Dear John: 

Enclosed is a copy of our study on the effcctivem: ss of ABM 

collectors. As you know, this study was undertaken at the request 

of the Bureau of the Budget in 1967 and the addressees of this letter 

were established as a committee to oversee its preparation. I would 

like io lake this opportunity to express the thanks of the Director of 

Central Intelligence and my own to those who have contributed to this 

difficult, complex and protracted work. ~---------~ deserves 

our appreciation for his patient and competent efforts to bring it to 

completion. 

Obviously the study has its limitations. A methodology has yet 

to be devised which will appeal to everyone as ideally calculated to 

provide an objective basis for the evaluation of intelligence activities. 

The particular methodology developed in this study can certainly be 

attacked as itnperfect. We would welcome proposals from any component of the community for new or different approaches to the 

evaluation problem gene

£ive years in the future with different combinations of existing and 

programmed collection systerns; and how well the indvidual and 

several classes of collectors do or might be expected to do. Moreover, 

the study has the virtue of providing specific quantitative n:easures 

of a kind not heretofore available to the intelligence community. 

Of possible consequence for the longer run is that the conceptual 

approach has potential for broader application. 

This last consideration brings nie to Recommendation 4, which 

proposes application of a comparable conceptual approach to all intelligence needs and all collection systems. To :facilitate consideration of 

this Recommendation, I have also enclosed one tentative structure of 

intelligence needs and their relative values. 

I should greatly appreciate yo~r views and con1ments on the 

study and its recommendations (which can be addresi:led to~------~ 

and any proposals that occur to you for irn.p:::oving its methodology or 

by way of specific alternatives. Hopefully these corrL'Y1ents will reach 

us before the end of Novernber. The Director of Central Intelligence 

has asked me to submit the study to the Kational Intelligence Resources 

Board with a request for their comments and recommendations. 

Sincerely,
