Software delivery is not a house build

Why can't we deliver  software  as easily as building a house  ?  The economic answer lies  in how much more we pay software professionals !  The market forces decide the price of a commodity based upon a lot of factors like ease of making , scarcity, complexity etc. That's it ! as one of my  work mates would say ...

Software is complex. Fathom this - an operating system is a complex piece of software with millions of lines  of code which interact with other component's of software. Bug in a line of code can lead to the entire product malfunctioning.

Couple that with unclear & changing requirements and software delivery does not look like a house build. Add to this timelines. As a general rule of thumb, based on experience a software project  takes 2-3 times more than initially envisaged. A house build is not prone to that level of error.

Good developers are scarce & come at a premium. They are the fulcrum that transforms a project into product.

It becomes clear that by treating software delivery tantamount  to a house build  will likely set you up for failure.
