reducing leadtime by 25 percent since 1990. At that time, DOD directed the military services and DLA to take a number of initiatives to reduce acquisition leadtime that are similar to those in the January 1993 guidance. Also, the guidance does not contain a leadtime reduction goal. Furthermore, we believe that improved oversight is needed if leadtime reductions are to be achieved. DOD's comments do not address this part of our recommendation and the January 1993 guidance does not require the military services and DLA to provide DOD with oversight information on their progress in reducing leadtimes. Also, DOD no longer requires annual reports from the military services and DLA showing their progress in implementing the 1990 inventory reduction plan. Alternative means are available for providing DOD with oversight information. One way would be to require that the military services and DLA include leadtime data in their annual Defense Business Operations Fund budget submissions to DOD. These submissions could show the progress being made in achieving a 25-percent reduction in acquisition leadtime, using fiscal year 1990 as the base year for measuring progress. To evaluate the effectiveness of DOD's leadtime reduction initiatives, we held discussions and collected information at headquarters of DOD, Army, Navy, Air Force, and DLA, Washington, D.C.; the Oklahoma City Air Logistics Center, Tinker Air Force Base, Oklahoma; the San Antonio Air Logistics Center, Kelly Air Force Base, Texas; and the Army Aviation and Troop Command, St. Louis, Missouri. We reviewed DOD guidance and initiatives for managing acquisition leadtimes and the implementing policies, procedures, and practices of the military services and DLA. To determine if additional leadtime reduction opportunities exist, we obtained computer tapes from the Air Force and the Army that identified acquisition leadtimes for all spare parts managed by the two Air Force air logistics centers and the Army command as of March 31, 1993. From data extracted from the tapes, we selected 106 Air Force items and 26 Army items for review. These items represented a mix of items either planned to be bought in fiscal year 1995 or having long leadtimes of more than 50 months. We compared leadtime estimates used in requirement computations to leadtimes actually experienced and other leadtime information in item manager files. We selected Air Force and Army locations for detailed review because of their large acquisition leadtime requirements. We used the same computer programs, reports, records, and statistics DOD, the military services, and DLA use to manage inventories, make decisions, and determine requirements. We did not independently determine the reliability of all of these sources. However, as stated above, we did assess the accuracy of the leadtime information by comparing data contained in the requirements system with data contained in item manager files. We performed our review between October 1993 and August 1994 in accordance with generally accepted government auditing standards. As you know, the head of a federal agency is required by 31 U.S.C. 720 to submit a written statement on actions taken on our recommendations to the House Committee on Government Operations and the Senate Committee on Governmental Affairs not later than 60 days after the date of this report.

Summary:
GAO reviewed the Department of Defense's (DOD) efforts to reduce acquisition leadtimes. GAO found that: (1) DOD has made only limited progress in reducing its acquisition leadtimes because the military services and the Defense Logistics Agency (DLA) have unevenly implemented the leadtime reduction initiatives; (2) no DOD agency has fully implemented the 1990 initiatives or the 1993 policy guidance for reducing leadtimes; (3) the Navy has been the most successful and the Air Force the least successful in reducing acquisition leadtimes; (4) additional leadtime reductions can be achieved by prompt implementation of DOD initiatives, periodic validation and updating of leadtime data, and purchasing spare parts directly from the original manufacturer; and (5) DOD could reduce costs by $1 billion over a 4-year period by reducing acquisition leadtimes.
