WHAT YOU NEED TO KNOW

Frequently asked questions about Digital

1.
How much does it cost to build a new application or digital platform?

The cost depends on the scope of the project and is determined on a case-by-case basis. Key factors include the number and complexity of features, integration with existing systems, security requirements, and the overall scale of the solution. Sii helps clients define business priorities and establish a clear delivery plan, providing greater visibility into costs and control over the budget throughout the project.

2.
How long does it take to design and launch a digital solution?

The timeline depends on the scope and complexity of the project. Smaller solutions can often be delivered within a few months, while larger, more complex platforms require longer delivery timelines. Sii works iteratively, allowing clients to access initial functionality sooner, gather feedback, and validate the product direction as development progresses.

3.
Can you take over and complete a project started by another vendor?

Yes. Sii can take over a project previously handled by another technology partner. The process begins with an assessment of the codebase, architecture, documentation, and current project status. This helps identify potential risks, technical debt, dependencies, and areas for improvement before defining a plan to stabilize the solution and continue its development.

4.
What does the delivery process look like, and how much involvement will you need from my team?

Client involvement is typically most important when defining business objectives, making key decisions, and validating outcomes. Sii manages the delivery process across requirements analysis, design, development, testing, and deployment. Regular communication and joint progress reviews support timely decision-making, maintain alignment, and reduce the risk of misunderstandings.

5.
What are the most common risks in digital projects, and how do you help mitigate them?

Common risks include unclear requirements, evolving business needs, and integration challenges. Sii helps mitigate these risks through regular workshops, iterative delivery, continuous quality assurance, and transparent progress reporting. This approach helps identify issues early and address them before they affect the project timeline or budget.

6.
Can the new solution integrate with our CRM, ERP, and other existing systems?

Yes. Sii designs solutions to integrate with the client’s existing technology environment. Our teams assess current systems, available APIs, and business requirements to enable reliable, efficient data exchange. This allows new solutions to support existing processes without the cost and disruption of replacing systems that are already in place.

7.
How do you ensure data security and compliance with regulations such as the General Data Protection Regulation (GDPR)?

Security is built into the solution from the outset. Sii applies established practices for access management, data protection, system monitoring, and security testing. Regulatory requirements, including GDPR, are also considered during the design phase to reduce the risk of non-compliance and security incidents.

8.
What happens after go-live? Do you provide ongoing development, maintenance, and technical support?

Yes. Sii provides ongoing support after go-live. Services can include application maintenance, bug fixes, monitoring, security updates, and continuous feature development. This allows clients to focus on their core business while their solutions continue to evolve in line with changing business and technology needs.
