To this effect, you can review their case studies and portfolio to cross-verify the verbal assurances and guarantees that the company in question may have offered you right at the start.

Next, check which project management methodology they prefer to adopt, such as Agile, Scrum, or Waterfall, and confirm whether you're comfortable with that approach.
