Data Analytics

Reporting and Data Visualization Services

Deliver fast, trustworthy dashboards and self-service analytics on a governed semantic layer, so every team works from the same numbers.

Dashboards People Trust and Actually Use

Most organizations already own a BI tool. What they often lack is a reliable foundation underneath it: shared metric definitions, clean dimensional models, row-level security and refresh pipelines that do not break. Without that foundation, every new report is built from scratch, numbers disagree, performance suffers and users quietly go back to exporting data into Excel.

Hanoi Technology builds reporting the other way round. We start with the decisions users need to make, design a governed semantic model with certified KPIs, and then create clear, fast dashboards on Power BI, Tableau, Looker or Qlik. Governance and adoption programs keep the environment healthy as self-service grows.

The Challenge

Why BI Environments Lose User Trust

Reporting problems are rarely about chart types; they are about foundations, governance and design.

Multiple Versions of Every KPI

Revenue, margin or active customers are calculated differently across reports built by different teams. Users stop trusting any of them.

Slow and Fragile Reports

Reports built directly on raw tables with complex logic in every visual load slowly, time out during refresh and break when source systems change.

Report Sprawl

Hundreds of workspaces, duplicated datasets and abandoned reports make it hard to find the right one and drive up licensing, capacity and support costs.

Cluttered, Unclear Design

Dashboards packed with gauges, colors and tables bury the message. Users cannot tell at a glance whether performance is on track or what needs attention.

Business Value

The Impact of Governed Self-Service BI

Consistent, Certified Metrics

A shared semantic model with documented definitions means every report and analyst uses the same logic for each KPI.

Faster Insight

Optimized models and aggregations make dashboards respond in seconds, encouraging exploration rather than exports.

Self-Service Without Chaos

Business analysts build their own reports on certified datasets, within clear guardrails for workspaces, sharing and publishing.

Clear, Actionable Design

Dashboards designed around questions and thresholds highlight exceptions and trends so users know where to act.

Secure Data Access

Row-level and object-level security ensure each user sees exactly the data they are entitled to, across regions, entities or customers.

Lower BI Running Costs

Consolidating datasets, retiring unused content and right-sizing capacity reduce license and compute spending.

Design for the Question, Not the Data

A dashboard succeeds when a user can answer their key question within seconds. We design every page around a small number of decisions, use visual hierarchy and consistent layouts, and add drill-downs only where they lead to an action. Good design is not decoration; it is what turns a report into a management tool.

Our Approach

Our Reporting Delivery Approach

Short iterations that keep users involved and numbers reconciled from day one.

  1. 01

    Understand Users and Decisions

    We interview report consumers to capture their key questions, decisions, refresh needs and the KPIs they rely on today.

    Deliverables: User personas and questions · KPI inventory

  2. 02

    Model the Data

    We design and build the dimensional model and semantic layer, agreeing on definitions with data owners before any visuals are built.

    Deliverables: Semantic model · Data quality checks

  3. 03

    Prototype and Iterate

    We share wireframes and clickable prototypes, collect feedback in short cycles and refine layout and interactions before full build.

    Deliverables: Wireframes and prototypes · Design guidelines

  4. 04

    Validate and Publish

    We reconcile figures against trusted sources, test performance and security, and publish through controlled deployment pipelines.

    Deliverables: Reconciliation report · Performance test results

  5. 05

    Drive Adoption and Improve

    We train users, monitor usage and performance, and use those insights to retire unused content and prioritize enhancements.

Use Cases

Reporting Solutions We Deliver

Examples of reporting and visualization work across functions.

Executive Performance Cockpit

A single dashboard shows revenue, margin, cash and customer KPIs against plan, with drill-down by region and product, replacing a manually prepared monthly slide deck.

Sales Pipeline and Quota Tracking

Sales leaders track pipeline coverage, win rates and forecast accuracy by team, with daily refresh from the CRM and alerts for at-risk deals.

Operational Control Tower

Reporting and Data Visualization FAQ

Which BI tool do you recommend?

We work with Power BI, Tableau, Looker, Qlik and others, and recommend based on your context. If you already use Microsoft 365 and Azure, Power BI and Fabric are often a natural fit. Looker suits teams that want a code-based semantic layer on BigQuery. Tableau remains strong for visual exploration. We consider existing licenses, skills, data platform, embedding needs and total cost, and we are equally comfortable improving the tool you already have.

What is a semantic layer and why does it matter?

A semantic layer is a governed model that sits between your data platform and reports. It defines tables, relationships, hierarchies, security and calculated measures such as revenue or churn once, in one place. Every report built on it uses the same logic, so numbers agree across dashboards and analysts. It also improves performance and makes self-service safer, because users build on certified definitions instead of writing their own calculations.

How long does it take to deliver a set of dashboards?

A focused dashboard suite, for example executive and sales reporting on a clean data source, can be delivered in four to eight weeks. If the semantic model and data pipelines need to be built first, plan for two to four months for the first release. We deliver iteratively, showing prototypes within the first weeks, so stakeholders can shape the design long before final sign-off.

How do you handle data security in reports?

We implement row-level security so users see only their region, entity, customers or team, and object-level security where certain columns or measures must be hidden. Security is defined in the semantic model, not in individual reports, which makes it consistent and auditable. We integrate with your identity provider, such as Microsoft Entra ID, and apply least-privilege principles for workspace and dataset access.

Can you fix our existing slow or unreliable reports?

Yes. We start with a performance and governance review that identifies the root causes, typically inefficient data models, complex calculations, unnecessary columns, missing aggregations or refresh bottlenecks. We then prioritize fixes by user impact. Many improvements, such as remodeling a dataset into a star schema or optimizing key measures, deliver significant speed gains without changing how the report looks to users.

How do you keep self-service BI from turning into chaos?

We combine clear structure with enablement. That means defined workspace tiers for personal, team and certified content, deployment pipelines for production reports, a certification process for shared datasets and usage monitoring to spot duplication. Alongside these guardrails we train analysts, publish design and modeling guidelines, and support a community of practice, so people know how to build good reports rather than simply being restricted.
