Mobile Architecture
13
Architecture Constraints
14
• Limited: battery life, bandwidth, memory, storage
• Large data sets: paging, parsing, filtering
• Support native runtime features (graphics, camera, GPS)
• Rich user experience over slow data connections
• Connectionless environments• Security and transactional state
regardless of connection • Context awareness and digital memory • All-ways-on: Agents, events and rules,
RFID, sensors and actuators
Pervasive computing is coming. How will your architecture support it?

Mobility Roadmap
31
Perficient’s Mobility Roadmap
32
Perficient’s mobility roadmap defines mobility efforts in the context of a program that meets business goals. The roadmap will also defined activities needed to create a consistent user experience, comprehensive architecture and standardized application development practices.
The roadmap will include activities to addressing the following needs:
• Business vision and goals • User experience and branding • Application integration architecture • Development approach and lifecycle • Organizational suture and governance needs • Development tools and framework needs• Define Quick-win Pilot Project • Program timeline, budget, iterations
Mobility Application Roadmap
33
Business goals for mobility drive the mobile application portfolio development and the requirements for the portfolio drive architecture decisions.
• Define each mobile application based on business goals • Understand components needed for each mobile application• Learn the audience and key scenarios where mobile applications will be
used• Define the design considerations for mobile applications – user
experience and architecture requirements • Identify specific scenarios for mobile applications, such as security,
deployment, power usage, integration and synchronization• Define the key patterns and technology considerations for designing
mobile applications• Determine high-level project estimates, timelines, and benefits • Develop program roadmap and architecture vision to support the to-be
mobile portfolio
Mobility Roadmap Deliverables
34
While each of our customers needs are unique and as such our roadmaps are customized the following deliverables a typical for mobile roadmaps:
• Documented business goals and critical success factors • Recommended organizational model and governance frameworks • Platform architecture recommendations and implementation timelines • Experience design strategy • High-level as-is and to-be architecture to support mobile • Experience design, architecture and development of a pilot mobile
application • Plans to mature people, processes and technology driven by business
needs and project requirements • Candidate mobile applications with high-level costs and benefits; typical
mobile candidate projects include: • Marketing and customer loyalty • Customer and employee self service • Content distribution – knowledge management, marketing, process documentation • Business process tasks notifications and approvals • Work order and field service automation • Inventory management • Logistics optimization • Messaging and alert notification
Sample Roadmap
35
Mobility Roadmap Timelines and Staffing
36
The investment in a mobile roadmap varies with the detail of candidate application discovery and estimation; the complexity of pilot project and the implementation of mobile platforms to support the pilot. Roadmaps, architecture, frameworks and organization skills are developed over time and the roadmap is a living document and ongoing process.
The following are options for the development of the mobility roadmap:
• Mobility current-state assessment and recommended action items • 2 Weeks • XD Architect and Mobility Architect
• Mobility roadmap and pilot project • 3-5 Weeks • XD Architect, Mobility Architect, Mobile Developer
• Mobility Standards, Architecture and Frameworks • 5-6 Weeks • XD Architect, Mobility Architect • If done with a pilot project add Mobile Developer
