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.
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.
Show more
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.
Show more
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.
Show more
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
