How the assignment works

How the assignment works

A short, explicit process adapted to the sensitivity of the situation.

  1. 01

    Scoping

    We define the decision to support, relevant assets, constraints, authorised sources and required confidentiality.

  2. 02

    Investigation

    Collection and analysis follow the agreed scope. Facts, hypotheses and areas of uncertainty remain clearly separated.

  3. 03

    Prioritisation

    Each finding is assessed by reliability, likely impact and the effort required to act.

  4. 04

    Delivery

    You receive a readable synthesis, useful evidence and a roadmap that can be put into practice.

Possible deliverables

Possible deliverables

  • UX, performance and security audit
  • Website architecture or redesign
  • Hardening, backups and monitoring
  • Maintenance and continuous improvement plan

Common situations

Common situations

  • An ageing site that is hard to evolve
  • Weak loading speed, conversion or accessibility
  • Need for a sober, secure web foundation

Before the assignment

Frame a useful decision

The review follows important website tasks and the conditions needed to operate them. It examines content, interface, accessibility, speed, security and maintainability together to prioritise fixes that improve the complete service.

Information to gather

  • Essential journeys and affected audiences
  • Available performance data and user feedback
  • Architecture, hosting and publishing cycle

Decisions to prepare

  • Improve the existing foundation or plan a rebuild?
  • Which components create repeated barriers?
  • How will recovery after an incident be validated?
  • Can a form, API or email actually finish and confirm the task?
  • Which permissions, variants or field metrics prevent a task from completing correctly?
  • Which difference would change the decision?
  • Which facets deserve discoverable pages?
  • Where does focus return if the trigger disappears?
  • Does higher retention prove a product effect?
  • How should the last unit be checked?
  • Is a global CSS rule sufficient?
  • Does DISTINCT fix an incorrect join?
  • Can a refund be announced when a return is approved?
  • Does navigator.onLine establish service access?
  • Is HTTP 429 sufficient protection?
  • Should every table become cards?
  • Does a faster site always emit less?
  • Can an import reactivate a subscriber?
  • Does an empty page mean completion?
  • Should every update be announced?
  • Do all currencies use two decimals?
  • Is a valid extension enough?
  • Should sizes always be 100vw?
  • What starting percentage should be used?
  • Should missing values become zero?
  • Does cancellation mean a refund?
  • Does 202 mean the job is finished?
  • Does Intl.NumberFormat parse input?

Illustrative assignment

Situation
A request form works on desktop but loses information and poorly confirms submission on mobile.
Work
Test the complete journey with keyboard, zoom and slow network; compare technical errors, messages people see and measurement events.
Deliverable
A prioritised fix list, observable acceptance criteria and a regression check after release.

Example acceptance criteria to agree during scoping

  • The essential task completes on mobile, with keyboard and after an error.
  • An unavailable dependency does not leave misleading state.
  • Removed scripts do not return through downstream loading.

FAQ

Frequently asked questions

Practical answers to help frame the need before an initial conversation.

Does the audit cover UX, performance and security together?

Yes. These dimensions are assessed together because a fast but confusing journey, or a clear but vulnerable one, does not create a durable web service.

Can you work on an existing website?

Yes. The assignment can begin with a focused audit, address priorities, prepare a redesign or establish ongoing maintenance according to the condition of the existing foundation.
