User Interface

We build mobile apps, web solutions, and visual interfaces for devices with an eye towards a rewarding and productive user experience. To achieve these goals, we incorporate such essential system properties as clarity, intuitiveness, interactivity, and responsiveness.

• PABM has a dedicated department of 20+ usability experts including business analysts, consultants, information architects, and visual designers, who are able to get a 360-degree view of your project and apply the appropriate tools and methods to ensure a clear layout, intuitive usage, transparent navigation, and high interactivity.
• PABM utilizes user-centric, business objectives based approach to UI design. We choose the right focus for different types of solutions and their modules.

PABM UI Design Principles

PABM highlights and unites the core principles of a highly usable solution, and applies them practically in UI:

Effectiveness & Visibility — each user’s action should produce a result. Effective UI increases customer satisfaction and employee productivity, so we carefully treat both frontend and backend usability. PABM adds maximum visibility to objects, so that users can easily identify the function and take a correct action spending minimum time to accomplish a task.
Performance — in addition to careful software architecture design which is vital to the application performance, our experts tune the application interface for quick response by implementing RIA technologies and features.
Consistency and Predictability — once a function is learnt users reasonably anticipate that the next time it will behave identically. We ensure that the similar looking functionality produces similar results throughout the entire application.


We utilize a highly transparent iterative approach that allows achieving better usability results and increasing application productivity.
The following 4 phases describe how we handle UI design tasks within the development process:

Requirements and Conceptual Design

PABM delivers user-centered UI design paying great attention to the analysis of use cases and business scenarios, highlighting target user groups and identification of critical success factors. UI Requirement At this stage PABM develops data models, entity relationship schemes and workflow diagrams to eliminate possible vision gaps and serve as guidelines for further project stages.

UI Prototyping

Depending on the business goals, functional scope and complexity level of the project PABM delivers a number of prototype artifacts:
• Static Mockups

• Clickable Wireframes

• Fully Designed Prototype

The professional software prototyping is also available at PABM as a separate service.


Technology Factor

Actual interface implementation depends strongly on the chosen technologies, so PABM strives to cut project costs by utilizing best-practices for the particular technology and get maximum technology benefits / comply with restrictions at the earlier conceptual and prototyping phases.

Usability and UI Testing

The PABM QA team executes business scenarios and use cases to detect interface issues or inconsistencies that distract and mislead users from arriving at their goals. PABM utilizes several testing methodologies and options in order to minimize possible issues at the earliest project stages, enable quick response to changes and organic refinery.
• Prototype Testing • Iterative Testing
• Acceptance testing. The professional software testing is also available at PABM as a separate service.

Visual Design

Visual Design
In most cases (for some types of web apps UI has a very minor importance or even doesn’t require UI at all) visual design is an integral part of web application development project. PABM always keeps in mind that visual design is a vital tool to increase usability by fastening interface learning, memorability and consistency, and provide additional value to the application making its usage enjoyable. The PABM graphic design team works in close collaboration with analysts and usability testers, providing high quality results. All the layouts, forms and their elements and controls produced by PABM designers are tailored to easy HTML slicing, thus avoiding expensive efforts for implementing visuals to the application engine.

User Experience

We develop applications in compliance with the Human Interface Guidelines which outline the visual design principles, consistency of the access to and behavior of common elements of the interface across major OS and desktop environments. Taking special care of the following aspects in an interface facilitates more intuitive, learnable, and optimal user experience:
• Workflow/user journey modeling, intuitive navigation — help define the essential interface elements that would enable a user to successfully accomplish required tasks.
• Clean highly interactive layouts — provide for dynamic data and content delivery and transformation.
User Experience
• Highly interactive controls/widgets — from buttons to interactive grids — enable a dialog between a user and a program, providing a single interaction point for direct manipulation of the data processed by the application.
• Data visualization — interactive charts and info graphics — transformation and adaptation of the available data to a more convenient form of presentation.
