Product architecture you will not have to rebuild.

We connect participants, decision points, business rules, data and system boundaries in a model the team can evaluate and implement.

Impact map

The cost of change is not determined by the feature itself. The number of decisions it affects.

01 · New user type

Needs review

  • Permissions
  • Data
  • Scenarios
  • Constraints
  • Interface
  • Analytics

If architecture there is no

A role is added to the existing structure, and contradictions appear during implementation.

If architecture is

The role and its accountability are defined before estimation.

Product architecture makes the consequences of decisions visible before they become changes in code and budget.

Solution

Add a new “Partner” role

The feature can be assessed separately. Its consequences cannot.

  1. 01ResponsibilitiesWhat the partner sees, changes and approves
  2. 02CatalogueWhich range and terms are available to them
  3. 03PriceWhat rule determines its price
  4. 04OrdersWho places the order, who approves and who pays
  5. 05DocumentsWhich documents are created and who signs them
  6. 06AnalyticsHow sales partners are separated from direct customers
  7. 07SupportWho is responsible for customer questions

One business decision changes seven parts of the product.

Architecture view

To design a screen, you need to know, which decisions happen behind it.

(01) Participants

Who interacts with the product and owns which result.

Without defined roles, the team designs for “the user in general” and adds roles on top of finished screens.

  • Roles
  • Accountability
  • Interests
  • Constraints roles

Role structure →
Accountability → Permissions

What this givesRoles are defined for design, and not for time development.

(02) Decision points

Where the user chooses, verifies, approves or hands over responsibility.

Without this, the interface shows data but does not help make a decision.

  • Choice
  • Verification
  • Confirmation
  • Handover of responsibility

Solution → required information →
Display moment

What this givesThe screen supports decisions, and not simply shows state.

(03) Scenarios

How participants move from actions to results.

Without a complete set of journeys, development estimates the happy path while you pay for exceptions.

  • Core
  • Alternative
  • Critical
  • Errors and rollbacks

byaction → Participant actions →
Result

What this givesThe assessment accounts for exceptions, not only the ideal case.

(04) Rules

Prices, limits, statuses, terms, exceptions and approvals.

Without a single source, a rule is duplicated in code, spreadsheets and agreements.

  • Prices
  • Limits
  • Statuses
  • Terms
  • Exceptions
  • Approvals

Rule → Source →
Impact on journeys

What this givesEach rule has one source and a predictable impact.

(05) Data

What information is needed for a decision, where it comes from and who may change it.

Without a data model, the team does not know which data to trust or where to fix an error.

  • Data composition
  • Sources
  • Permissions changes
  • Freshness
  • Accountability

Source → Permissions changes →
Accountability

What this givesIt is clear which data to trust and who their fixes.

(06) Boundaries

What is part of the product, what stays in external systems and where accountability passes.

Without defined boundaries, development scope grows during implementation.

  • Boundaries product
  • External systems
  • Integrations
  • Area of responsibility

Product → Integrations →
External systems

What this givesThe scope does not grow along the way: boundaries are agreed before estimation.

If even one level is not defined, the team compensates with assumptions for time design and development.

Architecture view product: roles, decisions, rules and data

Entry point

With which situations does architecture work begin?

Situation 01

The product is only being planned

We define roles, the core journey, rules, data and the first version.

Resultbasis for estimate to start development.

FormatArchitecture project

Situation 02

Requirements are already collected

We verify contradictions, dependencies, exceptions, hidden decisions and journey completeness.

ResultA technical challenge does not give the team conflicting requirements.

FormatAudit architecture

Situation 03

Development has already started

We find decisions the team makes locally, repeated logic and places that will require future rework.

ResultWe fix the most expensive dependencies before the next part of the product is built.

FormatAudit architecture

Situation 04

The product is difficult to grow

We define where exceptions have accumulated, why changes affect the whole system and what can be fixed locally.

ResultA change plan without automatic decisions rewriting the entire product.

FormatArchitecture session or audit

Personal accountability

Product architecture cannot be assembled from separate business-analytics and design decisions and developer.

  • Business analyst

    • describes requirements
    • records processes
    • maintains documentation

    Constraintscan record a requirement without deciding whether it should become part of the product.

  • UX designer

    • designs interactions
    • simplifies the journey
    • works with interface

    Constraintscan improve a journey without seeing all business rules and system dependencies.

  • Technical architect

    • chooses the implementation approach
    • assesses load
    • designs the system

    Constraintsanswers “how to build”, but not always “which product model to build”.

Sheker.Agency’s position

Natalia Sheker connects the business model, user behaviour, product rules and implementation logic in one decision.

What she does personally

Leads key sessions · checks contradictions · defines boundaries · makes first-version decisions · explains consequences to the client team.

You work not with an intermediary collecting specialists’ opinions, with the expert responsible for the integrity of the product decision.

How the work proceeds

Architecture is formed not through a series of presentations, and three decision cycles.

Every cycle ends with a decision you can see and approve. We do not hold interim findings until the final presentation.

Reality → Model → Handover

  1. 01

    Reconstruct reality

    • We work with the owner, product team and user processes.
    • We review available materials and current systems.
    • We document how the process works now
    • We identify where rules differ from procedures.
    • We document decisions that depend on specific people.
    • We identify where exceptions arise.

    ResultA realistic product model, not an idealised description of the process.

  2. 02

    Agree the model

    • We define roles and accountability
    • we describe key scenarios
    • we document rules, data and boundaries
    • We verify conflicts and the consequences of decisions.
    • We assess cost and complexity.

    ResultAgreed product logic before screen-level detail.

    Artefact · model roles, scenarios and rules

  3. 03

    Prepare for implementation

    • we document boundaries first version
    • We record architectural decisions and alternatives.
    • We list open questions and dependencies.
    • We formulate success criteria.
    • We prepare materials for the team.

    Resulta basis for estimation, UI/UX and technical architecture.

What remains in team

The team receives not just a system diagram, but and a decision set for the next stage..

Roles, interests and accountability.

Who sees, changes, approves and is responsible.

Where key decisions are made and what information they need.

Core, alternative and critical scenarios.

Terms, statuses, limits, exceptions and approvals.

What information exists, where it comes from and who manages it.

Which decisions affect other parts of the product.

What is included in the product, what remains in external systems and where accountability passes.

What scope is sufficient for launch or the next test.

What was chosen, which alternatives were considered and why they were rejected.

The basis for estimates, UI/UX, technical architecture and development.

Example architecture package: roles, rules and version boundaries

The result can be handed to the internal team or another contractor. Further development with Sheker.Agency is not required to use the architecture.

After the stage, the team understands not only what to build, and which decisions cannot be changed locally without consequences for the entire product.

Formats and cost

The work scope is determined not by the number of screens, and the number of related decisions.

Discuss architecture

{{Prices require approval by the Sheker.Agency owner before publication}}

Discuss the architecture

document decisions that now change several parts of the product.

In the first conversation, we discuss the product, roles, rules, data and complexity the team sees. We define whether an architecture session, audit or full design is enough.

If the problem is local and does not require a separate architecture stage, we will say so before work begins.







    We will send confirmation and a meeting link. No presentations – straight to your numbers.

    The first conversation is with an expert personally responsible for the product model and the consequences of key decisions.
