  • Employee stores HR profile information and references the user account where applicable.
  • The employee-to-employee relationship supports reporting hierarchy.
  • Payroll, performance, and recruitment modules are modular but share employee and company references.
  • Audit and notification tables should be designed as cross-module shared services.

13. Business rules

  • An employee may only have one active primary manager at a time.
  • An attendance record must belong to one employee and one work date.
  • A leave request cannot be approved if policy balance validation fails, unless override permission exists.
  • Payroll cannot be finalized twice for the same employee and payroll period.
  • Employees can edit only approved self-service profile fields.
  • Managers can approve requests only for employees within their reporting scope.
  • Terminated employees must be restricted from active login based on policy.

14. Non-functional requirements

Performance

  • Common dashboard pages should load quickly under normal usage.
  • Attendance actions should complete with minimal delay.
  • Search and filter actions should remain responsive for large employee directories.

Scalability

  • The architecture should support modular horizontal scaling of attendance, payroll, and notification services.
  • The platform should support growth from a single branch to multi-branch organizations.

Security

  • All traffic shall use encrypted transport.
  • Sensitive employee and payroll data shall be protected at rest.
  • Role-based access control shall be enforced server-side.
  • Audit logs shall capture critical administrative and payroll actions.

Availability

  • The system should be designed with backup and recovery procedures.
  • Critical data changes should be protected from accidental loss.

Usability

  • The interface should use clear status indicators for approvals and exceptions.
  • The system should support accessible forms and readable navigation.
  • Mobile primary tasks should be streamlined for one-hand use.

Localization

  • The platform should support configurable timezone and regional date formatting.
  • The platform should be designed to support future multilingual interfaces.

15. Recommended technology stack

নিচের নথিটি Development Kickoff-এর ভিত্তি হিসেবে ব্যবহার করা যাবে। এতে প্রথমে build-blocking gap, তারপর recommended technical decisions, architecture, sprint plan, testing এবং release criteria দেওয়া হয়েছে।

:::writing{variant="document" id="48317"}

HRMS Requirements Review, Gap Analysis এবং Developer-ready Implementation Plan

ডকুমেন্ট সংস্করণ: 1.0
প্রযোজ্য পরিধি: HRMS Web App, Mobile App এবং Backend Platform
প্রধান লক্ষ্য: Development শুরুর আগে অস্পষ্টতা, business-rule gap, security risk এবং architecture risk শনাক্ত করা এবং একটি বাস্তবায়নযোগ্য delivery plan নির্ধারণ করা।


Part A: Requirements Review and Gap Analysis

1. Executive assessment

বর্তমান SRS একটি শক্তিশালী product foundation তৈরি করেছে। এতে প্রয়োজনীয় module, user role, screen flow, core entity, high-level API, backlog এবং release plan অন্তর্ভুক্ত আছে।

তবে এটি এখনো সরাসরি coding শুরু করার মতো সম্পূর্ণ developer-ready নয়। প্রধান ঘাটতিগুলো হলো:

  1. MVP scope-এর কিছু অংশ পরস্পরবিরোধী।
  2. Multi-company বা tenant isolation স্পষ্টভাবে সংজ্ঞায়িত নয়।
  3. Role এবং permission model যথেষ্ট granular নয়।
  4. Attendance ও leave calculation-এর গুরুত্বপূর্ণ business rule অনুপস্থিত।
  5. Approval workflow-এর state এবং escalation rule নির্ধারিত নয়।
  6. বর্তমান ER model কিছু গুরুত্বপূর্ণ relationship সঠিকভাবে উপস্থাপন করছে না।
  7. API specification এখনো পূর্ণ contract নয়।
  8. Security, availability এবং performance requirements পরিমাপযোগ্য নয়।
  9. Mobile GPS attendance-এর privacy এবং fraud-control requirement অসম্পূর্ণ।
  10. Testing, deployment, migration এবং production monitoring-এর acceptance criteria নেই।

সামগ্রিক সিদ্ধান্ত

Development শুরু করা যাবে, তবে প্রথমে একটি Sprint 0 বা Foundation Sprint সম্পন্ন করা প্রয়োজন। এই sprint-এ scope, data model, permission matrix, workflow state এবং technical architecture lock করতে হবে।


2. Priority classification

Priorityঅর্থDevelopment impact

P3 — LaterPhase 2 বা future enhancementMVP development বন্ধ করবে না

3. P0 build-blocking gaps

GAP-01: MVP scope-এ পরস্পরবিরোধিতা

SRS-এর এক অংশে recruitment, onboarding, payroll এবং performance management-কে Phase 2 বলা হয়েছে। আবার required web sections-এ এগুলোকে আবশ্যিক screen হিসেবে দেখানো হয়েছে।

Employee self-service-এর মধ্যে payslip access রয়েছে, কিন্তু payroll MVP-এর বাইরে। একইভাবে reports export এক জায়গায় MVP scope-এর অংশ, অন্য জায়গায় future iteration বলা হয়েছে।

ঝুঁকি

  • UI team এবং backend team ভিন্ন scope ধরে কাজ করতে পারে।
  • MVP estimate এবং delivery date ভুল হতে পারে।
  • অসম্পূর্ণ menu বা dead-end screen তৈরি হতে পারে।

Recommended decision

MVP-তে শুধুমাত্র নিচের module সক্রিয় থাকবে:

  • Authentication এবং access control
  • Organization setup
  • Employee management
  • Attendance
  • Attendance correction
  • Leave management
  • Employee self-service
  • Notifications
  • Announcements
  • Basic reports
  • Documents-এর সীমিত read/upload capability
  • Web এবং mobile core workflows

নিচের module-এর menu, API এবং database functionality Phase 2 feature flag-এর পেছনে থাকবে:

  • Recruitment
  • Onboarding
  • Payroll
  • Performance management
  • Asset management

Payslip screen MVP-তে প্রদর্শিত হবে না, যদি না external payroll system থেকে payslip upload করার একটি স্পষ্ট requirement যোগ করা হয়।

Report export-এর ক্ষেত্রে MVP baseline হবে:

  • CSV/XLSX export: MVP
  • PDF export: optional বা Phase 1.1

GAP-02: Tenant বা company isolation model অনির্ধারিত

SRS-এ Company entity আছে, কিন্তু system single-company deployment হবে নাকি SaaS multi-tenant platform হবে তা বলা হয়নি।

ঝুঁকি

এক organization-এর employee, attendance বা payroll data অন্য organization-এর user-এর কাছে প্রকাশিত হওয়ার সম্ভাবনা তৈরি হবে।

Recommended decision

Platform-কে শুরু থেকেই multi-tenant capable হিসেবে design করতে হবে, এমনকি প্রথম deployment-এ একটি company থাকলেও।

প্রত্যেক business table-এ সরাসরি বা নির্ভরযোগ্য relational path-এর মাধ্যমে company_id থাকতে হবে।

প্রয়োজনীয় নিয়ম:

  • Company context authenticated token থেকে নির্ধারিত হবে।
  • Client request থেকে পাঠানো companyId বিশ্বাস করা যাবে না।
  • প্রতিটি query server-side tenant scope প্রয়োগ করবে।
  • Super Admin-এর cross-company access আলাদা privileged permission হবে।
  • Unique constraint company scope অনুযায়ী হবে।

উদাহরণ:

text
UNIQUE(company_id, employee_code) UNIQUE(company_id, email) UNIQUE(company_id, department_name)

GAP-03: Role এবং permission model অপর্যাপ্ত

বর্তমান Role.permission_set string-based field production-grade RBAC-এর জন্য যথেষ্ট নয়।

Manager কোন employee দেখতে পারবেন, branch admin কোন branch পরিচালনা করবেন এবং payroll user কোন salary data দেখতে পারবেন—এগুলোর data scope নির্ধারিত হয়নি।

Recommended model

নিচের entity প্রয়োজন:

  • roles
  • permissions
  • role_permissions
  • user_role_assignments
  • role_scope_assignments

Permission format হতে পারে:

text
employee.read employee.create employee.update attendance.read.team attendance.correct leave.approve leave.override document.read.salary payroll.finalize settings.manage audit.read

Permission-এর সঙ্গে scope যুক্ত থাকতে হবে:

  • Own
  • Direct reports
  • Reporting hierarchy
  • Department
  • Branch
  • Company
  • Global

শুধু UI menu লুকানো authorization নয়। প্রতিটি API endpoint এবং data query-তে server-side authorization প্রয়োজন।


GAP-04: User এবং Employee relationship ভুলভাবে কঠোর

বর্তমান ER diagram-এ USER ||--|| EMPLOYEE বাধ্যতামূলক one-to-one relationship দেখানো হয়েছে।

