Prerequisite

What needs to be finished first

Complete firstConcrete subject

Define research question, duration, and triggering event; plan privacy, support, and a short pilot.

Without a boundary the run becomes generic and untestable.
Complete firstAccess and participation

Research lead · participants · recorder or analyst · domain decision owner

Missing perspectives or access are made visible before starting.
02

Preparation

What needs to be ready before start

Materials

Consent, research protocol, secure raw-data store, and analysis surface

People / roles

Research lead · participants · recorder or analyst · domain decision owner

Pre-read

Define research question, duration, and triggering event; plan privacy, support, and a short pilot. Prepare real cases, sources, and boundaries.

Time needed

One to four weeks plus exit interviews.

Setup

Create a workspace with Study plan · Sample · Piloted template · Diary entries · Longitudinal patterns; keep example values separate from live data.

03

Core question

The one question this method answers

Which recurring experiences, triggers, and changes appear over time beyond a single session?

04

Flow

Phases with goal, actions, output and pitfall

A diary study captures moments close to participants’ lived experience, preserving context and time. Later analysis reveals patterns across duration, change, and repetition in everyday use.

  1. 1

    Design

    Study plan

    Goal

    Study plan: Define research focus, duration, event- or interval-based logging, and privacy.

    Inputs for this step

    • Define research question, duration, and triggering event; plan privacy, support, and a short pilot.
    • Consent, research protocol, secure raw-data store, and analysis surface

    Actions

    • Define research focus, duration, event- or interval-based logging, and privacy.

    Output

    Study plan

    Define research focus, duration, event- or interval-based logging, and privacy

    Quality check

    Are question, duration, event logic, and privacy explicit?

    Pitfall

    When duration and event logic stay unclear, participants later do not know when an entry is due. Fix the research focus, duration, entry triggers, and privacy rules clearly before the study starts.

    Timing: Use the time needed within the overall frame; close the step only after its check passes.

  2. 2

    Template

    Sample

    Goal

    Sample: Pilot a diary format with short prompts, timestamps, and optional media evidence.

    Inputs for this step

    • Study plan

    Actions

    • Pilot a diary format with short prompts, timestamps, and optional media evidence.

    Output

    Piloted template

    Pilot a diary format with short prompts, timestamps, and optional media evidence

    Quality check

    Is the template short, understandable in daily use, and piloted with real entries?

    Pitfall

    When the template uses long prompts or jargon, participants abandon entries in daily life. Pilot the format with short prompts and timestamps against real test entries and simplify it afterward.

    Timing: Use the time needed within the overall frame; close the step only after its check passes.

  3. 3

    Recruit

    Piloted template

    Goal

    Piloted template: Onboard participants, practise one entry, and explain the support path.

    Inputs for this step

    • Sample

    Actions

    • Select participants for relevant experience and usage contexts; confirm consent before the first entry.
    • Onboard participants, practise one entry, and explain the support path.

    Output

    Onboarded sample

    Onboard participants, practise one entry, and explain the support path

    Quality check

    Can participants create a complete entry and reach support?

    Pitfall

    When participants start without practice, it stays unclear whether they can create a complete entry or reach support when needed. Select participants deliberately by experience, practice one example entry together, and show the support channel.

    Timing: Use the time needed within the overall frame; close the step only after its check passes.

  4. 4

    Diary

    Diary entries

    Goal

    Diary entries: Collect entries over time, monitor completion, and send neutral reminders.

    Inputs for this step

    • Piloted template

    Actions

    • Collect entries over time, monitor completion, and send neutral reminders.

    Output

    Diary entries

    Collect entries over time, monitor completion, and send neutral reminders

    Quality check

    Do reminders remain neutral, with missing entries visible rather than filled in?

    Pitfall

    When reminders suggest the expected answer or missing entries get filled in afterward, the longitudinal data is distorted. Keep reminders neutral and leave missing entries visible as gaps instead of filling them in.

    Timing: Use the time needed within the overall frame; close the step only after its check passes.

  5. 5

    Analyse

    Longitudinal patterns

    Goal

    Longitudinal patterns: Analyse entries across time, triggers, and cases, then deepen findings in exit interviews.

    Inputs for this step

    • Diary entries

    Actions

    • Analyse entries across time, triggers, and cases, then deepen findings in exit interviews.

    Output

    Longitudinal patterns

    Analyse entries across time, triggers, and cases, then deepen findings in exit interviews

    Quality check

    Are longitudinal patterns supported by entries and checked in exit interviews?

    Pitfall

    When time patterns are asserted only from a gut feeling, they cannot be defended in the exit interview. Ground every pattern in concrete entries and verify it with participants during the exit interview.

    Timing: Use the time needed within the overall frame; close the step only after its check passes.
