The growth of Bitcoin
Bitcoin an example where the security of block chain transactions is measured by the individual computing power vs. all the legitimate modes computing power to solve, proof of work puzzles; furthermore
large scale computing power may be better used being a bitcoin miner rather than forking the chain with a fraudulent transaction.
A good explanation of how this works is at https://www.khanacademy.org/economics-finance-domain/core-finance/money-and-banking/bitcoin/v/bitcoin-security-of-transaction-block-chains
There is another security limit based on the lifetime of current encryption technologies. Encryption has 50% chance broken by 2030 due to advances in quantum computing.

Technology may be finally forcing IT to focus on its proper support role in the business.
Cloud offerings are enabling Shadow IT for users needing to get the job done.
Users have rightfully complained that IT is more accustomed to saying no than empowering the user.
IT may find itself outsourced to the cloud.
An objective scorecard comparing cloud services to on premise offerings clearly favors the cloud.
The typical IT reaction to these developments is to falsely claim that on premise is needed for security, to protect sensitive information, to remain in business (IT) control.
A smarter tactic would be to recognize reality and actually champion Shadow IT efforts and the move to the cloud.
In that regard moving SharePoint from on premise to Office 365 is the future of SharePoint.
Although on premise SharePoint offerings will continue with the 2016 and future editions, development work should be to the new client side app model.

The cloud has matured and will host most corporate and government data centers and applications.
The following highlights some of the numbers
Even big Silicon Valley companies are embracing cloud driven application development.
The software development process is now continuous for feature enhancement and security reasons.
Major Microsoft products including SharePoint and Exchange are more effectively delivered and secured through Office 365.
Accordingly this blog will refocus on these developments, the new IT System Basics.

Dimensions of Information Quality
1) Accuracy – Has it been checked or approved?
2) Reliability – is the source credible?
3) Presentation – simple, readable?
4) Timeliness – is it currently applicable?
5) Completeness – are the essentials covered?
6) Highlights Main Issues – fair and balanced?
7) Relevancy – on topic?
8) Usable Format – reusable electronic form?
Factors that reduce Quality:
1) Incorrect data
2) Poor credibility
3) Complex presentation
4) Out of date information
6) Focus on tertiary issues
7) Irrelevant – off point
8) Sloppy formatting
Typical examples leading to misinformation:
Old content never expired
No content approval process
No metadata tagging
Deep hierarchical structures
Poor information governance
Information governance increases the quality of information and reduces costly errors,
principally due to misinformation.
The business relies on utilizing the right stuff (high quality information)