কিন্তু বাস্তবে:

  • Employee record account invitation-এর আগে তৈরি হতে পারে।
  • Super Admin user employee নাও হতে পারেন।
  • Recruiter বা external payroll user employee নাও হতে পারেন।
  • Terminated employee record থাকবে, কিন্তু user account disabled হতে পারে।

Recommended relationship

text
User 0..1 ---- 0..1 Employee

আরও ভালো model:

  • users: authentication identity
  • employees: HR identity
  • user_employee_links: প্রয়োজন হলে explicit mapping
  • employment_records: employment lifecycle
  • user_sessions: active sessions
  • external_identities: Google/Microsoft SSO mapping

GAP-05: Approval workflow সংজ্ঞায়িত নয়

Leave এবং attendance correction-এর জন্য multi-level approval বলা হয়েছে, কিন্তু নিচের নিয়মগুলো নেই:

  • Approver কীভাবে নির্ধারিত হবে?
  • Manager অনুপস্থিত থাকলে কী হবে?
  • একই employee-এর জন্য একাধিক approver থাকলে sequence কী?
  • HR override করলে original approver-এর status কী হবে?
  • Request withdraw বা cancel করা যাবে কি?
  • Approval deadline বা escalation থাকবে কি?
  • Approver নিজের request approve করতে পারবেন কি?

Recommended workflow model

Shared approval engine ব্যবহার করা উচিত:

  • approval_definitions
  • approval_definition_steps
  • approval_instances
  • approval_instance_steps
  • approval_actions

প্রাথমিক MVP rule:

  1. Employee request submit করবেন।
  2. প্রথম approver হবেন active primary manager।
  3. Policy অনুযায়ী HR second-level approver হতে পারবেন।
  4. Approver নিজের request approve করতে পারবেন না।
  5. Pending request employee withdraw করতে পারবেন।
  6. Approved leave শুরু হওয়ার আগে cancellation request করা যাবে।
  7. HR override-এর জন্য আলাদা permission এবং mandatory reason প্রয়োজন।
  8. প্রতিটি action audit log-এ থাকবে।

GAP-06: Attendance calculation rules অসম্পূর্ণ

বর্তমান requirements সাধারণ day shift-এর জন্য যথেষ্ট, কিন্তু production attendance system-এর জন্য নিচের rule অনুপস্থিত:

  • Overnight shift
  • Split shift
  • Break in এবং break out
  • Multiple check-in attempt
  • Missing check-out
  • Weekend work
  • Holiday work
  • Shift change
  • Grace period calculation
  • Overtime approval
  • Employee timezone বনাম branch timezone
  • Device clock manipulation
  • Duplicate mobile submission
  • Offline submission
  • Remote employee location policy

Recommended baseline

Attendance data দুই স্তরে রাখতে হবে:

Raw attendance events

text
attendance_events - check_in - check_out - break_start - break_end - manual_adjustment

Calculated daily record

text
attendance_days - work_date - first_check_in - last_check_out - worked_minutes - late_minutes - early_exit_minutes - overtime_minutes - status - calculation_version

গুরুত্বপূর্ণ নিয়ম:

  • Server timestamp হবে authoritative timestamp।
  • Client timestamp আলাদাভাবে diagnostic field হিসেবে রাখা যাবে।
  • প্রতিটি mobile action-এ idempotency key ব্যবহার করতে হবে।
  • Overnight shift-এর work_date shift start date অনুযায়ী নির্ধারণ করতে হবে।
  • Missing punch record incomplete status পাবে।
  • Overtime payroll-এ পাঠানোর আগে approved হতে হবে।
  • GPS-এর সঙ্গে accuracy radius সংরক্ষণ করতে হবে।
  • Location unavailable হলে policy অনুযায়ী block, warning বা exception flow চালু হবে।

GAP-07: Leave balance engine-এর accounting model অনুপস্থিত

শুধু LeaveBalance table ব্যবহার করলে accrual, carry-forward, adjustment, cancellation এবং historical reconciliation কঠিন হবে।

Recommended model

Leave balance একটি immutable ledger থেকে গণনা করতে হবে।

text
leave_ledger - opening_balance - accrual - approved_leave - cancellation_reversal - expiry - manual_adjustment - carry_forward

প্রয়োজনীয় business rules:

