Sentence-Initial Connective Adverbs in Tech Writing

However, followed by a comma is the standard punctuation for a sentence-initial connective adverb. The pattern is: [Previous sentence.] However, [new clause.] A comma after "however" is mandatory in formal writing — it separates the adverb from the main clause and signals a brief pause. Option B (no comma) is incorrect in formal technical writing, though sometimes seen informally. Option C (semicolon) is only correct when "however" sits in the middle of two joined clauses: "Query speed improved; however, memory increased." Option D (dash) is journalistic style, not appropriate for technical documentation.

Therefore, the team chose… is correct when "therefore" opens the sentence. As a sentence-initial connective adverb, "therefore" is followed by a comma before the main clause. Option A lacks the required comma. Option C: when "therefore" appears mid-sentence between subject and verb, it takes commas on both sides: "The team, therefore, chose…" — the missing second comma makes option C wrong. Option D places the comma incorrectly after "chose." The punctuation rule: sentence-initial → comma after; mid-sentence → comma both sides; end of clause (before semicolon) → no comma needed.

Furthermore is the correct additive connective adverb. It introduces a second point that adds to, rather than contrasts with, the first: "It reduces server load. Furthermore, it prevents abuse." Both points support the same conclusion. Nevertheless is adversative — it would introduce a surprising contrast or concession, not an addition. Consequently and Hence are causal — they introduce a result or consequence of the previous point, not an additional benefit. In technical writing, the additive series runs: first = "First" / "To begin with"; additions = "Furthermore", "Moreover", "In addition", "Additionally".

Consequently correctly signals that the escalation was a direct result of the rollback failure. Causal connectives (consequently, therefore, hence, thus, as a result) introduce an outcome that logically follows from the previous statement. Furthermore would imply the escalation is an additional point, not a result. Nevertheless would imply that despite the failure, they escalated — this inverts the logical relationship. Likewise signals similarity: "Similarly…" — inappropriate here since escalation is a consequence, not a comparable action. In incident reports and post-mortems, consequently and therefore are the go-to causal connectives.

Nevertheless is correct here because the sentence structure is a concession followed by a counter-conclusion. The first two sentences present negative factors about the monolith; "nevertheless" signals: "despite these problems, we still recommend it." This is the classic adversative concession pattern: [negative point 1]. [negative point 2]. Nevertheless, [unexpected positive conclusion]. Therefore and Hence would be appropriate if the conclusion logically followed from the premises — but here the conclusion (keep the monolith) goes against the premises (debt, lack of experience), so a causal connector would be logically wrong. Furthermore would add another negative, not pivot to a conclusion.
