Technology is more than just

‘‘stuff’stuff’Includes: Hardware - ‘stuff’

AlgorithmsTechniquesSoftwareSystems etc....


Our developments use.....Our developments use.....

Some very new technology – some not even available yet! –

Projected for SKA build time

Need to understand Need to understand

and control and control RISKRISK


No!!No!! like stress:

SomeSome is good (for now)

But, too much is BADBAD


‘‘Goldilocks’Goldilocks’ RiskRisk

& friends: fallback + upgrade

Tech. Innovation

Better performance

More/new science

e.g wide-area comms data rate:

1Gb 10Gb 100Gb

Concept: High risk

Development: Understand risk

Build time: Minimised risk

Now


Controlling RiskControlling Risk

Risk Status assessment - ongoing• Empirical - educated guess

• Formal - structured risk assessment

→ ‘Retiring’ RiskRetiring’ Risk over time

Risk Understanding:• Follow trends – commercial, industrial

• Demonstrators → pathfinders → initial phase

LO FAR

e.g.


Some Some ‘Formal Technical ‘Formal Technical Readiness’Readiness’ Questions..... Questions.....

1. Has an identical unit been successful operationally in an identical configuration?

2. Has an identical unit been demonstrated on an operationally, but in a different configuration/system architecture?

3. Has an identical unit been mission qualified but not operationally demonstrated?

4. Has a prototype unit been demonstrated in the operational environment?

5. Has a prototype been demonstrated in a relevant environment or surrogate platform?

6. Has a breadboard unit been demonstrated in a relevant environment

7. Has a breadboard unit been demonstrated in a laboratory (controlled) environment?

8. Has analytical and experimental proof-of-concept been demonstrated?

9. Has a concept or application been formulated?

10. Have basic principles been observed and reported?

11. None of the above NASA etc.


A few SKADS Risk thoughtsA few SKADS Risk thoughts

• EM simulation MM• System noise – LNA, matching H H →→ MM• Beamforming – analogue & digital HH• Volume manufacturing MM• Signal transport LL• Calibration HH• Post processing HH• RFI suppression MM• Software - System control and processing M M →→ HH

Need to start some retirements...


Workshop 2008......Workshop 2008......

• SKADS will be nearing completion .....• Assess risk in our Tasks for final reports and future work,

so:

All Tasks will perform a

And finally.....And finally.....

...new technology & risk is a delicate balance:
