The answer to this question depends a great deal on
the demand for the products and how well the target audience has been
identified.
Marketing results improvements are typically more effective
when developed in a process of some kind rather than results improvements
that depend mostly on luck, trial and error, or random, fits and starts
promotional activities.
If marketing results measurements and tracking capabilities
are in place, the ability to test various marketing strategies and
track the results, allows marketers to discover the "cause and effect"
of their marketing strategies. Once a strategy is proven effective,
further development and testing can improve strategy effectiveness
even more.
Methods to improve Direct Marketing Results rely on
the same methods used
to discover major inventions or medical breakthroughs - a "laboratory
approach" that employs the Scientific Method.
