It is critical to take steps ensuring that required capacity is in place by the time it is needed.</p> <ul> <li><strong>Organic growth:</strong> Gaining new users and adoption</li> <li><strong>Inorganic growth:</strong> Adding new features or marketing campaigns</li> </ul> <h2 id="mandatory-steps">Mandatory steps</h2> <ul> <li>Create an accurate organic demand forecast.
