Abstract

Technological developments, such as miniaturization and convergence have astrong impact on the form, function and content of consumer appliances. Theappliance makers are struggling with the consequences, especially with theexponential increasing SW effort.The trends and the impact on consumer appliances are discussed. Then thesoftware effort problem is analyzed and solution directions for the SW productivityproblems are explored.
