time-to-market pressure in software development

It is rather amazing that there appears to be a consensus among industry experts that there has not been any improvement in code quality over the past 30 years or so despite the development of a vast number of new tools and languages. It is true that the size and scope of the average application has grown by leaps and bounds. But most likely, the primary contributing factor to these kind of quality problems is the prevalent time-to-market pressure in the software industry which is typically coupled with severe underestimation of time and resources required for projects.
