Whats Missing / Wrong

Bloated Layouts and Functionality Seperately packaged products

Training course required

Possible abuse of data Results unclear

Doesnt give clear picture of resource

management

Risks

The algorithms I develop are ineffectiv The new algorithms bring nothing new

advantageous to the table

Availability of data sets Full application proves to be too much

Fallback

The interface Ease of implementation

The interface itself may bring something new

table

Try again with new algorithm

Framework should be able to be recycled

Longer term project
