ISSTECH — Innovative Smart Solutions

POWER BI & BUSINESS INTELLIGENCE CONSULTING

Connect your data to business decisions.

We assess SQL Server, Excel, Dynamics 365 and ERP data in the context of your business goals. From data preparation to secure report sharing, we help shape the design, development and operational requirements of your Power BI solution.

Discuss your reporting needs

DATA INTEGRATION

Bring different sources into a shared reporting approach.

We assess access options for data held in SQL Server, Excel, Dynamics 365 and other ERP systems. We consider suitable connectors, data entities, APIs or data transfer methods alongside access permissions, data volumes and freshness requirements.

Explore our Data Analytics and Enterprise Reporting solutions
  • Identifying data sources, ownership and access methods
  • Mapping shared customer, product and account fields across systems
  • Assessing Import or DirectQuery based on source support and business needs

POWER QUERY AND ETL

Traceable preparation steps for analysis-ready data.

We design extract, transform and load (ETL) steps using Power Query. We address data types, missing or invalid records, merges and appends to create repeatable preparation flows. Where supported, we assess query folding to push suitable transformations back to the data source.

  • Data cleansing rules and data quality checks
  • Maintainable query design using merges, appends and parameters
  • Reviewing source queries and query folding behaviour

DATA MODELLING

The right relationships for consistent analysis.

We use a star schema approach to organise fact tables representing business events alongside customer, product and date dimensions. We clarify table grain, relationships and filter directions to align the Power BI semantic model with reporting requirements.

  • Defining fact table grain and dimension keys
  • Assessing relationship cardinality and filter propagation
  • Reviewing unnecessary columns, high cardinality and model size

DAX AND KPIs

Clear performance measures grounded in business definitions.

We develop DAX measures around your organisation’s KPI definitions. We make filter context and calculation rules explicit, designing period comparisons, year-to-date totals and other time intelligence calculations with an appropriate date table.

  • Agreeing KPI definitions, calculation scope and acceptance criteria
  • Period analysis and time intelligence measures aligned with the date model
  • Reconciling measure results with source data and reviewing query performance

DASHBOARDS AND MANAGEMENT REPORTING

Report design that starts with the decision-maker’s question.

We design interactive report pages for executive summaries and detailed analysis. Filters, drill-through navigation and visual hierarchy are shaped around user needs. We assess Power BI Service dashboards for monitoring key indicators on a single canvas using tiles from reports.

  • Defining information needs for management and operational teams
  • Designing filtering, drill-through and mobile report layouts
  • Using Performance Analyzer to investigate visual, DAX and model bottlenecks

RLS AND DATA SECURITY

Align data visibility with user responsibilities.

Row-Level Security (RLS) restricts the rows users can see through role rules in the semantic model. We assess static rules or dynamic rules based on user identity against business requirements. RLS applies to workspace Viewers; it does not restrict Admin, Member or Contributor roles. Source access and workspace permissions are assessed separately.

  • Role definitions, user mappings and dynamic RLS rules where needed
  • Reviewing workspace roles alongside sharing permissions
  • Validating data access across user and role scenarios

POWER BI SERVICE

A reporting environment you can manage beyond publication.

We assess publishing and sharing requirements for workspaces, semantic models, reports and apps. For Import models, we plan scheduled refresh alongside source credentials, an on-premises data gateway where required, and refresh failure monitoring. Sharing and refresh options are considered against licensing and capacity requirements.

  • Workspace responsibilities and app-based distribution
  • Defining refresh frequency, gateway and source access requirements
  • Planning operational checks for refresh failures, usage and performance

PROJECT APPROACH

From business questions to reports people use.

We clarify scope with business teams and data owners, aligning data preparation, modelling and report development with shared acceptance criteria.

  1. Understand requirements and data

    We review decision processes, existing reports and data sources together to identify priority use cases.

  2. Design the model and reports

    We define data preparation, semantic models, KPIs and access rules, aligning report designs with user needs.

  3. Validate and put into use

    We test data and measure results, assess user feedback and plan publishing, refresh and knowledge transfer.
