Can a Capability Maturity ModelHelp You?
n Is your company successful at learning from past mistakes?n Are you confident in your ability to deliver a product on time and
within budget?n Do you know if you’re spending your limited improvement
resources effectively?n Does everyone agree which problems within the organization
are the highest priority issues that need to be fixed first?n Are you successfully deploying organizational standard
processes, having gained quick acceptance from programpersonnel?
Unless you’re exceptional, your answer to most of the questions is “no”and a Capability Maturity Model can help you

n Include definition and description of theapplicable domain
n Provide a logical sequence for implementingstructured management
n Lead to better processes
n Allow you to prioritize process improvementefforts and measure their effectiveness
n Strong return on investment shown for CMMswhere historical data exists
Primary Benefits of Using AnyMaturity Model

SECM Return on Investment
n Insufficient data available with SECM toquote return-on-investment figures
– No pilot assessment performed to date– INCOSE evaluating becoming data repository for
SECM
n Correlation between SECM capabilitylevels and CMM for Software maturitylevels
– 5:1 Return on investment (SEI Report ‘95)
– 8:1 Return on investment (Motorola ‘98 report)» summary of financial benefits of CMMs can be found

How Can the SECM be Used?
n Guidance– develop documented or undocumented
processes
n Measurement– benchmark (TBD by INCOSE CAWG)– baseline an organization
– measure improvement
n Prioritization– prioritize initiatives using assessment data
and/or capability levels
n Risk Reduction– criteria in source selection
