Term Project

For your emerging information processing technology : Be sure you address how likely will that technology be adopted at large in the next year?

The next 5? The next 10? Predict how the technology will effect people and society at large after 1 year. 5 years.

10 years.

You could use a timeline to base your predictions. Feel free to update your timeline with new material you find useful.

Chapter 7 should be very helpful as well.

Paper Minimum 1 page per subject/chapter in book 1 paper section per subject/chapter Each Section should follow the same guidelines as our 1 page

paper assignments, outside references included.

Microsoft Vista

Vista was designed to increase security of XP. Most people still preferred XP Vista has hardware requirements? Vista ran slower than XP

Learn from your mistakes!

Don’t release a product if its not ready! Follow the shifting of Technology! Have a business model! Pricing your product is as important as the idea!

Risk

What is it? Chance of it happening?

Random, Historical statistics, Analysis

Give examples of risks with computer systems


© 2009 Keith A. Pray 3304/19/23

Predicting Risk

What are the factors? Enough data to be statistically significant? Can you reduce or increase your own risk?

Chance Severity


© 2009 Keith A. Pray 3404/19/23

Reliability Of Statistics

Are other factors controlled? Is enough time covered? Is all data reported?


© 2009 Keith A. Pray 3604/19/23

Risk-Benefit Analysis

What could go wrong? How likely is it? How costly are the consequences?


© 2009 Keith A. Pray 3704/19/23

Limitations to Risk-Benefit Analysis Hard to quantify probabilities Hard to quantify costs Who bears the costs? Are the potential benefits worth it?


© 2009 Keith A. Pray 3804/19/23

Some Measures

Mean Time To Failure (MTTF) Mean Time Between Failures (MTBF) Mean Time To Repair (MTTR)


© 2009 Keith A. Pray 3904/19/23

Relying Too Much

Limits of modeling reality Limits of precision Limits of algorithms Limits of interpretation


© 2009 Keith A. Pray 4104/19/23

Producing Good Software

Good specifications Good usability Good design Robustness Good implementation Testing
