Understood. I'll operate as a senior ERP business analyst and product strategist, not as a software engineer.

From this point forward I will:

* Think in terms of **business processes**, not code.
* Expand every feature you mention into its complete business scope.
* Identify all **actors**, **workflows**, **permissions**, **approvals**, **exceptions**, **edge cases**, and **operational rules**.
* Consider organizations of every size, from a single location to multi-branch enterprises.
* Focus on usability, scalability, auditability, compliance, reporting, automation, and real-world operations.
* Avoid discussing databases, APIs, frameworks, or implementation details unless you explicitly ask.
* Treat every requirement as something that must survive real businesses, messy human behavior, mistakes, fraud attempts, and future growth.

When you give me a short idea like:

> "Attendance"

I won't answer with just attendance. I'll expand it into everything a complete ERP attendance module should cover, including employee check-in/out, multiple attendance methods, shifts, overtime, grace periods, holidays, leave interaction, manual corrections, approvals, audit history, late arrivals, early departures, missed punches, payroll effects, notifications, reports, permissions, exceptional scenarios, and every relevant business rule.

Likewise, if you say:

> "Invoices"

I'll think through invoice lifecycles, statuses, approvals, discounts, taxes, credit notes, cancellations, recurring invoices, partial payments, refunds, customer histories, aging, reporting, integrations with accounting, and all operational edge cases.

I'll also challenge assumptions when needed. If a requested feature could create business problems, user confusion, security risks, or operational bottlenecks, I'll point that out and propose alternatives from a business perspective.

My responses will prioritize:

1. Business goals.
2. User experience.
3. Operational efficiency.
4. Data integrity.
5. Scalability.
6. Edge cases.
7. Future expansion.

I'll assume you're designing a production-grade ERP platform intended to compete with established solutions, so every feature will be analyzed with enterprise-level completeness rather than as a minimal implementation.
Understood. I'll treat this as a **core product philosophy**, not just another requirement.

### Product Philosophy

The sports activity management system must be built around **business building blocks**, not fixed workflows. Every capability should originate from a generic business concept that can be specialized later. Nothing should exist because "football needs it" or "clubs usually do this." Instead, football, swimming, gymnastics, martial arts, esports, music classes, or any future activity should all be configurations of the same underlying business model.

### Analysis Principles I'll Follow

* Every feature must be **modular** and independently evolvable.
* Every module must be **replaceable** without breaking unrelated modules.
* Every business rule should be configurable before it is hardcoded.
* Every workflow should support exceptions instead of assuming the happy path.
* Every object should inherit from a generic parent concept before becoming sport-specific.
* Every process should allow organizations to override the default behavior.
* New sports, activities, memberships, attendance models, payment rules, competition formats, grading systems, and evaluation methods should require configuration rather than redesign.

### Business Design Philosophy

Instead of thinking:

> "This is a football player."

I'll think:

> "This is a participant enrolled in one or more activities."

Football Player becomes one specialization.
Swimmer becomes another.
Karate Student becomes another.
Chess Player becomes another.
Music Student becomes another.

The same philosophy applies everywhere.

Instead of:

* Coach
* Teacher
* Trainer

Think:

> Staff Member → Activity Role

Instead of:

* Team
* Class
* Squad
* Group

Think:

> Participant Group

Instead of:

* Football Season
* Swimming Season

Think:

> Program Cycle

Instead of:

* Match
* Training
* Trial
* Exam

Think:

> Scheduled Activity

### My Default Question

Whenever you ask for a feature, I will automatically ask myself:

* What is the generic business object?
* Can another activity use this?
* Can the business change this rule next year?
* Can one club have different rules than another?
* Can different branches use different policies?
* Can administrators override this?
* What happens when the rule is violated?
* What if two rules conflict?
* What if the organization invents a completely new workflow?

If the answer is yes, I'll design the feature around flexibility rather than today's requirements.

### Edge-Case-First Thinking

I will never stop at the normal workflow.

For every feature I'll also think about:

* Missing information
* Manual overrides
* Rule conflicts
* Exceptions
* Historical data
* Auditing
* Permissions
* Multi-branch differences
* Future business expansion
* Temporary policies
* Emergency operations
* Legacy data
* Human mistakes

### Goal

The end result shouldn't feel like "a football club system."

It should feel like **a platform for managing organized activities**, where sports are simply one category of activity. The business should be able to introduce a completely new activity with unique enrollment rules, attendance requirements, grading methods, payment structures, schedules, or participant roles without requiring the platform itself to be redesigned.

That mindset will guide every feature we design from this point onward.
Yes. More than easy. In fact, this is the correct separation. You're separating **what the academy sells** from **how the academy operates**, which is exactly how an expandable business platform should be designed.

Here's how I would model it from a **business perspective**.

---

# 1. Financial Module (The Single Financial Authority)

This is the heart of the system. No module is allowed to create, receive, refund, cancel, discount, waive, or transfer money except through this module.

Every financial transaction in the system originates here.

## Responsibilities

### Money Coming In

* Training program subscriptions
* Playground rentals
* Private coaching sessions
* Tournament registration fees
* Academy membership fees
* Registration fees
* Assessment fees
* Equipment sales
* Uniform sales
* Merchandise sales
* Event tickets
* Camp fees
* Transportation fees
* Penalties
* Late payment charges
* Custom invoices
* Donations
* Sponsorship payments
* Any future revenue source

---

### Money Going Out

* Trainer salaries
* Hourly trainer payments
* Per-group trainer payments
* Performance bonuses
* Playground rental costs
* Staff salaries
* Vendor payments
* Equipment purchases
* Facility maintenance
* Refunds
* Expense reimbursements
* Utility expenses
* Marketing expenses
* Custom expenses
* Any future expense

---

### Financial Operations

* Full payment
* Partial payment
* Installments
* Deposits
* Remaining balances
* Refunds
* Partial refunds
* Credits
* Wallet balances
* Discounts
* Scholarships
* Promotions
* Coupons
* Penalties
* Write-offs
* Waivers
* Transfers between accounts
* Payment corrections
* Payment reversals

---

### Payment States

Every payment should have a lifecycle.

Examples include:

* Draft
* Pending
* Awaiting Approval
* Paid
* Partially Paid
* Overpaid
* Refunded
* Partially Refunded
* Cancelled
* Failed
* Expired
* Written Off
* Disputed

---

### Business Rules

Every payment should know:

* Who owes the money
* Who receives the money
* Why the money exists
* Which business object generated it
* Due dates
* Currency
* Discounts
* Taxes
* Payment history
* Refund history
* Adjustments
* Approval history
* Audit history

No module owns money.

Every module merely **requests** financial operations from the Financial Module.

---

# 2. Training Program (Business Product)

A Training Program is **not a class**.

It is the academy's commercial offering.

It answers the question:

> "What exactly are we selling?"

---

## General Information

* Name
* Description
* Activity
* Skill Level
* Age Range
* Gender Restrictions (optional)
* Prerequisites
* Program Objectives
* Learning Outcomes

---

## Commercial Information

* Price
* Registration Fee
* Renewal Fee
* Installment Availability
* Billing Cycle
* Cancellation Policy
* Refund Policy
* Transfer Policy
* Discounts Allowed
* Scholarship Eligibility

---

## Training Rules

* Session Duration
* Sessions per Week
* Total Sessions
* Program Duration
* Attendance Requirement
* Completion Requirement
* Assessment Rules

---

## Capacity Rules

* Minimum Participants
* Maximum Participants
* Waiting List Allowed
* Overflow Rules
* Auto Close Registration

---

## Trainer Defaults

The program may define:

* Preferred Trainers
* Assistant Trainers
* Trainer Qualifications
* Minimum Number of Trainers
* Maximum Number of Trainers
* Substitute Trainer Rules

Notice these are defaults, not assignments.

