The diagram the bottom is like 25illustrate some points declines mean stronger dependencies and thin lines me week dependencies and number lines is also important so on the left I've got a lot of dependencies and a lot of big thick ones so for example they the town rightmost boxes the two like most molecules on the left diagram 3 Hallows going PMP down 3 somewhat weak dependencies toward the center like us and think it depends show on the line got an improved design whether where the number dependencies coupling be reduced okay now I only have deadlines and fuel margins are connected and no place to I have multiple connections between the same large so number connections and the strength to the connections import both simple and together number and string going to juice number and strength wanted the design patterns we talked about.
