    Week 1; shared with Daniel Achterberg, VP Customer Experience

    Review how the helpdesk runs: queues and agent groups, use of macros and knowledge articles, SLA targets and breaches, and what makes tickets slow.

    Subject: Helpdesk operating review — what I need this week

    Hi Ben,

    Daniel and I need a baseline read on how the helpdesk actually runs, so we can walk into our first leadership review with a clear picture instead of impressions. This feeds our decisions on how we staff/structure agent groups, where we invest in macros and knowledge base content, and whether our current SLA targets are realistic. Given you only get a handful of reports a night, here's what matters most, roughly in priority order:

    1. Where is ticket volume concentrated, and are the right groups/agents carrying it? I want to see how load splits across our queues and agent groups, and whether staffing looks balanced against that load — this feeds a near-term staffing/routing decision.
    2. Are we meeting our SLA promises, and where do we miss most? I want to understand how often we breach first-response and resolution targets, and whether certain priorities, groups, or times are the repeat offenders. This is the headline number Daniel will want for the review.
    3. What actually makes a ticket slow? I'd like a sense of what separates a ticket that resolves quickly from one that drags — whether that's certain topics, channels, or simply sitting unassigned — so we know where to intervene first.
    4. Are macros and knowledge base articles pulling their weight? I want to know how much agents lean on canned replies and how the knowledge base is doing with customers (are articles helping people avoid a ticket, and are the ones we have actually rated as useful) — this feeds a content/investment decision for next quarter.
    5. (If there's room this week) How satisfied are customers coming out of resolved tickets, and does that satisfaction track with the SLA and speed picture above, or is something else driving it?

    No need to go deep on all five — pick what fits in the nightly slots and flag anything surprising even if I didn't ask directly. Keep it at a level Daniel and I can act on quickly; we'll dig deeper live once we see the numbers.

    Thanks, Mia

    A note from the VP Customer Experience, Daniel Achterberg

    Subject: A few things I'd like your review to cover

    Hi Ben,

    As you dig into the helpdesk review this week, a few questions from my side:

    1. Where do tickets actually get stuck? I'd like to understand which queues or agent groups have the slowest response and resolution times, and whether that's a staffing/routing issue or certain ticket types being inherently harder.
    2. Are we actually meeting the SLA targets we've set, and for the ones we miss, is there a pattern (specific merchants, priorities, time of day/week)?
    3. Are agents getting value from macros and the knowledge base, or are they re-typing answers every time? I'd like a sense of whether better self-serve content or canned responses could take load off the queue.

    If you find anything that points to a specific merchant or category driving a disproportionate share of the pain, flag it even if it's outside these three.

    Thanks, Daniel

  3. Ben Carter plans the night

    The analyst · week 1, night 3, request 3 of 3

    Before trusting any more SLA numbers, I need to close the risk two separate engineers flagged independently: breach_kind is a free-text column with no enumerated codes, and both guessed 'first_response'/'resolution'. If that guess is wrong (or there's a third kind, or duplicate breach rows per ticket), every breach rate I've reported so far — including the 37.7%/20.3% headline — could be off. That's slot 1 tonight, cheap but non-negotiable before Friday's memo. Report 1 from tonight's merchant cut also showed something worth flagging: our three biggest merchants (Cragsley, Marrowby & Vane, Studio Vrij, 34% of volume) all post first-response breach rates near 55-60%, well above the smaller tail — and Studio Vrij/Marrowby & Vane also have the worst resolution times/breach rates among the top 10, despite having fewer agents than Cragsley. That's a concrete 'specific merchant driving disproportionate pain' candidate for Daniel, but I want the breach-code validation done before I state it as fact. With the other two slots I'm moving to priority #3 (what makes a ticket slow — channel and unassigned status, which both leaders asked about explicitly) and starting priority #4 (macro reliance), since night 4 is the last chance to cover KB effectiveness and CSAT.

    Macro usage overview
    Question
    How much do agents actually lean on canned-reply macros, and is usage concentrated in a few macros or spread across the library?
    One row per
    macro, restricted to the top 20 by usage_count
    Columns
    • macro_title
    • is_shared
    • usage_count

    • total_macro_usage_sum (constant: sum of usage_count across all macros)
    • total_agent_reply_messages_2025 (constant: count of ticket_messages with is_public = true and author_agent_id not null, created_at in 2025, as a rough denominator for how many agent replies exist platform-wide)

      Report request from Ben Carter (analyst for the Support Operations Manager):
      
      Title: Macro usage overview
      Question: How much do agents actually lean on canned-reply macros, and is usage concentrated in a few macros or spread across the library?
      Grain: one row per macro, restricted to the top 20 by usage_count
      Columns:
      - macro_title
      - is_shared
      - usage_count
      - pct_of_total_macro_usage (this macro's usage_count / sum of usage_count across all macros)
      - total_macro_count (constant: count of all non-deleted macros)
      - total_macro_usage_sum (constant: sum of usage_count across all macros)
      - total_agent_reply_messages_2025 (constant: count of ticket_messages with is_public = true and author_agent_id not null, created_at in 2025, as a rough denominator for how many agent replies exist platform-wide)
      Details: Source tables: macros (deleted_at is null), ticket_messages for the context denominator. macros.usage_count is a running lifetime counter (no date filter available on it), so note in the report that usage_count is all-time, not 2025-only, while total_agent_reply_messages_2025 is scoped to 2025 — the ratio is a rough reliance signal, not exact. Order by usage_count descending, top 20 rows; note the total number of macros in the library so we can see how many are barely used.