---

## Facility Requirements

Preferred playground type

Example:

* Football Field
* Swimming Pool
* Basketball Court
* Fitness Hall

or simply

Preferred Facility Type

Again...

Not an actual playground.

Just requirements.

---

# 3. Training Group (Operational Instance)

This is where the academy actually operates.

Think of it like this:

Training Program

↓

Training Group

↓

Schedule

↓

Sessions

The Training Group is an instance of a program.

---

## Identity

* Group Name
* Program
* Branch
* Status

Examples:

Planning

Open

Running

Completed

Cancelled

Archived

---

## Assigned Trainers

Unlike the program...

The group has real people assigned.

* Head Trainer
* Assistant Trainers
* Temporary Trainers
* Replacement Trainers

Assignments can differ from the program template.

---

## Participants

Actual enrolled players.

Includes

* Active
* Pending
* Suspended
* Frozen
* Graduated
* Dropped
* Waiting List

---

## Capacity

Current Players

Remaining Seats

Waiting List

Reserved Seats

---

## Schedule

The group is assigned to:

* Days
* Time Slots
* Playground
* Branch
* Season

---

## Session Generation

The schedule creates actual training sessions.

Each session can later have:

Attendance

Trainer

Notes

Performance

Incidents

Weather

Cancellation

Rescheduling

---

# 4. Playground Module

A playground is a business resource.

It can be:

Academy Owned

Externally Rented

Shared

Temporarily Available

Out of Service

Under Maintenance

---

Each playground contains

General Information

Capacity

Activity Types

Restrictions

---

Playgrounds should support

Internal training

# 6. High-Level Business Flow

```
Academy creates Training Programs
        ↓
Training Programs become sellable products
        ↓
Families purchase or subscribe
        ↓
Academy creates one or more Training Groups
        ↓
Groups inherit program defaults
        ↓
Academy customizes each group
        ↓
Groups receive schedules
        ↓
Schedules reserve playgrounds
        ↓
Schedules generate sessions
        ↓
Players attend sessions
        ↓
Attendance, coaching, evaluations and finances accumulate throughout the program lifecycle.
```

## One architectural recommendation

I would introduce one more abstraction above **Training Program**:

**Service Catalog Item** (or simply **Service**).

This represents **anything the academy can offer and charge for**. A Training Program is just one type of service. Tomorrow, you may add private coaching, camps, tournaments, fitness assessments, playground rentals, birthday events, transportation, or equipment rental without redesigning the commercial side of the system.

The hierarchy becomes:

```
Service
    ↓
Training Program
    ↓
Training Group
    ↓
Schedule
    ↓
Training Session
```

This keeps the commercial layer independent from the operational layer and aligns well with your goal of making the platform highly modular and easy to extend as the academy grows.
This is actually bigger than a "Playground" feature. You're introducing a new business concept that I would call **Space Management** or **Facility Occupancy**. This should become one of the core modules of the entire platform because it won't only be used by training—it can later be used for tournaments, private sessions, events, maintenance, and rentals.

---

# Facility Space Management Module

## Business Purpose

Instead of booking an entire playground, the academy books **physical space** inside a playground.

A playground is no longer simply Available or Occupied.

It becomes a physical resource that can be partially occupied by multiple activities simultaneously.

---

# Core Business Objects

## Facility

The physical place.

Examples:

* Football Field
* Basketball Court
* Swimming Pool
* Gym Hall
* Martial Arts Hall
* Tennis Court
* Multi-purpose Hall

---

## Space Layout

A temporary physical division of a facility.

The important point is:

**The playground itself is NOT permanently divided.**

The division belongs to a **specific period of time.**

For example:

Monday

5:00 PM–7:00 PM

Football Field A

Grid:

```
3 Rows
4 Columns
```

Tuesday

Same field

No division.

