I don't think it's necessarily a manufacturing process 
(although that's the most usual type of 工程)
E.g.
- 税制改革 工程表
- 日本再興戦略中短期工程表
- このモードは、主に開発工程で使用されます。

Kojien merges my proposed senses 1 and 3.
It doesn't really bother me whichever way. 
It seems pretty arbitrary how the senses are divided.
"stage of a process" ~ Kojien's sense #2:
1) 作業の手順。またその進み具合。
2) 生産過程を多くの段階に分けて分業を行う際の加工段階
