Chapter 1: Introduction to IT Solution Architecture

Every so often, questions arise like, "How can Sales and Pre-Sales roles collaborate effectively?" or "How can a Sales professional engage with Pre-Sales without extensive technical expertise?" This guide aims to provide a structured approach to constructing a robust IT solution based on my experiences.

The process consists of five key steps:

1. Business Architecture — Aligning Creativity with Business Objectives
2. Application Architecture — Addressing Key Concerns
3. Data Architecture — Understanding Required Data Models and Designs
4. Infrastructure Consideration — Building on the Above Architectures
5. Summary Sheet — Compiling All Necessary Information in One Place

This comprehensive journey spans from gathering requirements to finalizing quotations and Scope of Work. Such practices are commonly observed among Sales, Pre-Sales, and Business Analysts. Below, I will outline the roles involved in each section.

Aligning Creativity with Business Objectives

In any project discussion, there is typically a defined Business Objective. By asking the right questions to uncover client needs, we can begin drafting the Business Architecture. This concept refers to "a describable level of processes and logic within the architecture," aiming to map requirements into a high-level overview of Products/Services.

The goal here is to identify pain points and expected outcomes.

Addressing Key Concerns

Application Architecture focuses on the processes and logic at the product/service level. It often involves integration steps where various microservices/products are combined, leading to potential setup challenges. This phase acts as a Proof-of-Concept (POC) to validate integration obstacles.

Additionally, it establishes a "modular" approach to architecture. This modularity involves:

• Cross-cutting concerns: Each module must adhere to specific rules within itself, such as security and design patterns.
• Inter-layer concerns: Similar to OpenAPI, these expose subsets of processes and data for other modules.

The aim is to ensure that the architecture remains functional.

Understanding Required Data Models and Designs

Once the Business and Application Architectures are defined, we can develop the Data Architecture through Implementation Specifications. This involves designing the Data Structure to meet the necessary functions and specifications.

Data Architecture encompasses the data formats required to facilitate each function within the solution design, such as JSON and table schemas. The objective is to create a "Tracking Plan" that maps out the data model based on the required functions and features.

Roles Involved: Pre-Sales (80%), Sales (20%)

Building on the Above Architectures

With the Application and Data Architectures mapped out, establishing the Infrastructure becomes more intuitive and centers around efficiency and maintenance discussions.

Industry practices typically align with client preferences regarding deployment (Cloud/Hybrid/On-Premise) and compliance policies. The goal is to integrate application and data requirements into a well-structured infrastructure.

Roles Involved: Pre-Sales (80%), Sales (20%)

Compiling All Necessary Information

Ultimately, project decisions are financial. After thorough research and architectural planning, the Summary Sheet outlines the required deliverables and budget for selected services/products. This document serves as the final list of deliverables and the budget proposal, also known as the Scope of Work.

Chapter 2: Practical Insights and Reflections

In the video titled "Solution Architecture Document (S.A.D) Full Example - Design Doc Explanation," viewers can gain insights into creating effective solution architecture documents.

The video "Solutions Architect Tips: How to Build Your First Architecture Diagram" offers practical tips for drafting effective architecture diagrams.

Closing Thoughts

IT solutions can be approached in various ways. Throughout my career, I've found that no matter how diverse the IT solution may be, this guide serves as a blueprint to streamline the process. It helps identify what is missing and what needs addressing, ultimately boosting confidence in project outcomes.

As projects progress, challenges may arise unexpectedly. Committing to a project is akin to taking a leap of faith, requiring a solid rationale and confidence in its success. This guide aims to bolster your confidence before diving into any project.