  • Accrual monthly, annual বা joining anniversary ভিত্তিক হতে পারে।
  • Mid-year joining-এর জন্য proration rule প্রয়োজন।
  • Probation period-এ leave eligibility নির্ধারণ করতে হবে।
  • Negative balance allowed কি না নির্ধারণ করতে হবে।
  • Unpaid leave balance ছাড়াই apply করা যাবে।
  • Half-day-এর পাশাপাশি hourly বা quarter-day support প্রয়োজন কি না নির্ধারণ করতে হবে।
  • Holiday ও weekend leave duration-এ count হবে কি না policy-driven হতে হবে।
  • Approved leave cancel হলে ledger reversal তৈরি হবে।
  • Termination-এর সময় unused leave handling policy প্রয়োজন।
  • Leave balance backdated edit করলে recalculation এবং audit প্রয়োজন।

GAP-08: Measurable non-functional requirements নেই

“Quickly”, “minimal delay” এবং “responsive” testable acceptance criteria নয়।

Recommended initial NFR baseline

এই সংখ্যাগুলো capacity test-এর পরে সংশোধন করা যাবে:

  • সাধারণ read API-এর p95 response time: সর্বোচ্চ 500 ms
  • সাধারণ write API-এর p95 response time: সর্বোচ্চ 800 ms
  • Clock-in/out end-to-end response: সর্বোচ্চ 2 seconds
  • Dashboard initial load: সর্বোচ্চ 3 seconds under normal load
  • Monthly production availability target: 99.9%
  • Recovery Point Objective: সর্বোচ্চ 15 minutes
  • Recovery Time Objective: সর্বোচ্চ 2 hours
  • Critical actions-এর audit persistence: transaction-এর অংশ
  • Large report export: asynchronous job
  • File upload size এবং allowed type explicit configuration
  • Tenant isolation test: mandatory release gate
  • Accessibility target: WCAG 2.1 AA baseline
  • Date/time storage: UTC timestamp এবং separate local work date

4. P1 high-priority gaps

4.1 Employee lifecycle

বর্তমান status list আছে, কিন্তু lifecycle transition rule নেই।

প্রস্তাবিত state:

text
draft invited probation active notice resigned terminated archived

Account status এবং employment status আলাদা রাখতে হবে।

উদাহরণ:

  • Employee notice status-এ থেকেও login করতে পারবেন।
  • Employee terminated হলে policy অনুযায়ী account disable হবে।
  • Rehire করলে পুরোনো employee record overwrite না করে নতুন employment record তৈরি করতে হবে।
  • Department, designation, salary band এবং manager পরিবর্তন effective-dated history হিসেবে রাখতে হবে।

প্রয়োজনীয় additional tables:

  • employment_records
  • employee_assignments
  • employee_manager_history
  • employee_status_history

4.2 Employee code generation

Unique employee ID generation উল্লেখ করা হয়েছে, কিন্তু format বা concurrency rule নেই।

Recommended configuration:

text
Prefix: EMP Sequence: 000001 Scope: Company বা Branch Example: EMP-000123

Database sequence বা transactional counter ব্যবহার করতে হবে। Application-side “last number + 1” ব্যবহার করা যাবে না।


4.3 Organization structure history

Employee transfer হলে পুরোনো attendance ও reports কোন branch/department-এ গণনা হবে তা নির্ধারিত নয়।

Recommended rule:

  • Current profile বর্তমান assignment দেখাবে।
  • Historical report event date-এর effective assignment ব্যবহার করবে।
  • Transfer history কখনো overwrite করা যাবে না।

4.4 Leave request day breakdown

শুধু start date এবং end date রাখলে half-day, holiday exclusion এবং mixed-duration leave support করা কঠিন।

প্রয়োজন:

text
leave_requests leave_request_days

leave_request_days-এ থাকতে পারে:

  • leave_date
  • duration
  • deducted_units
  • holiday_flag
  • weekend_flag
  • policy_result

4.5 Holiday calendar assignment

Holiday শুধু company-level entity হিসেবে যথেষ্ট নয়।

প্রয়োজন:

  • Holiday calendar
  • Calendar entries
  • Branch assignment
  • Employee group assignment
  • Optional holiday selection
  • Regional holiday override

4.6 Shift assignment

Shift entity আছে, কিন্তু employee-এর shift history নেই।

প্রয়োজন:

  • shift_assignments
  • effective_from
  • effective_to
  • assignment_type
  • rotation_pattern

