Network Configuration Diagram Examples 

This is an example of a Network Configuration Diagram.

Focusing on Layer 2 (L2), Layer 3 (L3), Firewalls, VPNs, and Zero Trust, this document presents network designs in a clear and easy-to-understand visual format. It covers key design elements such as VLAN segmentation, routing control, redundancy, traffic control, encryption, authentication, and access management.

The document also organizes the roles of each network component, communication paths, monitoring methods, and important design considerations. It serves as a practical reference for network proposals, high-level design documents, and network architecture documentation.

Database Design, API Integration & Operations Documentation 

This document provides sample database design, API integration, state transition, batch and job operation, monitoring, disaster recovery (DR), and backup diagrams and design documentation required for system development and operational design.

These practical documents can be easily edited and customized to meet specific business requirements and operational requirements, making them valuable resources for system design, implementation, and ongoing operations.

Examples of System Migration & Cutover Planning Documentation 

This is an example of a planning document that covers the selection of migration approaches required for system replacement, comparison of current and target systems, data migration, rehearsals, production cutover, rollback, Go/No-Go decisions, and post-migration hypercare. In addition to work procedures, it clearly defines start and completion criteria, responsible parties, decision criteria, and required evidence. It can be used as a system migration plan or cutover plan.

Examples of Security Architecture Diagrams 

This is an example of security design documentation that clearly visualizes identity and access management, multi-factor authentication (MFA), endpoint security, Web and API protection, SIEM and SOC, privileged access management, and incident response. It organizes the roles of each security control, trust boundaries, control points, and monitoring and response methods. It can be used for security proposals, high-level design documents, and architecture design documents.

Infrastructure Architecture Diagrams 

This is an example of infrastructure design documentation that clearly visualizes servers, virtual infrastructure, storage, containers, and monitoring, including Web, application, and database architectures; VMware, Hyper-V, and Nutanix; SAN and NAS; Docker and Kubernetes; and integrated monitoring. It organizes communication paths, redundancy, data protection, management paths, monitoring methods, and system behavior during failures. It can be used for infrastructure proposals, high-level design documents, and architecture design documents.

Examples of Application Architecture & Development Design Diagrams 

This is an example of development design documentation that clearly visualizes the overall application architecture, three-tier and MVC architectures, components, microservices, sequence diagrams, event and message integration, authentication and authorization, and exception handling. It organizes the roles of each function, dependencies, processing sequences, data flows, system behavior during failures, and key design considerations. It can be used for high-level design documents, application design documents, and development specifications.

Example of a System Modernization Proposal 

This is an example proposal that identifies key challenges such as aging systems, expiring support, performance limitations, security risks, and operational workload. It covers the modernization policy, target system architecture, migration and cutover plan, implementation schedule, project organization, estimated costs, and expected benefits. It clearly illustrates the differences between the current and target systems, including redundancy, monitoring, backup, and safe migration methods, and can be used for system modernization and infrastructure renewal proposals. 

Examples of Test Planning & Quality Management Documentation 

This is an example of test planning and quality management documentation covering unit, integration, system, business scenario, performance and load, resilience and recovery, security, and user acceptance testing. It clearly defines the test scope, entry and exit criteria, quality metrics, defect management, test evidence, residual risks, and release decision criteria. It can be used as a master test plan, quality management plan, or acceptance and completion assessment document.

Examples of Screen, UI & UX Design Documentation 

This is an example of screen, UI, and UX design documentation that clearly organizes the screen inventory and information architecture, screen flows, wireframes, input validation, role-based displays, error messages, responsive design, accessibility, and user journeys. It defines intuitive user flows, key considerations for design, implementation, and user validation, and acceptance criteria. It can be used as screen design documentation, UI/UX design documentation, or development specifications.

Examples of Requirements Definition & Business Process Design Documentation 

This is an example of requirements definition and business process design documentation covering the background and objectives of system implementation, project scope and stakeholders, current and target business processes, business issues and improvement policies, functional and non-functional requirements, security requirements, data requirements, and external system integration. It links business issues and measurable KPIs to requirements, design, testing, and approval criteria, helping stakeholders establish a common understanding. It can be used as a requirements specification, business process design document, or system implementation plan.

Examples of Detailed Design & Program Specifications
