With due respect to Mr Gertrude he must have skipped the real estate industry while writing this famous quote!
As recently a study was undertaken via a renowned Management Institute in the country for a US software giant corporation. Its about use of software as well hard ware in Real Estate /Construction industry or call it IT ie Information industry in the country. As being one of the largest employment generating industry & turnover even higher than Automobile industry yet the use of computer & related services is not even 2% of its turnover!
Many will be surprised but as with whatever limited exposure I have in last 20 years in real estate industry, I will say its failure of Computer Industry as well the Real Estate Industry combined! If Computer Industry hasn't been able to understand the exact needs of this business then Real Estate Industry wasn't ever truly open for the newer technology & laid their demands clearly!
Basically software industry is indirectly is a parasite in itself! No offence all software guys but it needs a customer industry to adopt their knowledge which in end is used to improve the parental industry! Here what has happened as the real estate has been never standardized so naturally IT industry has never been able to understand what this industry needs! And as the land prices is the only thing in world which keeps on rising without doing anything they never have been keen on improving the business with assistance of IT industry. Also real estate has got least of technical personals & don't required any licence or that sort of thing so obviously they prefer to stick to orthodox methods of construction !
I remember even in my Eng college days civil guys were more comfortable with T square for drawing than using drafting equipment,which other branches were frequent with!