Shift পরিবর্তন historical attendance recalculation করবে কি না, সেটিও rule হিসেবে নির্ধারণ করতে হবে।


4.7 GPS attendance privacy ও abuse control

GPS attendance-এর জন্য প্রয়োজন:

  • Employee consent notice
  • Location permission handling
  • Location retention period
  • Geofence radius
  • Accuracy threshold
  • Mock-location detection policy
  • Location capture failure behavior
  • HR access restriction
  • Location export restriction
  • Audit trail

Location data প্রয়োজনের অতিরিক্ত সময় সংরক্ষণ করা উচিত নয়।


4.8 Notification delivery model

বর্তমানে notification entity আছে, কিন্তু channel delivery tracking নেই।

Recommended model:

  • notifications: user-facing message
  • notification_deliveries: push/email/in-app channel result
  • device_tokens: mobile push registration
  • notification_preferences
  • notification_templates

Delivery status:

text
queued sent delivered failed read

Domain event এবং transactional outbox pattern ব্যবহার করলে database commit হওয়ার আগে notification চলে যাওয়ার ঝুঁকি কমবে।


4.9 Documents এবং file security

Employee document upload-এর জন্য নিচের requirement প্রয়োজন:

  • Allowed file type
  • Maximum size
  • Virus বা malware scan
  • File category
  • Expiry date
  • Document owner
  • Visibility scope
  • Version
  • Retention policy
  • Signed download URL
  • Download audit
  • Sensitive document classification

ফাইল সরাসরি public URL দিয়ে serve করা যাবে না।


4.10 Audit log specification

Audit log শুধু “record sensitive changes” বললে যথেষ্ট নয়।

প্রতিটি log-এ থাকতে হবে:

  • Actor user
  • Company
  • Action
  • Resource type
  • Resource ID
  • Before value
  • After value
  • Request ID
  • IP address
  • Device বা user agent
  • Timestamp
  • Override reason
  • Impersonation context

Password, token এবং অত্যন্ত sensitive value audit payload-এ রাখা যাবে না।

Audit log সাধারণ admin user পরিবর্তন বা delete করতে পারবেন না।


4.11 Reporting definitions

“Present”, “Absent”, “Late” এবং “Headcount” metric-এর calculation definition প্রয়োজন।

উদাহরণ:

  • Headcount কি selected date-এর active employment count?
  • Approved leave কি absent count থেকে বাদ যাবে?
  • Missing check-out কি present নাকি exception?
  • Holiday-তে clock-in করলে present নাকি holiday-work?
  • Department report current department নাকি historical assignment ব্যবহার করবে?

প্রতিটি report-এর data dictionary তৈরি করতে হবে।


4.12 API specification gap

বর্তমান API section endpoint inventory হিসেবে ভালো, কিন্তু developer contract হিসেবে অসম্পূর্ণ।

নিচের বিষয়গুলো প্রতিটি endpoint-এ প্রয়োজন:

  • Authorization permission
  • Request schema
  • Response schema
  • Validation rules
  • Business error codes
  • Pagination behavior
  • Sorting behavior
  • Idempotency rule
  • Audit behavior
  • Rate limit
  • State transition
  • Example success response
  • Example error response

5. ER model corrections

5.1 Designation tenant ownership

DESIGNATION table-এ company_id প্রয়োজন।

5.2 Role normalization

permission_set string বাদ দিয়ে normalized permission tables ব্যবহার করতে হবে।

5.3 Attendance work date

ATTENDANCE_RECORD-এ explicit work_date প্রয়োজন।

5.4 Payslip component relationship

একটি payslip-এ অনেক salary component এবং একই component অনেক payslip-এ থাকতে পারে।

সঠিক model:

text
payslips payslip_line_items salary_components

5.5 Employee document schema

প্রয়োজনীয় field:

text
file_asset_id document_type document_number issued_on expires_on visibility verification_status version

5.6 Manager relationship

শুধু manager_employee_id current manager দেখাতে পারে, history নয়। Historical reporting-এর জন্য আলাদা manager assignment table প্রয়োজন।

5.7 Notification schema

Employee-এর সঙ্গে direct notification relationship যথেষ্ট নয়। User account এবং device delivery relationship প্রয়োজন।

5.8 Candidate conversion

Candidate থেকে employee conversion-এর ক্ষেত্রে duplicate email, previous application এবং offer acceptance state define করতে হবে।

