How we can work with you

Team up with ITRex at any stage of your project, choosing the engagement model that fits best your project scope and business priorities.

We can build your product on the Time & Materials, Fixed Price, or Dedicated Team basis using agile or waterfall depending on your project specifics.

Software development methodologies

Having completed hundreds of successful projects, we will help you figure out what approach works best for the development of your software product, and assemble a powerful team to deliver the desired results.

Agile

Waterfall

The Agile approach centers around a continuously evolving project scope and iterative development where the team delivers a work product — a new feature or meaningful improvement — at the end of every iteration. This approach allows you to start quickly and make decisions in action based on instant feedback.

Agile is your go-to methodology when:

Your end-product vision is likely to evolve in the course of development

It’s difficult to detail all the requirements at the project onset, for instance, because of its complexity

The success of your product is strongly dependant on user feedback

It’s critical to direct the team’s energy straight off toward development, skipping a lengthy planning stage, to bring your product to market quickly

In the waterfall model, your entire project, including phases, tasks, and dependencies, is mapped out before development. This means thoroughly planning and documenting all processes, timelines, deliverables, resources, and costs beforehand. At the end of the day, you get less flexibility but a greater level of predictability.

The waterfall methodology is best when:

Your end vision and stakeholders’ needs are well defined and are not going to change

It is possible to fix all the requirements upfront

Your product requires multiple integrations with external systems, including in the process of development

You need to comply with more extensive project tracking or documentation requirements

Our engagement models

When selecting an optimum engagement model for our clients, we discuss a lot of details, from their primary business objective and project scope to the level of flexibility and control they require. Our aim is to come up with a solution that balances cost efficiency, performance, and flexibility best.

Time & Materials

Under the Time & Materials model, we can build your software product either in a linear sequence of stages or in increments through constant communication with you. You pay only for actual work done on daily or hourly rates per specialist.

This model is the right way to go when you don’t have precise software requirements and the exact project scope is hard to define or is likely to evolve

We develop your product in increments. You see the deliverables early and provide feedback, keeping the development process under control

You get regular reports from our project manager to track project budget and progress

Kickoff is then really fast: we define a high-level scope, agree on daily or hourly rates, and get started

Along the way, you can change anything, from the list of planned features to skill sets on the team, to align with changing market trends or business needs

You can measure product effectiveness early and pivot or suspend the project at any time, if needed, avoiding further expenses

Fixed Price

With this model, we build your software product for a price fixed upfront for the entire project. This often involves planning and estimating the entire project scope before development starts.

This model is mostly suitable for projects with a well-specified scope and clear requirements that aren’t going to change

All of us get a clear understanding of what exactly the end product and deliverables should be

This model requires little to zero involvement from your side after the requirements elicitation and planning stage

Together with your team, we begin with gathering requirements and planning thoroughly the project scope and time for product delivery

We agree on the total price of the project and start development based on the documented scope, reporting the progress regularly

During the development process, you may introduce changes but only through a formal change request process that will require amendments to the contract

Dedicated Team

Alternatively, you can simply hire our highly skilled engineers to fill in specific in-house skill gaps, or go for a full-fledged dedicated and self-managed team. You get professionals that integrate seamlessly into your environment, bring in a fresh angle and ideas, and deliver top results with in-house-like dedication.

This model is applicable when you need either extra engineering talent to boost your team or full-cycle services, from development to support

We offer a 30-day trial period for each specialist

You have full control over the team, budget and development process

We agree on a monthly cost per specialist or team at the beginning of the project

We can replace any team member based on your feedback or requirements update

You are free to scale the team up or down at any moment
