Historical story

Is describing a process past tense?

Not necessarily. Describing a process can be done in any tense, including past, present, or future. For example:

- Past tense: "The company developed a new product last year."

- Present tense: "The company is currently developing a new product."

- Future tense: "The company plans to develop a new product next year."

So, whether describing a process is past tense or not depends on the specific context and the speaker's choice of tense.