5.9 Soft delete

Soft delete ব্যবহার করা হলেও unique constraint এবং restore behavior স্পষ্ট হতে হবে। Audit-critical data physical delete করা উচিত নয়।


6. Security gaps

নিচের security controls requirement-এ যুক্ত করা প্রয়োজন:

  1. Password complexity এবং password reuse policy
  2. Login rate limiting
  3. Temporary account lockout
  4. MFA recovery codes
  5. Session revocation
  6. Device/session listing
  7. Refresh-token rotation
  8. SSO identity linking rules
  9. CSRF protection যেখানে cookie-based auth ব্যবহৃত হবে
  10. File upload scanning
  11. Field-level masking
  12. Encryption key management
  13. Secret rotation
  14. Database backup encryption
  15. PII logging prevention
  16. Dependency vulnerability scanning
  17. Static application security testing
  18. Dynamic security testing
  19. Privileged action re-authentication
  20. Production support impersonation audit

Payroll বা bank information যোগ হলে আরও শক্ত field-level encryption এবং access segregation প্রয়োজন হবে।


7. Mobile-specific gaps

Mobile MVP-এর জন্য নিচের সিদ্ধান্ত প্রয়োজন:

  • Minimum supported Android এবং iOS policy
  • App update policy
  • Rooted বা jailbroken device handling
  • Push token refresh
  • Lost device session revocation
  • Biometric failure fallback
  • Background location ব্যবহার হবে কি না
  • Offline clock-in অনুমোদিত কি না
  • Poor network-এ duplicate request handling
  • Cached data encryption
  • Screenshot restriction sensitive screen-এ প্রয়োজন কি না
  • Deep-link authorization
  • Mobile crash reporting
  • Clock-in button-এর loading এবং retry behavior

Recommended MVP decision

Offline clock-in MVP-তে অনুমোদন না করাই নিরাপদ। Network না থাকলে app user-কে correction request workflow দেখাবে।

Static policy এবং profile data encrypted local cache-এ রাখা যেতে পারে।


8. Phase 2 module gaps

Payroll

Payroll module বর্তমানে high-level। Development শুরুর আগে country-specific specification প্রয়োজন:

  • Tax rule
  • Social contribution
  • Proration
  • Arrear
  • Bonus
  • Loan
  • Reimbursement
  • Final settlement
  • Retroactive adjustment
  • Payroll lock
  • Bank file format
  • Accounting journal
  • Payslip approval
  • Payroll reversal

Payroll compliance specification ছাড়া payroll engine build শুরু করা উচিত নয়।

Recruitment

প্রয়োজন:

  • Candidate consent
  • Duplicate candidate handling
  • Resume parsing policy
  • Interview timezone
  • Feedback visibility
  • Offer approval
  • Rejection retention
  • Candidate data deletion

Performance

প্রয়োজন:

  • Rating scale
  • Calibration
  • Review visibility
  • Goal weight
  • Review reopening
  • Reviewer anonymity
  • Final rating approval

Part B: Recommended Product and Technical Decisions

9. MVP scope baseline

Included

  • Company, branch, department, designation
  • User authentication
  • Google/Microsoft SSO
  • Optional role-based MFA
  • RBAC এবং scoped authorization
  • Employee creation, update এবং lifecycle
  • Manager hierarchy
  • Shift এবং holiday configuration
  • Web/mobile attendance
  • Attendance correction
  • Leave policy, balance এবং request
  • Manager approval
  • Notifications এবং announcements
  • Basic employee documents
  • HR, manager এবং employee dashboard
  • Attendance, leave এবং headcount reports
  • CSV/XLSX export

  • Mobile biometric unlock

Excluded

  • Payroll calculation
  • Recruitment
  • Performance review
  • Advanced onboarding
  • Asset management
  • Offline attendance
  • Biometric attendance machine integration
  • Custom workflow builder
  • Multi-country tax localization

10. Recommended architecture

MVP-এর জন্য microservice architecture-এর পরিবর্তে modular monolith ব্যবহার করা সবচেয়ে বাস্তবসম্মত।

এতে module boundary পরিষ্কার থাকবে, কিন্তু deployment ও debugging তুলনামূলক সহজ হবে।