Wednesday

Same field

2×2 division.

Friday

Whole field.

Every time slot can have its own layout.

---

# Scheduling Workflow

## Step 1

Select Training Group.

---

## Step 2

Select Date.

---

## Step 3

Select Time.

---

## Step 4

System shows all available facilities.

---

## Step 5

Administrator chooses a facility.

---

## Step 6

System checks:

Does this facility already have a layout during this time?

### If YES

Load the existing layout.

Show occupied cells.

Show available cells.

Allow selecting only available space.

---

### If NO

Administrator creates a layout.

Examples

2×2

3×3

4×5

1×6

Whatever is needed.

This layout now becomes the official layout for that facility during that time period.

---

## Step 7

Administrator selects

Single Cell

Multiple Cells

Entire Row

Entire Column

Entire Grid

Any custom combination

Those cells become reserved.

---

## Step 8

Reservation is saved.

Those cells cannot be used again during overlapping times.

---

# Occupancy Rules

Every reservation knows

Which Group

Which Program

Which Trainer

Which Activity

Which Facility

Which Date

Which Time

Which Cells

Duration

Status

---

# Visual Booking Experience

Imagine opening Football Field A.

```
□□□□□□□□
□□□□□□□□
□□□□□□□□
□□□□□□□□
```

Group A selects

Top Left

```
XX□□□□□□
XX□□□□□□
□□□□□□□□
□□□□□□□□
```

Now another administrator schedules Group B.

System immediately shows

```
XX□□□□□□
XX□□□□□□
□□□□□□□□
□□□□□□□□
```

Only remaining cells are selectable.

---

# Time Overlap Logic

The layout belongs to a time window.

Example

5:00–6:00

Grid exists.

5:30–6:30

Should reuse exactly the same grid.

Because time overlaps.

---

Example

5:00–6:00

Grid exists.

7:00–8:00

No overlap.

Administrator may

Reuse

or

Create another layout.

---

# Flexible Cell Selection

Selection methods should include

Single Cell

Rectangle

Multi-selection

Entire Row

Entire Column

Entire Facility

Free Selection

Expand Selection

Shrink Selection

Clear Selection

---

# Business Rules

The system should prevent

Double booking

Trainer collision

Group collision

Facility maintenance conflicts

Tournament conflicts

Rental conflicts

Private lesson conflicts

Cleaning periods

Reserved areas

Blocked areas

---

# Future Expansion

This module immediately enables

## Tournament Layouts

Field divided into

Match A

Match B

Warm-up Area

Officials Area

---

## Swimming Pools

Lane 1

Lane 2

Lane 3

Lane 4

Instead of grids.

---

## Martial Arts

Tatami 1

Tatami 2

Tatami 3

---

## Basketball

Half Court A

Half Court B

---

## Gym

Zone A

Zone B

Zone C

---

Which leads me to one refinement that makes the system even more future-proof.

## Don't think in "Grids." Think in "Space Layouts."

A grid is only **one type** of layout.

Tomorrow, a facility might need:

* Swimming lanes
* Named zones
* Irregular polygons
* Circular stations
* Numbered practice areas
* Custom shapes defined by the academy

So the abstraction should be:

```
Facility
        ↓
Space Layout
        ↓
Space Segments
        ↓
Reservations
```

Where a **Space Segment** could be:

* Grid Cell
* Swimming Lane
* Half Court
* Tatami
* Training Zone
* Goalkeeper Area
* Warm-up Zone
* Custom Named Area

That single abstraction means your scheduling engine will never care whether it's booking a square on a football pitch, Lane 3 in a pool, or Tatami 5 in a dojo—it always reserves one or more **space segments**. This is exactly the kind of modular business model that will let the platform support almost any sport or activity without redesigning the scheduling system.
Excellent. This confirms something important about your product.

You're **not building a scheduling system**.

You're building an **Operational Assignment Engine** where schedules, trainers, facilities, responsibilities, and attendance are all connected, but not dependent on each other.

