Tentative and hesitant get collapsed together constantly, and it's an easy mistake to make -- both signal some kind of uncertainty. But they describe different things entirely, and mixing them up produces a sentence that isn't grammatical English.
"Tentative" (in its business sense) describes the status of a plan, date, number, agreement, or conclusion. "Hesitant," "unsure," and "noncommittal" describe a person or a person's response.
Tentative describes a thing's status
The word attaches to an object -- a plan, a date, a figure -- and says it isn't locked yet.
"The migration window is tentative -- we're still confirming with the vendor."
The window has a status. Nobody's feelings are being described.
Hesitant, unsure, and noncommittal describe a person's stance
These words describe how a person feels or responded, not the status of a plan.
"The team is hesitant about the migration window -- they're worried it overlaps with the busy season."
"He was noncommittal when I asked for a date -- his answer avoided committing to anything specific."

The grammar trap
Because these words feel like synonyms, ESL learners sometimes reach for "tentative" in a sentence structure that only "hesitant" can grammatically fill.
Wrong: "I am tentative to approve the spend." Right: "I'm hesitant to approve the spend." (describes the speaker's feeling) Also right: "My approval is tentative." (describes the status of the approval)
"Tentative to do X" isn't a pattern English uses. "Hesitant to do X" is. If you want to keep "tentative," it has to attach to a noun -- the approval, the decision, the plan -- not to "I."
Tentative can describe a person's manner -- but differently
Tentative can describe how a person comes across, as an exception to the rule above -- but it uses a different structure than the "hesitant to do X" frame.
"He sounded tentative in the review, like he wasn't sure of his own numbers."
This describes the speaker's manner, not the status of a plan -- but notice it's "sounded tentative," not "was tentative to say." The "*tentative to do X" frame belongs to neither use.
The rule
Ask what the sentence is actually describing: the confirmed-or-not status of a plan, date, number, or agreement (tentative), or a person's stance, feeling, or reluctance (hesitant, unsure, noncommittal). If you're about to write "tentative to [verb]," stop -- that frame doesn't exist. Either switch to "hesitant to [verb]" for the feeling, or rephrase around a noun ("my approval is tentative") for the status.
Practice scenarios
Practice choosing between tentative and hesitant/unsure/noncommittal in situations like:
- describing a date's confirmation status versus a team's feelings about it
- catching the "*tentative to do X" grammar error before sending
- rewriting "he was noncommittal" versus "the offer is tentative" correctly
Useful practice phrases:
- "The date is tentative -- still confirming."
- "The team is hesitant about the timeline."
- "I'm hesitant to approve this without more data." (not "I am tentative to approve")
- "My approval is tentative, pending the final numbers."
Tentative describes the plan. Hesitant describes the person. "Tentative to do X" describes neither -- it isn't a pattern English has.
