What a finished MKT-443 Topic 3 identity resolution analysis looks like
A count that surprises the center's board opens the finished analysis. Its four systems hold about 126,000 patron records, and after matching, those records describe an estimated 71,000 people, every figure labeled illustrative. The analysis shows how that estimate was reached. Exact matches on email address resolve the easy cases. Probabilistic matching then scores pairs on name similarity, postal address, phone number and card token, and a pair above a set score is merged automatically. A band of uncertain pairs goes to a review queue, since a subscriber named Pat Moreno at one address might be two people. Households are handled as a separate layer above individuals, because a couple shares a subscription but gives separately. The analysis ends by stating which source wins for each field when records disagree.
How an MKT-443 Topic 3 example is structured
The analysis runs from sources to rules to errors to governance. Its first section describes each system, what it records about a patron and which identifier, if any, it shares with the others. A profiling section shows how the same person tends to appear differently in each: a nickname at the box office, a work email for donations, a phone number only in the parking app. The matching section sets out the exact rules first and the scored rules second, with the thresholds chosen and the reason for each. An error section compares the two ways matching fails and what each costs this organization. The household layer follows, linking individuals without merging them. A survivorship table then says, field by field, which source is trusted when two disagree. The final section makes one person in the development office responsible for the review queue and sets how often thresholds are rechecked.
One patron, four versions
A nickname at the box office, a work email in the donor file and only a phone number in the parking app show why no single field joins the systems.
Exact rules before scored ones
Matching on email resolves the easy pairs first, and scored comparison of name, address, phone and card token handles the rest under stated thresholds.
An uncertain band sent for review
Pairs scoring between the two thresholds go to a person rather than a rule, because a shared surname and address can belong to a parent and an adult child.
Wrong merges weighed against missed ones
Merging two donors hands one of them the other's giving history, while missing a match sends a major donor a first-timer discount, and the analysis prices both.
Households linked, individuals kept
A couple shares one subscription and gives separately, so the household sits as a layer above two intact records instead of collapsing them into one.
Survivorship decided field by field
When records disagree, the donor database wins for legal name, the email platform for contact preference and ticketing for seat history, each by a stated rule.
Where marks go in MKT-443 Topic 3
The first mark lost usually belongs to a paper treating the single view as a storage project, one big database to pour everything into, since loading four sources into one place resolves nobody. Matching rules described without thresholds leave the reader unable to judge how aggressive the merge was. A frequent gap is counting only missed matches as errors; a false merge can be worse, and for a donor it can be embarrassing in writing. Drafts that fold couples into one record because they share an address erase the separate giving the development office depends on. A precise count of unique patrons overstates what probabilistic matching can deliver, and the stronger papers report a range. Where no role owns the review queue, uncertain pairs pile up and the view quietly degrades.

MKT-443 Topic 3 questions, answered
What is the difference between deterministic and probabilistic matching?
Deterministic matching joins records only when chosen fields agree exactly, such as an identical email address. Probabilistic matching compares several fields, scores how strongly they agree, allowing for spelling variants and partial addresses, and treats pairs above a threshold as the same person. The first is precise and misses a great deal; the second finds more matches and occasionally merges people who are different, which is why the example uses both.
Why is a false merge sometimes worse than a missed match?
Because a missed match leaves two incomplete records, while a false merge creates one record that is confidently wrong. At an arts center, merging two donors can put one person's gift in a thank-you letter to the other, which damages trust in a way no duplicate mailing does. Organizations handling giving or health records usually set stricter thresholds for exactly this reason.
What is a survivorship rule?
A rule deciding which value is kept when matched records disagree. One source may hold the most current address, another the legal name, another the communication preference. Survivorship can favor the most recent entry, the most trusted system or the most complete value, field by field. Without stated rules, a merge keeps whichever record the software processed last, which is rarely the best one.