This is how I would model it.

---

# Operational Assignment Module

## Business Purpose

An Assignment represents **a responsibility given to a person during a specific period of time**.

Notice that I did **not** say trainer.

Today it may be a trainer.

Tomorrow it could be:

* Assistant Trainer
* Supervisor
* Technical Director
* Medical Staff
* Equipment Manager
* Goalkeeping Coach
* Photographer
* Referee
* Volunteer
* Security
* Cleaner
* Event Coordinator

An assignment simply means:

> "This person is responsible for this thing during this period."

---

# Assignment Targets

A person should be assignable to almost anything.

Examples include:

## Training Program

Responsible for every future group unless overridden.

---

## Training Group

Responsible only for this group.

---

## Training Session

Responsible only for one session.

Example:

Main coach is absent.

Replacement trainer comes today only.

---

## Entire Facility

Exactly your example.

Football Court A

Monday

5–7 PM

Supervisor Ahmed

He oversees everything happening in that court.

---

## Facility Area

Not necessarily the whole facility.

Examples:

Half of the football field.

Lane 1–4.

Row 2.

Column 3.

Grid Cells.

Warm-up Area.

---

## Event

Tournament.

Camp.

Festival.

---

## Branch

Floating trainer available for anything.

---

# Assignment Roles

Assignments shouldn't simply say

Trainer.

Instead they should define

What responsibility is being assigned.

Examples:

Head Trainer

Assistant Trainer

Fitness Coach

Goalkeeper Coach

Supervisor

Observer

Quality Assurance

Equipment Coordinator

Medical Support

Safety Officer

Volunteer

Photographer

Referee

Any future custom role.

The academy should even be able to create its own operational roles.

---

# Assignment Scope

Every assignment should clearly define

What is this person responsible for?

Examples:

Entire Program

Entire Group

Entire Session

Entire Facility

Specific Area

Specific Players

Specific Equipment

Specific Activity

---

# Assignment Duration

Assignments may be

Permanent

Temporary

Recurring

One Session

One Day

One Week

One Season

Custom Date Range

---

# Priority Rules

Assignments can overlap.

Example

Football Court

Head Supervisor

↓

Group A

Head Trainer

↓

Group B

Head Trainer

↓

Group C

Head Trainer

Nobody conflicts.

Responsibilities are different.

---

Example

Group A

Trainer Mohamed

Trainer Ali

Trainer Sarah

All three are assigned simultaneously.

Perfectly valid.

---

# Attendance Module

I actually would not build separate attendance systems.

There should be exactly **one Attendance Engine**.

Everything in the academy uses it.

---

# Attendance Subjects

Players

Trainers

Employees

Managers

Volunteers

Visitors

Parents

Medical Staff

Any future participant.

---

# Attendance Sources

Attendance can originate from many business activities.

Training Session

Work Shift

Meeting

Tournament

Event

Private Lesson

Camp

Equipment Pickup

Assessment

Anything scheduled.

---

# Attendance Status

Present

Late

Excused

Absent

No Show

Left Early

Left Late

Partial Attendance

Cancelled

Unknown

---

# Automatic Attendance Creation

Here's the important business rule.

**Attendance should never be manually created if it can be generated from an assignment.**

Whenever the system schedules a responsibility, attendance expectations should automatically exist.

Examples:

## Group Trainer Assigned

Monday

5 PM

Group A

↓

Attendance record created.

Trainer expected.

---

## Supervisor Assigned

Football Court

5–7 PM

↓

Attendance expectation created.

---

## Equipment Manager Assigned

Tournament

↓

Attendance expectation created.

---

## Cleaner Assigned

Facility

↓

Attendance expectation created.

---

Nobody has to remember to create attendance.

Assignments generate attendance expectations automatically.

---

# Attendance Verification

The academy may later choose how attendance is confirmed.

