Those Undertaking The Development and Implementation of The NEHRS Were Always Kidding Themselves. Here is Some Important Evidence About What Went Wrong From The Outset.

For some time I have been mulling about the issue of IT Project complexity and what it means for large projects in general and the NEHRS is particular.
My interest was spurred by the following short quote from a presentation on top IT trends:

Gartner's Top 10 Tech Trends Through 2015

I.T. Complexity

Pointing to Glass's Law (sourced to Roger Sessions of ObjectWatch), which states that "for every 25 percent increase in functionality of a system, there is a 100 percent increase in the complexity of that system," Gartner predicts there will be an emphasis on the ability of an enterprise to get the most out of I.T. money spent.
Read about the other 9 here:
Reading this made me think of the PCEHR Con-Ops and just how many function points there were and how this must have inevitably weighed the Program down with crushing complexity.
Looking for more information of Glass’s Law led me to this really awesome presentation from Roger Sessions himself.

Web Short: The Relationship Between IT Project Size and Failure

Large IT projects have bigger budgets than small projects. They also have more formal approaches to tracking milestones and budgets. Does this make them more likely to succeed? It turns out that there is a relationship between the cost of a project and the chances that that project will succeed, but it isn't what you might think.
Watch the presentation and then leave a comment.

You can (and should I reckon) view the whole presentation here:
A few points from it:

Grim Statistics: 

An estimated 85 percent of government IT projects are late, over budget or both. - The Pew Center on the States, “Focus on Performance”, 2010
The presentation then goes on to define project success:

IT Project Success Criteria

1. Accurate determination of business needs.
2 . Accurate determination of optimal schedule.
3. Accurate determination of optimal cost.
4. Delivery of all of the above.
And finally for my purposes then goes on to point out that the evidence on what is too big for success is really alarming:
There are two recent studies cited:
(Standish) 2009 Chaos report published by the Standish Group
and
(Sauer) The Impact of Size and Volatility on IT Project Performance by Chris Sauer, Andrew Gemino , and Blaize Horner Reich, Comms of the ACM Nov 07
In broad terms what both studies concluded based on what actually happened in the real world was:

Sessions’ Law of Size IT

  • Projects less than $1M will probably succeed, regardless of how poorly managed they are. 
  • IT Projects between $1M and $10M can succeed, if they are very carefully managed.
  • IT Projects over $10M will probably not succeed, regardless of how well managed they are.
The presentation then goes on to discuss the issues of project breakdown, dependencies, timing and so on - and how this is critical.
What can be concluded from all this:
Firstly you need to get your requirements right - I would not say this was done - and then with something like the PCEHR you need very expert optimisation approaches to make the whole thing workable and manageable - if indeed you are still wanting to go ahead at scale - rather than at much greater simplicity.
For those with the stomach this article makes very interesting reading:

How to Spot a Failing Project

Often, the difference between success and failure is spotting critical early warning signs that a project is in trouble. Here are a few ways to identify the symptoms.

These paragraphs or two says it all.

“Looking for Warning Signs

While the Chaos surveys give reason for optimism, they leave little room for complacency. Nearly one in five IT projects still fails absolutely and more than two in five are partial failures.

What is perhaps more troubling is that the bigger the project, the worse the problems. "Seventy-three percent of projects with labor cost of less than $750,000 succeed," Jim Johnson says. "But only 3 percent of projects a with labor cost of over $10 million succeed. I would venture to say the 3 percent that succeed succeeded because they overestimated their budget, not because they were managed properly."

and this reminds you of what among the warning signs?

A "No-Bad-News" Environment

"This is a really tricky cultural thing," says Raj Kapur, executive vice president of the Center for Project Management, a software project management consultancy and education firm in San Ramon, Calif. "Everyone is allergic to bad news." As a result, it's all too easy to develop a culture where bad news is slow to percolate upward—which deprives management of vital, if unpleasant, information.

"You have to provide an environment where bad news is accepted," says Kapur. "That's critical, and it's not the job of the team members. It's the job of the leader." And by extension, the CIO.”

None of this is all that new - but it does seem to have been rather forgotten by DoHA and NEHTA. The senior managers just should have known better and been more realistic about how they went about things. They were not and so here we all are!
