Understanding What Is, Designing What Works

Bridging the gap between strategy and execution

TAG’s approach to Business Analysis & Architecture is bridging the gap between strategy & execution, and between business & IT. Our business analysts and architects dive deep into your organisation, uncover opportunities, and co-create tailored solutions that align processes, capabilities and technologies with your business needs and strategic goals.

From insight to clear requirements

Strong solutions start with understanding your business. TAG’s business analysts dive into your organisation to map processes, identify pain points, and capture business needs with precision. From there, we help you define the “to-be” state: a clear, structured view of how your organisation should operate in the future. Together, we translate ambitions into practical needs, outline new workflows, redesign interactions between teams, and determine the capabilities and systems required to support your strategy.

Bridging strategy and execution

Filling the gap between “as is” and “to be”. Based on our analysis and considering both existing and build-to-suit solutions, we design a solution to solve the gap. We design, prototype, and fine-tune based on our experience and with your approval in every step. We are only satisfied when the project is finished and our customer is satisfied.

Guiding implementation and ensuring adoption

We don’t stop at analysis or design. TAG consultants remain involved during execution: facilitating decisions, ensuring alignment, coordinating stakeholders, and monitoring progress. We support testing, training, change adoption, and aftercare to guarantee that the chosen solution becomes part of your daily operations and delivers the expected impact.

What does TAG offer?
Business Analysis

A TAG business analyst helps you understand your organisation from the inside out. We map your current processes, uncover operational challenges, and capture your business needs with clarity and precision. By engaging stakeholders and challenging assumptions, we build a complete and honest picture of your “as is” situation, the essential starting point for any meaningful improvement.

From there, we help you shape the “to be” state: a realistic and future-proof view of how your workflows, systems or organisation should evolve. We translate this into concrete, validated requirements and guide you in selecting the best-fit solution, whether it’s an existing tool or a build-to-suit alternative. Throughout the journey, we stay close to your teams, supporting design, implementation and adoption to ensure the solution truly works in practice.

What makes TAG different is our blend of an analytical precision, an engineering mindset, and a hands-on attitude. We are tool-independent, unbiased, and pragmatic. Our consultants bring experience from multiple industries while tailoring every step to your unique context, ensuring that the solution is not only well-designed, but also successfully delivered and fully embraced by your organisation.

What are the benefits of business analysis & architecture?

Tackling a business problem efficiently requires a strategic approach. A business analyst dives into your company’s operations to map out your processes and identify what business areas can be improved. A business architect can offer you the much-needed insight and advice to clarify your strategy and confidently execute your plans.

But that’s not all. To ensure a solution’s success, a business analyst also bridges the gap between your strategy and the teams that execute it, making sure all stakeholders are aligned. While a business architect helps you connect the dots and expose change impacts. Both profiles help you create more effective transformation roadmaps and determine what actions you need to take to align every level within your company with your overarching strategy.

Where TAG makes the difference

Hiring a TAG consultant can offer you a fresh perspective on your business structure and processes. Our consultants have supported businesses of all sizes and in different industries, providing them with valuable experience and best practices which they’ll happily implement in your work environment.

After we’ve determined the next steps for your business strategy, we can go a step further and offer hands-on support during the execution of the roadmap, or by zooming in on specific business problems and solving them with tailored solutions. We pride ourselves on being tech independent. We don’t narrow ourselves by applying just one method or framework to solve your business problems. We’re open-minded and select the best tools available to meet your specific business needs.
