Hi Guru, What exactly is the ostrow Model ? How useful is it to the clients ? Is it the last word ? Thanks

The Media Guru Answers(Friday, September 03, 1999 ):
The ostrow Model with which the Guru is familiar is a grid used to set the correct level of effective frequency at which plans will be evaluated.

20+ factors relating to competitive climate, product involvement, clutter, commercial length, commercial pool, etc are each rated on a scale, say from 2 to 6, which is then averaged to set the frequency level.

Is it the last word? Is it useful to clients? There is always another theory about anything. The usefulness is in creating a reational, well thought-through basis for establishing communiations goals, so that planners can present a logical approach to clients. The approach makes good sense, for those who follow the effective reach style of planning.

Dear Sir, regarding effective frequency there are some tools like ostrow's grid. But I could not find any explanation about how to set effective reach level. Using a grid one can find a frequency level like 4+ but what the effective reach should be set at this freguency level? What are the considerations?

The Media Guru Answers(Wednesday, June 09, 1999 ):
There is a lot of judgment here, plus the realities of budget. When setting an effective reach, saying only those reached at least "x" times count. So first, how high a reach can you afford? Of course with flighting this answer can vary, too. The Guru basic rule of thumb is to start by effectively reaching most of the target; 50 reach or better.

Dear Guru. I am a media planner in India. Need some information on latest effective frequency models. The ostrow model as described in the Scissors and Bumba is the only one I have seen. Are there any other models developed? Also it would nice if you could pass on some info on recency planning theory.

The Advertising Research Foundation library would be the best source for alternative models.

The Guru has often discussed recency. Click here to see past guru responses on recency planning
