Web Development Outsourcing: the Gist

Web development outsourcing allows businesses to hand over all or some development activities to a self-managed vendor while preserving the desired level of control over the web development project/projects.

  • Types of web development outsourcing: staff augmentation, dedicated team, full web development outsourcing.
  • A team for web development outsourcing: a project manager, a business analyst, a software architect, UX and UI designers, web developers, DevOps engineers, QA and testing specialists.

Web Development Plan

Below are described the typical steps we at ScienceSoft take to deliver corporate web applications and customer-facing solutions, web portals, ecommerce applications and SaaS products. The development plan can vary depending on the complexity of the future software, the required level of security, and more.

Step 1. Discovery

Duration: 20-30% of the project.

  • Getting a clear vision of major business needs (e.g., facilitate communication among employees, systemize corporate data, improve the brand’s image, attract new prospects).
  • Identifying the target users.
  • Drawing up high-level functional and technical requirements to web software.
  • Conducting a feasibility study. Creating a business case including NVP and ROI.

Step 2. Web application planning

  • Defining and prioritizing detailed web software functional and non-functional requirements.
  • Creating a software requirements specification (SRS).
  • Deciding on the architectural style (modular, monolithic, cloud-native, serverless, etc.) of new web software.

Here is a quick overview of common architecture types:

Monolithic architecture

Key benefit: Units are closely bound, making it is easy to test, debug and maintain software.

ScienceSoft recommends for: Simple software with few modules unlikely to be scaled.

Service-oriented architecture (SOA)

Key benefit: The enterprise service bus (ESB) serves as a point of touch between all services, so a damaged service won’t affect others.

ScienceSoft recommends for: Complex enterprise software with a priority on high reliability (healthcare, financial services, etc.).

Microservice architecture

Key benefit: Software components can be developed, tested and deployed simultaneously.

ScienceSoft recommends for: Complex systems with services built in different languages and likely to be scaled.

Cloud-based architecture

Key benefit: Decreases or removes a company’s dependence on the on-premises server, storage, and networking infrastructure.

ScienceSoft recommends for: Evolving mid-scale and large-scale projects.

Serverless architecture

Key benefit: Hosted by a FaaS provider, each function can be scaled automatically upon calls. Payment is charged only when a function is called.

ScienceSoft recommends for: Software with considerable traffic fluctuations, so there’s no need to pay for services during idle time.

  • Choosing the technology stack.
  • Drawing up an integration plan.
  • Planning the QA process:
    • Outlining the scope and types of testing (functional, performance, usability, compatibility, security, compliance).
    • Defining the testing schedule and a test team lineup.
    • Deciding on the ratio of automated and manual tests.

Lead Test Engineer and QA Consultant, ScienceSoft

We recommend using an optimal combination of automated and manual tests to achieve prompt verification of new builds in Agile projects with the embedded CI/CD process. We typically automate functional regression and integration tests, cross-browser testing, performance testing.

Step 3. Project planning

Duration: up to 5% of the project.

Note: Thoroughly performed discovery can significantly reduce project planning time.

  • Creating the software development project roadmap with major milestones, established timeframes and budget.
  • Setting KPIs to assess project health.

Sample KPIs:

  • Budget spent vs. budget planned.
  • Team velocity – to check the amount of work a team completes within one sprint.
  • Cycle time – to measure a time span needed for a team to complete a certain task on web development from the moment it was assigned.
  • Code churn – to assess web developers’ quality of work by monitoring lines of code added, adjusted or removed.
  • Release burndown – to evaluate how much of the web project scope is covered, added, left to complete, or overtaken within the current iteration.

Step 4. UX and UI design

Duration: 10-20 % of the project.

  • Researching wants and expectations of the target audience via focus groups by employing questionnaires or conducting interviews.
  • Building UX wireframes or mockups.
  • Working out GUI elements.

Step 5. Front-end and back-end development

Duration: 50-80% of the project.

  • Establishing development and delivery automation environments (CI/CD, container orchestration, etc.).
  • Writing server-side code and APIs.
  • Turning static user interface mockups provided by UI designers into the fully functional GUI.
  • Conducting unit tests.

Step 6. Quality assurance

Duration: up to 20% of the project.

  • Preparing the test environment and test data.
  • Creating test cases and combining them into test suites.
  • Setting up test management and defect tracking software.
  • (if needed) Developing test automation scripts and configuring test automation tools.
  • Running tests and reporting the results, sending the revealed issues to developers for fixing.
  • Retesting.

Note: Testing usually runs in parallel with development.

Step 7. Deployment, stabilization and preparation for maintenance

Duration: up to 10% of the project.

  • Deploying software in the production environment.
  • (often for enterprise web apps) On-site user training sessions.

Step 8. Web app support and maintenance

  • Selecting and configuring tools for continuous monitoring and testing of web app performance and availability.
  • Establishing support and maintenance activities for the new web app.

To ensure trouble-free operation of a new web application, ScienceSoft usually offers three support levels:

L1. User support team

– to provide software usage guidance and handle basic support cases (e.g., password reset, log in/log out) without an IT team’s involvement.

L2. Technical support team

– to fix software configuration, enhance its performance, resolve security issues without access to source code.

L3. Team of software engineers

– to fix software issues on the code and the database level.

Step 9. Further web app evolution in iterations

Note: An iteration typically lasts from 2 weeks to 3 months.

The development and delivery of new working software modules continue iteratively according to the following scheme.

Web Development Outsourcing Models

Depending on the scope of work that needs to be outsourced, you can consider three cooperation models:

Full web development outsourcing

When you outsource web app development, a vendor’s self-managed team is responsible for the complete development process. A vendor’s project manager sets and controls the team’s KPIs to ensure the results stated in SLA.

Check pros and cons


  • Access to top-notch talents with necessary competences.
  • Access to a vendor’s established web development processes.
  • Minimum management efforts on your side.
  • Guaranteed quality of web development project deliverables and timeline alignment (with penalties for breaching them).
  • Development infrastructure maintenance is on a vendor’s side.


  • The possibility of vendor lock-in.
  • The lengthy setup process (up to a month).


A dedicated team

A vendor’s team works on the outsourced part of the project, regularly reporting to your PM.

Check pros and cons


  • Preassembled teams that know how to work together.
  • Little/no guidance needed from your side.


  • Time-consuming collaboration setting between two teams.
  • Project team coordination, the concerns about quick and quality delivery, risk management are partially on your side.


Staff augmentation

Remote professionals join the in-house team, and you coordinate the whole project.

Check pros and cons


  • Precise number of team members is provided on your demand, from 0.5 FTE to 100+ FTE.
  • Easy resource scaling up and down.


  • Time-consuming adaptation of outsourced experts to the team and your working style.
  • Full team management is on your side, together with project-related risks.
