Client Data Trust Handoff (Handoff)

Client Data Trust Handoff (Handoff)

1. 01

   Freeze the client's source systems for a 48-hour read-only window before extraction

   Ask the client to pause bulk imports, CRM merges, and list uploads so the snapshot you hand over reflects one consistent state rather than a moving target.

2. 02

   Profile every inbound table against six checks: completeness, uniqueness, freshness, schema drift, referential integrity, and value distribution

   Record pass or fail per check with the row counts behind each verdict. A 4.9 percent duplicate rate on a 120,000-row contact table is a finding; 'some duplicates' is not.

3. 03

   Separate defects into three buckets: fix now, fix at source, and accept with a documented caveat

   Formatting and casing issues belong in the first bucket. Anything requiring the client to change a form, integration, or upstream process belongs in the second and needs an owner named in writing.

4. 04

   Run the cleansing pass in a sandbox copy and diff the output against the original

   Browser-side tools such as CleanMySheet handle duplicate removal, date standardization, and phone formatting without the file leaving the machine, which keeps sensitive client records out of third-party storage during the trial pass.

5. 05

   Reconcile the cleaned dataset against the client's own reporting totals before anyone builds on it

   If the client's dashboard says 8,400 active accounts and your cleaned table says 7,910, resolve the 490-row gap now. Unresolved deltas resurface as disputed invoices three months later.

6. 06

   Write the handoff memo with the trust score, open defects, and the monitoring thresholds you will enforce

   State the freshness SLA in hours, the null-rate ceiling per critical field, and the volume band that triggers an alert. Vague commitments like 'we watch the data' do not survive a client-side review.

7. 07

   Walk the receiving team through the memo live and get written sign-off on the caveats

   The person who inherits the pipeline must confirm they understand which fields are unreliable and why. Verbal acceptance is not a handoff.
