Platform Selection Process: A Five-Step Method
This section outlines a direct method to evaluate legal technology platforms based on your firm’s operational needs. Focus on measurable criteria to avoid bias and make objective comparisons.
Step 1: Define Research Needs and User Volume
Start by listing the specific legal resources your team requires daily. For example:
- Access to federal/state case law
- Availability of statutes or regulatory codes
- Secondary sources like legal journals or practice guides
- Tools for drafting legal documents
Next, quantify how many users will access the platform. High-volume firms (10+ users) often benefit from flat-rate pricing models, while smaller teams may prefer per-user billing. Clarify whether temporary access for paralegals or clients is necessary, as some platforms restrict user roles.
If your firm specializes in niche areas like tax law or intellectual property, verify whether the platform offers dedicated databases or advanced search filters for those fields. Platforms with broad coverage may lack depth in specialized areas.
Step 2: Test Interface Usability with Free Trials
Most platforms offer 7-14 day free trials. Use this time to:
- Perform common tasks like searching for cases, saving results, or generating citations
- Assess loading speeds for complex queries
- Identify unintuitive features (e.g., poorly labeled menus or hidden filters)
Involve multiple team members in testing to gather feedback. Prioritize platforms that require less than 30 minutes of training for basic operations. For example, determine whether:
- Search bars accept natural language queries
- Document folders auto-sync across devices
- Mobile apps replicate desktop functionality
Platforms with cluttered dashboards or slow search results reduce productivity over time. Compare error message clarity and customer support response times during trials.
Step 3: Compare Update Frequency for Legal Databases
Legal databases must reflect current laws and rulings. Ask vendors:
- How frequently case law and statutes are updated (real-time vs. daily/weekly)
- Whether updates include editorial analysis or only raw data
- How they handle emergency legislative changes
Platforms focused on litigation support often update case law within 24 hours of publication. Those specializing in compliance may prioritize regulatory updates. For example:
- A platform updated weekly may suffice for general corporate law
- Real-time updates are critical for tax law or securities regulation
Verify jurisdictional coverage. If your firm handles multi-state cases, confirm that all relevant jurisdictions receive equal update priority. Platforms with inconsistent update schedules for smaller states can create research gaps.
Check whether historical data is archived comprehensively. Some platforms remove older cases or statutes, forcing users to cross-reference external databases.
Pricing Models and Access Requirements
This section examines how Westlaw, LexisNexis, and Clio structure their pricing and manage access controls. You’ll learn how each platform balances upfront costs, scalability, and compliance with industry standards.