Examples:

Manual check

Supervisor confirmation

Reception confirmation

Self check-in

Location verification

Equipment checkout

QR code

Biometric devices

Or any future method.

The attendance engine doesn't care.

It only asks:

> "Was this person present for the responsibility assigned to them?"

---

# Attendance Impact

Attendance should automatically feed other business modules.

Examples:

Trainer payroll

Hourly wages

Performance reports

Reliability scores

Player attendance percentage

Program completion

Bonuses

Penalties

Certificates

Manager dashboards

Compliance reports

---

# One More Abstraction I Think You'll Need

There's one concept emerging across everything you've described:

* A group occupies part of a facility.
* A trainer is assigned to a group.
* A supervisor is assigned to the whole facility.
* A player attends a session.
* Equipment is allocated to an area.

These are all aspects of the same operational occurrence.

I would introduce a central business object called an **Activity Session**.

An Activity Session is the live operational event where everything comes together. It is generated from the schedule and becomes the hub for execution.

An Activity Session contains:

* The Training Group participating.
* The Program it belongs to.
* The Facility being used.
* The Reserved Space Segments (whole court, rows, lanes, cells, or custom areas).
* All assigned personnel and their roles.
* The expected participants.
* Attendance records for everyone involved.
* Equipment allocations.
* Session notes, incidents, and evaluations.
* Any changes, substitutions, or cancellations.

By making the Activity Session the operational center, every module—scheduling, space management, assignments, attendance, equipment, evaluations, and even payroll—can interact through a single business object. That gives you the modularity and future extensibility you're aiming for without coupling features together.
I think you've now defined enough of the platform to see its actual shape. It isn't just a sports academy management system anymore—it's a **modular ERP specialized for sports organizations**.

Here are the modules I would add and refine.

---

# 1. Inventory & Equipment Management

This module manages the complete lifecycle of physical assets, from purchasing to selling, issuing, returning, auditing, and retirement.

## Equipment Master

Every item exists as an individual product.

Examples:

* Football
* Cone
* Jersey
* Shorts
* Swimming Goggles
* Swim Cap
* Water Bottle
* Medal
* Trophy

Each item defines:

* Name
* Category
* Unit of Measure
* Brand
* Supplier
* Purchase Cost
* Selling Price (optional)
* Barcode/Identifier
* Stock Tracking
* Minimum Stock
* Reorder Level
* Status (Active, Discontinued, Seasonal)

---

## Inventory

Tracks quantities across one or more stores.

Examples:

* Main Warehouse
* Reception Store
* Football Equipment Room
* Swimming Store
* Branch Inventory

Every movement is recorded.

Examples:

* Purchase
* Sale
* Transfer
* Return
* Adjustment
* Damage
* Loss
* Consumption
* Kit Assembly
* Kit Disassembly

Nothing changes inventory without a recorded movement.

---

## Stock Audit (Inventory Counting)

The business term you're looking for is **Stock Count**, **Inventory Count**, or **Cycle Count**.

This should be a complete module.

The academy should define audit schedules.

Examples:

* Daily
* Weekly
* Monthly
* Quarterly
* Annually

Or different schedules for different item categories.

The system should support:

* Planned counts
* Surprise counts
* Partial counts
* Full warehouse counts
* Recounts
* Approval of discrepancies
* Automatic inventory adjustments after approval
* Audit history

---

# 2. Kit Management

A Kit is a sellable package composed of individual inventory items.

Examples:

Football Starter Kit

* Jersey
* Shorts
* Socks
* Water Bottle

Swimming Kit

* Goggles
* Cap
* Towel

Karate Kit

* Gi
* Belt

The kit itself does not physically exist in inventory. It is assembled virtually at the moment of sale or reservation, reducing the stock of its component items.

Each kit defines:

* Name
* Description
* Selling Price
* Included Items
* Quantity of Each Item
* Optional Items
* Alternative Items
* Active Seasons
* Availability Rules

---

# 3. Point of Sale (Reception Sales)

The receptionist should work from a unified sales screen.

