In this case the instruction card simply says: — "Standard Instructions 



No. :" 



This standard planning has been carried out in a number of important 

 matters. 



In design work the planning is assisted by a book of standard procedure 

 developed over a considerable number of years. 



The planning comprises for each individual design: — 



(a) Analysis into component jobs in both rooms. 



(&) Estimated curve progress on plans on a basis of time. 



(c) Estimated curve progress on specifications on a basis of time. 



(d) Estimated curve progress on calculations on a basis of time. 



The above, of course, all applies to the actual design after the preliminary 

 work has been done and the type decided on. 



Preliminary work has been much facilitated by the use of forms, stand- 

 ard curves and compiled data, but being to some extent in the nature of 

 experimental work is not subject to the exact planning possible in the later 

 stages. 



Curves and Charts.— In making these curves reference is had to previous 

 date for similar jobs, foreseen interruptions allowed for, allowance made for 

 leave required by law, sickness, etc. 



A sample of such a curve is shown on Plate 28. On this estimated prog- 

 ress curve, which is kept in view, is plotted the actual progress from time to 

 time so that direct comparison and estimates may be made as to the degree 

 of completion, probability of finishing at time set, necessity for overtime 

 work, etc. 



One of our most difficult problems arises from the fact that until the 

 naval bill passes we never know what the program for the year is to consist of. 



Usually we have sufficient information from the Secretary of the Navy's 

 requests of Congress to approximate to it and to plan the work on the com- 

 ponent units, but as soon as the bill passes we must fit these units together, 

 according to the number given us, into a plan for the whole program. 



A part of a chart for such a program is shown on Plate 29. 



At each leading man's desk is kept a chart on which is indicated cur- 

 rently by red and blue areas the proportion of each component of the job 

 that has been completed. These areas are based on a total area representing 

 100 per cent and are so made that, by inspection, an immediate glance shows 

 within 5 per cent of the correct amount completed. A sample is shown on 

 Plate 30. 



For ship design and ship calculation we have deduced a standard chart ; 

 for lesser jobs we either make a special chart or do without it.