Recommended technology baseline

  • Web: Next.js এবং TypeScript
  • Mobile: React Native এবং TypeScript
  • Backend: NestJS এবং TypeScript
  • Database: PostgreSQL
  • Cache এবং distributed lock: Redis
  • Background jobs: Redis-backed queue
  • File storage: S3-compatible object storage
  • API documentation: OpenAPI
  • Authentication: OIDC-compatible identity provider অথবা secure internal auth service
  • Containerization: Docker
  • Infrastructure: Infrastructure as Code
  • Monitoring: Centralized logs, metrics, traces এবং alerting

একই language ecosystem ব্যবহারের ফলে shared type, validation schema এবং developer context switching কমবে।

Backend domain modules

text
identity authorization organization employees attendance leave approvals notifications announcements documents reports audit settings

Shared platform components

text
API gateway or application API layer background worker event/outbox processor file service notification adapters audit service report export worker

11. Suggested repository structure

text
/apps /web /mobile /api /worker /packages /api-client /contracts /ui-web /ui-mobile /validation /permissions /date-time /testing /infrastructure /docker /terraform-or-equivalent /monitoring /docs /adr /api /data-dictionary /runbooks

API request/response DTO mobile বা web source code থেকে আলাদাভাবে shared contract package-এ রাখা উচিত।


Part C: Developer-ready Data Model

12. Core schema groups

Identity এবং access

  • companies
  • users
  • external_identities
  • user_sessions
  • mfa_methods
  • roles
  • permissions
  • role_permissions
  • user_role_assignments
  • role_scope_assignments

Organization

  • branches
  • departments
  • designations
  • holiday_calendars
  • holidays
  • holiday_calendar_assignments

Employee

  • employees
  • employment_records
  • employee_assignments
  • employee_manager_assignments
  • employee_contacts
  • employee_emergency_contacts
  • employee_documents
  • file_assets

Attendance

  • shifts
  • shift_assignments
  • attendance_events
  • attendance_days
  • attendance_correction_requests
  • attendance_correction_actions
  • overtime_requests

Leave

  • leave_types
  • leave_policies
  • leave_policy_assignments
  • leave_ledger
  • leave_requests
  • leave_request_days

Shared workflow

  • approval_definitions
  • approval_definition_steps
  • approval_instances
  • approval_instance_steps
  • approval_actions

Communication

  • announcements
  • announcement_audiences
  • notifications
  • notification_deliveries
  • notification_preferences
  • device_tokens

Governance

  • audit_logs
  • system_settings
  • report_export_jobs
  • idempotency_records
  • outbox_events

13. Database implementation rules

  1. সব primary key UUID হবে।
  2. সব business table-এ company_id থাকবে।
  3. সব mutable table-এ created_at, updated_at, created_by এবং updated_by থাকবে।
  4. প্রয়োজনীয় table-এ deleted_at থাকবে।
  5. Money field-এর জন্য floating point ব্যবহার করা যাবে না।
  6. Timestamp UTC-তে সংরক্ষিত হবে।
  7. Attendance এবং leave-এর জন্য local date আলাদাভাবে সংরক্ষণ করতে হবে।
  8. গুরুত্বপূর্ণ update-এর জন্য optimistic version field ব্যবহার করা হবে।
  9. Database constraint business validation-এর শেষ নিরাপত্তা স্তর হবে।
  10. Migration production deployment-এর আগে staging-এ পরীক্ষা করতে হবে।
  11. Audit-critical table physical delete করা যাবে না।
  12. Payroll future module-এর জন্য decimal precision আগেই standardize করতে হবে।

Part D: API Implementation Standard

14. API baseline

Base path:

text
/api/v1

Authentication

text
Authorization: Bearer <token>

Required headers

text
X-Request-Id Idempotency-Key Accept-Language

Idempotency-Key শুধু duplicate-sensitive write operation-এ বাধ্যতামূলক হবে।

Date and time

  • Timestamp: ISO 8601 with timezone
  • Server storage: UTC
  • Business date: YYYY-MM-DD
  • Client timezone: informational
  • Company/branch timezone: policy source

15. Important API corrections

Employee self check-in endpoint-এ client থেকে employeeId নেওয়া উচিত নয়।

Recommended endpoint:

text
POST /api/v1/me/attendance/check-in POST /api/v1/me/attendance/check-out

Authorized admin manual adjustment-এর জন্য আলাদা endpoint:

text
POST /api/v1/employees/{employeeId}/attendance-adjustments

Leave approval endpoint action-oriented হতে পারে:

text
POST /api/v1/leave-requests/{id}/actions/approve POST /api/v1/leave-requests/{id}/actions/reject POST /api/v1/leave-requests/{id}/actions/withdraw POST /api/v1/leave-requests/{id}/actions/cancel

