Start with the outcome you want, not the tool.
Map the process first
Write down how the work really happens today, including the awkward exceptions. A tool chosen without this step usually fits the demo better than it fits your business.
Buy, configure or build
Buying off the shelf is fastest when your needs are common. Configuring a flexible platform suits needs that are slightly different. Building suits needs that are truly specific. Count the full cost of each, including maintenance and the time your team will spend learning it.
Prefer tools that connect
Choose tools that integrate with the ones you already use. Data that can move freely saves more time than any single feature.
Decide who owns it afterwards
Name who maintains the system after launch, who can change it and what happens if that person leaves. Unowned systems decay quickly.
Run a small pilot
Test with real work for two weeks before committing. A pilot tells you more than any demo, and it is far cheaper to change course early.
