1) Utility tree
2) Develop some tactics/techniques
Action Item:
Fri evening – Attributes. Talk to prof Sam regd attributes
Take one attribute and divide them into sub-attributes
Different levels of abstraction is present – difficult to judge coverage
One stakeholder in different categories – do not club them together
Schedule appointment with Prof Sam.
Come up with encoding techniques – map value to the aspect and decision – append all
these values and attributes in a single Value Network diagram.
Value Delivery Network – road map
Each decision – diff types of stakeholders
Different priorities during diff points of the life cycle – keep notes about the rationale
How do u know that the attributes list is complete?
Test the model
- Talk to the stakeholders and see if they agree
- Check if the expected results align with the obtained results
Spectators –
Camera – viewing the thrill in robot ramping - value to spectators
Questions:
1) Stakeholders - Define, different types of stakeholders (supplier vs investor – are
we buying the engine or is it sponsored by the supplier himself?)
2) We have come up with the stakeholder group. But we are unable to exactly
identify the stakeholders? Representation of each individual stakeholder
3) Attributes
4) What next? – go in-depth into engine selection or look at another perspective and
work on it in parallel as well
5)
Safety:
-
Safety of the fuel used
Priority in relation to Importance
Availability – in terms of cost, in terms of money – can be considered as a constraint if
the reqd resources are not available
Sample trade study – look into it
Quality attributes – in terms of value propositions, cost-benefits, etc..
Sustaining engineering – re-engineering systems to utilize them again..
Conflicts among stakeholders (Expectation management)
1) Looking at the value propositions
2) Know more abt the value propositions and check where the risk creeps in – work
on that
3) Keep interacting and explain things – regularly remind them of the requirements,
thresholds, etc..
Discussions on 08-Jun-2006:
Attributes (High-level):
1) Safety
- Usability (control)
- Security (to prevent stealing of robot – monitoring using camera control)
- Environmental
i. Noise pollution
ii. Emission
(Fuel choice)
2) Performance
- Speed
((Fuel choice)
- Reliability
- Availability (considering it as a constraint)
- Maintainability
3) Modifiability
- Integrability (required when we integrate the engine along with the other
machine parts to build the robot)
4) Profitability
- Cost ((Fuel choice)
- Reputation
- Reusability (required if we have to reuse it for the next race)
