Introducing the COTS Approach

What is the COTS Approach?

• Maximizing commercial off the shelf software in a GIS system

• System meets business goals by leveraging COTS- Configures and extends COTS- Avoids developing software

• Immediate capability… continually improving via COTS release cycles

• Users engaged early and often to iteratively improve system

Approaches to Building an Enterprise GIS

Comparing Approaches

COTS System follows standard system development lifecycles, but activities are different than traditional developmental systems

A Different Way of Thinking

• Challenges common procurement models- Requirements focused on business goals vice detailed

feature functions- Select COTS that best meets business goals and

implement “with the grain” for best results- Schedule linked to COTS release cycles

• Asks users to consider new business processes- New workflows based on COTS strengths (usually better)

- People resist change- Organizations resist change

• Avoid temptation to overly customize- Best intentions of many people often push systems

towards customization

Geodatabase Design

• Emphasize end-user capabilities- Define detailed information products- Build to deliver

• Embrace federated compilation and maintenance- Be realistic, prioritize compilation capabilities- Leverage data content provided by the enterprise- Integrate content at the service level, not RDBMS

• Design for COTS usability- Leverage geodatabase concepts (FCs, subtypes, etc)- Balance tradeoffs for maintenance and dissemination

Demos for Users

Planning

• Focus on business objectives and goals• What are you trying to accomplish?

- Improving productivity

- Increasing revenue

- Reducing cost

- Supporting regulatory requirements

• All system requirements and technical decisions should consider business goals

2

Remember you are trying to solve a business problem not engineer a new software module

Planning

• Plan project using multiple phases/iterations• Plan for heavy user interaction and validation of

capabilities• Allows for integrating new COTS releases• Provides an opportunity for intermittent training

2

Phases or iterations should focus on completing a use case or scenario

COTS Based Phased Planning

Continuous Learning & Improvement

Requirements

• Focus on the “what” NOT the “how”• Embrace the change – do not modify COTS

technology to support an inefficient process• Keep it simple

2

UsersCOTS Demos

Traditional COTS

Design

• Short focused interactive design sessions• Heavy use of prototyping and lab environment• End users along with COTS experts

- Defining user roles- Defining workflows- Identifying efficiencies- Understanding end user access

• Consider future COTS releases

2

Design should emphasize delivering immediate capabilities

COTS Design/Configuration Process

Develop

• Based on user input and feedback• Targeted to configuration not customization• 90% configuration 10% (or less) development

Implementation

• Understand you are changing process not just technology

• Leverage COTS training• Data flow patterns• IT Specifications• Security considerations • Administration

- Who? What? Skills?

• Don’t forget about the data!

Summary

Benefits of a COTS Approach

• Minimized cost to implement• Shorter schedule – immediate exercising by users• Reduced risk (technology proven by user-base)• Lowered maintenance costs• Evolves with future COTS functionality• Wider range of qualified people to use and maintain

system

Summary

• COTS configuration is a more efficient way to approach system development

• The COTS Approach redefines system development process, with focus on mission instead of building software

• ArcGIS 10 provides a platform for configuration and rapid development – making the COTS Approach viable for many systems
