Following the excellent idea proposed on Venger's old-school gaming blog, I have adapted his "Spectrum of Awesome" table to work with Traveller's 2d6 idiom as opposed to Venger's original percentile system. Visit his link to get the basic concept, which I won't repeat here.
Note that my probabilities are not exactly the same as his, and since 2d6 has 11 "bins" that do not map directly to Venger's 9 categories, this is not a direct conversion anyway.
I've provided two variants - Classic Traveller and Mongoose Traveller. In both cases, I've "repurposed" existing game mechanisms to get a similar effect.
The CT version applies SoA principles to CT's reaction table. If you determine that the players have advantage, add a +1 DM to the roll. And naturally, apply a -1 DM for a disadvantage. The original reaction table has "critical fail' rolls, which I have retained. It does not have "critical success" rolls, so I've left them out as well. Complications should be things like, "got away but dropped something important" and mitigating factors would be things like, "captured, but were able to hide a weapon on you before you were thrown in jail".
Spectrum of Awesome, Classic Traveller Style
2 ~ critical failure, worst possible result
3 ~ failure, critical failure on 5+
4 ~ failure. critical failure on 8+
5 ~ simple failure.
6 ~ borderline failure, impose mitigating factors
7 ~ stalemate, mixed result; some success and some failure
8 ~ borderline success, impose complications
9 ~ minor success
A ~ solid success
B ~ high degree of success
C ~ critical success, best possible result
The Mongoose Traveller version is really just the standard MgT task roll against an average difficulty.
Spectrum of Awesome, Mongoose Traveller Style
Throw 2D, Average Difficulty
6+ ~ critical success, best possible result, +2 to relevant follow-on tests
1 to 5 ~ Average success, +1 modifier for relevant follow-on tests
0 ~ success with complications
-1 ~ failure with possibility of recovery by accepting complications
-1 to -5 ~ Average failure
-6 ~ Exceptional failure
