Technical advance in aeronautical projects
(OP)
Does anybody have any idea about an easy way to measure the technical advance of the work, in a Detailed aeronautical Design? The released weight? but with the 100% of weigth released, still remains the assy and installation drawings, which doesn,t add weight.
Than you!!
Than you!!





RE: Technical advance in aeronautical projects
Iam not an aeronautical engineer,but the approach to % progress,is decided by you or your firm,i.e you devide the project activities into : 1. Design (0-100 % ) ,with a weight of say 30% of the total activities,so when it 100% complete ,this means (100% x 3o% )= 30% project completed
Next manufacturing weighted value (say 50% ),when all complete it is (100% x 50% ) = 50%
Now assembly ,weighted value (20% ),and only 50% is complete,so (50% x 20% )=10%
So total completion is 30% (design)+ 50% (manufacturing)+ 10% (assembly) = 90%,so another 10% is to be completed before you go on the runway !!
I hope ,I am in the right direction

For this topic law # XV applies:
LAW NUMBER XV:
The last 10 percent of performance generates one-third of the cost and two-thirds of the problems.

Use tasks small enough so that each is easily manageable but not so small so that the project structure becomes overly cumbersome. In construction a good rule of thumb is keeping tasks less than $10,000 or so. (Unless it is the delivery of a major item of equipment.) You may want some other criteria say man-hours of design time.
The weight to of a task can be based on the $ value, the man-hours spent on the task or some other criteria. You can also use multiple weighting of tasks. That would allow you to sat that the project is x% complete based on man-hours, y% complete based on dollars expended and z% complete based on number of critical tasks completed.
I don’t know anything about aeronautical design but I would think that released weight is not a good measure. The heavy components may be easy to design (and therefore take less man-hours) and the final small components may be light and time consuming to design.