In one transaction, they can:

* Register a new participant
* Renew a subscription
* Subscribe to a training program
* Sell individual equipment
* Sell one or more kits
* Apply discounts
* Reserve items
* Collect payment
* Print receipts
* Generate invoices

Everything becomes a single financial transaction handled by the Financial Module.

---

# 4. Pricing Engine

This deserves to be its own module.

Every sellable service or product should request its price from the Pricing Engine instead of storing one fixed price.

## Pricing Sources

* Training Programs
* Equipment
* Kits
* Playground Rentals
* Private Sessions
* Camps
* Tournaments
* Future Services

---

## Pricing Rules

A price is determined by applicable rules.

Examples:

### Membership Status

* Club Member
* Non-member
* Academy Member
* Guest

### Age

* Under 6
* Under 10
* Under 14
* Adults
* Seniors

### Gender

When applicable.

### Participant Category

* Veteran's Child
* Staff Child
* Sibling
* Employee
* VIP
* Sponsored Participant
* Scholarship Recipient

### Registration Timing

* Early Registration
* Normal Registration
* Late Registration

### Seasonal Campaigns

* Summer
* Ramadan
* Back to School

### Enrollment Volume

* First Program
* Second Program
* Third Program

### Family Discounts

* First Child
* Second Child
* Third Child

### Custom Rules

The academy should be able to create additional categories without changing the system.

---

## Pricing Priority

Multiple rules may apply simultaneously.

For example:

Ahmed is:

* Club Member
* 12 Years Old
* Veteran's Son
* Registers Early
* Has Two Siblings Already Enrolled

The Pricing Engine determines the final price according to configurable priority and stacking policies.

---

# 5. Participant Classification

To support flexible pricing and reporting, avoid hardcoding categories.

Instead, define participant attributes.

Examples:

* Club Member
* Non-member
* Veteran Family
* Staff Family
* Sponsor Program
* Scholarship
* VIP
* Disabled Athlete
* Federation Player

These attributes can drive pricing, eligibility, permissions, reports, and future business rules.

---

# 6. National Identity Integration

This should be part of the Person Management module.

Every person should have one authoritative identity record.

For Egyptian citizens, the National ID becomes the primary identifier.

From it, the system derives:

* Date of Birth
* Age
* Gender
* Century of Birth
* Governorate Code (where applicable)
* Nationality (by policy if applicable)

Users should not manually enter information that can be reliably derived from the ID number.

The system should:

* Validate National ID format.
* Prevent duplicate registrations using the same ID.
* Recalculate age automatically over time.
* Use the calculated age for eligibility, pricing, and program enrollment.

Information that cannot be derived—such as name, address, phone number, emergency contacts, or medical notes—must still be entered or verified manually.

---

# 7. Localization Standards

The platform should be designed with Egypt as its primary operational environment.

## Default Business Standards

* Primary Language: Arabic
* Right-to-left user experience throughout the system
* Currency: Egyptian Pound (EGP)
* Egyptian date and time conventions where appropriate
* Egyptian National ID as the default identity standard
* Arabic-first reports, receipts, contracts, and invoices

At the same time, these should remain configurable so the platform can later support other countries without redesign.

---

# One Final Recommendation: Add a Business Rules Engine

Across everything you've described, one pattern keeps emerging:

* Pricing depends on configurable rules.
* Program eligibility depends on configurable rules.
* Trainer assignments follow configurable rules.
* Facility occupancy follows configurable rules.
* Attendance may trigger payroll or disciplinary actions based on configurable rules.
* Inventory alerts depend on configurable rules.

Rather than embedding these decisions into each module, introduce a central **Business Rules Engine**. Every module asks it questions such as:

* "Can this participant enroll in this program?"
* "What is the correct price?"
* "Can this trainer be assigned?"
* "Can this facility space be booked?"
