Design and Development
Application lifecycle management
We generate use cases, UML documentation, architect the system, create an object model, iteratively develop the system, unit and system test and modularize where necessary. These types of engagements are typically longterm and, almost always, incorporate a variety of software technologies.
If you are in need of expertise but only require the assistance of one or two engineers, the Hartmann Software Group can be of help. Instead of procuring talent by way of a placement agency who is likely to contact us, come to the Hartmann Software Group directly. You may realize some savings.
Mentor
The best way to learn is by doing.

The coaching program integrates our course instruction with hands on software development practices. By employing XP (Extreme Programming) techniques, we teach students as follows:

Configure and integrate the needed development tools

MOntitor each students progress and offer feedback, perspective and alternatives when needed.

Establish an Action plan to yield a set of deliverables in order to guarantee productive learning.

Establish an Commit to a deliverable time line.

Hold each student accountable to a standard that is comparable to that of an engineer/project manager with at least one year's experience in the field.

These coaching cycles typically last 2-4 weeks in duration.

Provide Expertise
Services for your business growth.
With the introduction of smart devices, e-marketplaces, electronic forms, SEO practices, big data, virtual office environments, media streaming and so much more, there is hardly a business whose livelihood is not, in some way, dependent upon the inclusion of such software functionality into its online presence, work environment and product offerings. Such inclusion often presents a complex array of challenges that are far beyond the expertise of the business as it demands an understanding of technological options, modular decomposition, backend systems integration and web services. Most importantly, the business requires IT talent and expertise; this is where the Hartmann Software Group shines. To that end, here is an overview of some of the services that we offer:
