FAQs

Should we standardize on one AI platform?

No. Most successful businesses use 2-4 platforms strategically matched to specific use cases. The 15-20% efficiency gain from having "the right tool for the job" outweighs standardization benefits.

How do we prevent shadow AI usage?

Provide approved platforms that meet most needs. Establish clear policies. Make approved tools easy to access. Monitor spend for unapproved services.

What about data security across multiple platforms?

Choose enterprise platforms with SOC 2 compliance, implement SSO where possible, establish data classification policies, restrict sensitive data to most secure platforms.

Can we switch platforms later?

Yes, but consider: learning curve for team, workflow migrations, integration rebuilding. Start with flexible choices (ChatGPT/Claude) that minimize lock-in.

How much should we budget for AI per employee?

£2,400-£8,000 annually (£200-£670/month) depending on usage intensity. ROI typically 12-18x justifies investment.

Summary

The best AI for business depends on your specific needs, existing tech stack, and team capabilities. Most businesses benefit from multi-platform strategies matching capabilities to use cases rather than forcing one platform to handle everything.
