PROJECT MANAGEMENT WITHIN THE ARMY MATERIEL
COMMAND.

F. S. Besson, Jr. (U.S. Army, Materiel Command, Washington,
D.C.)

(National Advanced-Technology Management Conference, Proceedings, Seattle, Wash., Sept. 4-7, 1962.)

IN: Science, Technology, and Management. New York, McGrawHill Book Co., Inc., 1963, p. 90-105.

Discussion of the recent reorganization of the Army as a result of which the Army Materiel Command is established to integrate the materiel functions of the Army. A strong emphasis is placed upon the use of vertical project management, and it is shown how this concept is being utilized in the AMC. It is suggested that the discussion of the functions. roles, and organizational relationships in this new type of organization should be meaningful in advanced technology industries. The conflict between functional and project management is outlined and ways for ameliorating it are suggested. The idea of the "red line" a subordinate communicating directly

with the top level in the organization while bypassing intermediate superiors is presented, and it is indicated that it is a departure from the traditional military concept of single chain of command.

Analysis of the problems of government-industry program management based on such projects as the Redstone, the Jupiter IRBM, the Explorer and Juno series, the Pershing missile, and the Saturn space vehicle. The uncertainty in decision making and the conflicts existing during the late 1940's and early 1950's regarding the national rocket and missile program are pointed out. The importance of clearly defining the problems and objectives of a program is stressed, indicating that this is one of the most important managerial functions in establishing a new program on the right basis. However, the conflict of values which often permeates a program is spotlighted precisely and clearly. It is indicated that the built-in conflicts among the customer, the national financial authority, the final user of the product, the scientists and designers, the production-oriented people, and business managers are to be expected in advanced-technology programs. The establishment of dual approaches in meeting new scientific and technical problems is proposed. Finally, valuable suggestions for handling some of the specific problems involved in actually managing a program are provided. The vital importance of maintaining active communication and coordination between the various groups within the project is stressed, and the role of project management in this activity is outlined.

THE DEFENSE INDUSTRY MANAGEMENT CHALLENGE OF
THE SEVENTIES.

John J. Bennett (USAF, Systems Command, Andrews AFB,
Washington, D. C.).

1966, Paper 66-WA/MGT-16. 7 P. 7 refs.
Members, $0.75; nonmembers, $1.50.

The paper addresses the alleged incompatibility between the current government procurement practices and the trend toward tighter management control techniques in dealing with defense and space contractors. It attempts to show that the fundamental problem s not incompatibility between greater contractor risk and control, but how government has applied the new control techniques. It describes several actions the government is undertaking to carry out future development and implementation of management control procedures in a more orderly manner and in a way that will reduce the impact on industry. it concludes that considerable opportunity exists for industry to improve its participation in a partnership with government that will benefit both parties.

TOTAL VALUE CONCEPTS IN THE CONTRACT DEFINITION
PHASE.

S. Robinson (Radio Corporation of America, Defense Electronic
Products, Missile and Surface Radar Div., Moorestown, N. J. ).
IEEE Transactions on Aerospace and Electronic Systems, vol.
AES-2, July 1966, p. 402-408. 5 refs.

For large military research and development projects, Contract Definition type contracts are meeting the cost-effectiveness challenge by an intensive study of the total value considerations in a project

before it starts. This has extended the application of total value concepts throughout all project activities and broadened their scope. Total value concepts are discussed and applied to various aspects of system effectiveness. The effects of configuration, reliability, and system availability upon overall costs are considered, and cost vs performance optimization curves are shown. Practical measures of service life are calculated. Break-even curves relating acquisition and operational costs are shown. A decision matrix method for assessing system value is included. A case study graphically showing the effects of value considerations on a typical radar antenna tower is contained in the paper. (Author)

IN: NATIONAL SYMPOSIUM ON RELIABILITY AND QUALITY CONTROL, 11TH, MIAMI BEACH, FLA., JANUARY 12-14, 1965, PROCEEDINGS. [A65-18710 09-15]

Symposium sponsored by the Institute of Electrical and Electronics Engineers, American Society for Quality Control, American Society of Mechanical Engineers, Institute of Environmental Sciences, and Society for Nondestructive Testing. New York, Institute of Electrical and Electronics Engineers, 1965, p. 115-124.

Presentation of a procedure for determining the final fee in Cost-Plus-Incentive-Fee (CPIF) contracts. As a basic part of the plan, it is assumed that the contractor is willing to take a risk of having essentially all of its fee eliminated when contract performance is poor, and, in return, be awarded a substantial increase in fee over the negotiated target when contract performance is superior. It is noted that the Armed Services Procurement Regulations (ASPR) limit the final fee to a maximum of 15%. It is shown that between these two limits, the contract performance is determined by four incentive factors: cost incentive, schedule incentive (delivery of hardware and documents), product performance incentive, and reliability incentive. In conclusion, four advantages of CPIF contracts are presented: (1) the contractor will have the added incentive to secure the highest caliber management; (2) the cost of the contractor's operations to fulfill the contract will generally go down; (3) the customer and the contractor share the risks, since the contractor could lose a large portion of his target fee for inferior results; and (4) the reliability requirements become meaningful because they can influence the final fee determination.

Discussion of the concept of program management in today's aerospace business in relation to the requirement for an effective management to cope with a complex management task involving multiple interfaces of business and technical disciplines. Some organizational precepts are presented as being fundamental to achieving an effective management system in a multi-program company environment of major aerospace programs. The program management system evolved for the development of the DC-9 Jet Transport is described to illustrate the implementation of the concept. In this program, each program manager has under his direct control the function of contract administration, subcontract administration, work authorization, budget authorization, cost control, and the measurement and control of program progress.

Discussion of problems, techniques, trends, and possibilities of incentive contracting, with application to specific aerospace projects. It is stated that it is difficult to draw conclusions about a new and, in a sense, exploding development such as the one treated. The work undertaken to date by the DOD, NASA, and segments of industry promises future benefits. More and more sizable incentive contracts, with greater profit/loss possibilities, are certain. And the planning and execution of these contracts will demand a growing percentage of management's attention. It is noted that lack of sufficient management attention to incentives will preclude successful incentive contracting and thwart the benefits potentially obtainable.

VALUE ENGINEERING IN PROGRAM CONTRACTS.

S. Robinson (Radio Corporation of America, Missile and Surface Radar Div., Moorestown, N. J.).

Journal of Value Engineering, vol. 2, May 15, 1964, p. 61-66. Discussion of the Project Definition Phase (PDP) method of contracting, considered in a sense as an intensive value study conducted by all project activities. A significant aspect of PDP is the concept of system trade-offs among cost, performance, and schedales. A realistic and practical approach is to maximize capability for a specified cost or to minimize cost for a specified capability. The establishment of the PDP system is considered to have put value engineering into official government contracting policy. ious aspects of the problems involved are treated in detail.

ANCILLARY BENEFITS OF AN AUTOMATED R&D RESOURCES
ALLOCATION SYSTEM.

Ambrose B. Nutt (USAF, Systems Command, Research and Technology Div., Flight Dynamics Laboratory, Wright-Patterson AFB, Ohio).

Members, $0.75; nonmembers, $1.50.

The ancillary benefits derived from use of an automated R and D resources allocation system are described, prefaced by a brief description of the system itself. The use of the system as an aid to management of a large Air Force R and D laboratory with a wide range of technical responsibilities is outlined. The several resultant benefits, exclusive of those related to resources allocation, are delineated and are shown to range from technical program data retrieval to vastly more knowledgeable planning at the task engineer level. These side benefits are concluded to be equally as useful to management as the basic system itself, which was designed originally only to be an aid to resources allocation. (Author)

Review of the current approach to selling research and development (R and D) and an attempt to relate it to the workings of related marketing areas. Some fundamental shortcomings of the current practice are pointed out, and a new approach is suggested to the problem. A new concept is introduced in the approach to marketing R and D capabilities to the defense/space market which is based primarily on establishing capability managers as the focal point of the managing function. It is suggested that this is only one of the several new concepts that are needed to meet the challenges of marketing. B. B.

William H. Pound (Northwestern University, Technological Institute, Dept. of Industrial Engineering and Management Science, Evanston, Ill.).

IEEE Transactions on Engineering Management, vol. EM-11, Mar. 1964, p. 16-22. 7 refs.

Results of a field test of a procedure for evaluating research projects. The procedure, based on what is termed an expectedvalue model, considers the following decision elements: (1) the environment of the problem, (2) the decision maker, (3) his objectives, and (4) his alternatives. The decision maker's alternatives, in this case a number of potential research projects, are evaluated in the light of his objectives. The result of the procedure is a ranking of potential projects in terms of their expected values.

This procedure was tested in a research laboratory by having four decision makers evaluate a selected list of research projects. The resulting ranking of the projects was found to agree with an intuitive evaluation by the decision makers of the same list of projects. This gives an indication that the expected-value model may be useful in the complex area of research project selection.

Estimates are made of the departure from the desired level of research and development expenditure and the coefficients of important variables that cause deviations from the level. The main variables discussed are profits, sales changes, expected sales changes, and expected capacity changes. The statistical method used to estimate the parameters of the variables is multiple regression analysis. On the basis of the analysis, several hypotheses are proposed and discussed in relation to alternative hypotheses.

Presentation of information concerning the current conduct of DOD research and engineering activities. Management of research in the defense establishment is studied. It is shown that management provides the broad environmental influences wherein scientific programs can take place and technical decisions can be made which

culminate in major scientific breakthroughs. It is suggested that management should not restrict creative ideas in the initial stages of a program, but should provide wide latitude for research and experimentation. However, it is pointed out that this process of maintaining flexibility and a number of avenues cannot continue through the later processes of engineering and development. At these stages, objectives have to be clearly defined and parameters established; the decision-making process is then more clearly defined. The current problems of the DOD in performing its functions are reviewed, and the actual management of the Office of Defense Research and Engineering program is discussed in detail.