একই pattern attendance correction-এর ক্ষেত্রেও ব্যবহার করা উচিত।


16. Error contract

Error response-এ machine-readable code থাকা প্রয়োজন:

json
{ "success": false, "code": "LEAVE_INSUFFICIENT_BALANCE", "message": "Available leave balance is insufficient.", "errors": [], "requestId": "uuid" }

Recommended business codes:

text
AUTH_INVALID_CREDENTIALS AUTH_MFA_REQUIRED AUTH_SESSION_EXPIRED ACCESS_SCOPE_DENIED EMPLOYEE_CODE_CONFLICT ATTENDANCE_ALREADY_CHECKED_IN ATTENDANCE_NO_OPEN_SESSION ATTENDANCE_OUTSIDE_GEOFENCE LEAVE_INSUFFICIENT_BALANCE LEAVE_OVERLAPPING_REQUEST LEAVE_POLICY_NOT_ASSIGNED APPROVAL_ALREADY_COMPLETED RESOURCE_VERSION_CONFLICT

17. Pagination and filtering

List API-তে standard format ব্যবহার করতে হবে:

text
page limit sort search filter[field]

Maximum limit server-side enforce করতে হবে।

Large dataset-এর জন্য ভবিষ্যতে cursor pagination ব্যবহার করা যেতে পারে, তবে MVP admin table-এর জন্য consistent offset pagination যথেষ্ট।


18. API concurrency rules

একই leave request দুই approver একই সময়ে approve করলে double action ঠেকাতে:

  • Database transaction
  • Row locking অথবা optimistic version
  • State transition validation

ব্যবহার করতে হবে।

Client stale resource update করলে 409 RESOURCE_VERSION_CONFLICT return করা উচিত।


Part E: State Machines

19. Leave request state

text
draft submitted pending_approval approved rejected withdrawn cancellation_pending cancelled

Allowed transition ছাড়া direct status update নিষিদ্ধ থাকবে।


20. Attendance correction state

text
submitted pending_approval approved rejected withdrawn

Approved correction raw event delete করবে না। Adjustment event এবং recalculated attendance day তৈরি করবে।


21. Employee account state

text
invited active locked disabled

Employment status আলাদা হবে:

text
draft probation active notice resigned terminated

22. Attendance day state

text
not_scheduled present late absent on_leave holiday weekend incomplete corrected

Late, present এবং overtime আলাদা dimensions হিসেবেও রাখা যেতে পারে; একটি single status-এর ওপর সব reporting নির্ভর করা উচিত নয়।


Part F: Developer-ready Delivery Plan

23. Delivery approach

Recommended plan:

  • Sprint length: 2 weeks
  • Foundation Sprint: 1–2 weeks

Final recommendation

বর্তমান SRS বাতিল বা পুনরায় শুরু করার প্রয়োজন নেই। এটিকে Product Requirements Baseline হিসেবে রেখে উপরের gap resolution এবং technical decision-গুলো একটি supplementary specification হিসেবে অনুমোদন করা উচিত।

Development-এর সবচেয়ে নিরাপদ ও দ্রুত পথ হবে:

  1. প্রথমে Sprint 0 সম্পন্ন করা।
  2. Multi-tenant modular monolith architecture গ্রহণ করা।
  3. Permission, attendance এবং leave engine-কে core domain হিসেবে অগ্রাধিকার দেওয়া।
  4. Raw attendance event এবং leave ledger immutable রাখা।
  5. Phase 2 module MVP codebase-এ আংশিকভাবে build না করা।
  6. OpenAPI contract এবং automated permission test-কে release gate করা।
  7. Sprint 7 শেষে limited pilot organization দিয়ে production rollout শুরু করা।

এই approach অনুসরণ করলে HRMS MVP তুলনামূলক কম rework, পরিষ্কার module boundary এবং ভবিষ্যৎ payroll, recruitment ও performance expansion-এর উপযোগী foundation নিয়ে তৈরি হবে। :::

পরবর্তী যৌক্তিক ধাপ হলো এই পরিকল্পনাকে Jira-ready epics, stories, subtasks এবং পূর্ণ OpenAPI 3.0 contract-এ ভেঙে development board প্রস্তুত করা।
