Does Efficiency Through Information and Communication Technologies (ICTs) have a limited scope of impact?

There is no doubt or argument that technology has made rapid improvements, especially with the emergence of Web 2.0.

 Within most industries, knowledge management systems and sharing knowledge are critical to an organization’s success (whether within education, healthcare, businesses and more). There are about 700,000 applications available for the apple IOS devices ranging in a variety of topics from books to business, education to entertainment, finance and half a dozen more. 
 
My intrigue in this question – does efficiency through information and communication technologies have a limited scope of impact – is two part. On the one side, in an effort to be more technologically savvy I have been sifting through recommendations and reviews of project management, task management and resource management apps. There always seems like another better, faster, newer option (and typically find out those other options immediately after purchasing another).

The other reason for my interest comes from the company I work for and the new evaluation tool launching this May. This is the third competency and evaluation tool implemented within a five-year period. Each time, all employees have to go through formal training and individual adoption. Undoubtedly the tool is “better” than the one before, but how long until it’s unnecessary to change every few years? Can we ever reach that point and if not, is there truly the ROI that everyone believes there to be? 
 
Two professors at the London School of Economics and Political Science explored this “dual perspective” between ICT infrastructure and the risk implementation. They recognize that the thought behind the change is that “the expected result in ‘re-plumbing’ of the corporation is a new, more agile, fast responding company, able to operate in a world of web…” (Ciborra and Osei-Joehene, http://is2.lse.ac.uk/asp/aspecis/20030035.pdf). 
 
What are your thoughts? I would appreciate any opinions, suggestions or resources. Thanks in advance!
