IBM’s statements regarding its plans, directions, and intent are subject to change or withdrawal without notice at IBM’s sole discretion.

Information regarding potential future products is intended to outline our general product direction and it should not be relied on in making a purchasing decision.

The information mentioned regarding potential future products is not a commitment, promise,

or legal obligation to deliver any material, code or functionality. Information about potential

future products may not be incorporated into any contract. The development, release, and

timing of any future features or functionality described for our products remains at our sole discretion.

Performance is based on measurements and projections using standard IBM benchmarks in

a controlled environment. The actual throughput or performance that any user will

experience will vary depending upon many factors, including considerations such as the

amount of multiprogramming in the user’s job stream, the I/O configuration, the storage

configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve results similar to those stated here.

Rational Engineering Lifecycle Manager2



Continuous engineering is about game-changing capabilitiesExtending the Rational solution for Systems and Software Engineering

• Strategic Reuse“Don’t reinvent the wheel”

Strategic reuse across the engineering

lifecycle to increase design efficiencies,

engineer product lines, and tame complexity

• Continuous Verification“Measure twice, cut once”

Verify requirements and design at all stages

of the product lifecycle – to prevent rework and

achieve faster time to quality

• Unlocking Engineering Knowledge“Turn Insight into Outcomes”

Access, unlock and understand all engineering

information, regardless of source – to enable the

right decisions at the right times

Continuous engineering is an enterprise capability that helps to speed delivery of increasingly complex and connected products by helping engineers accelerate learning throughout the lifecycle, while managing cost, quality and risk.



Unlocking Continuous Engineering IBM Journey to Continuous Engineering

Linked Data

PLE



Open Services for Lifecycle Collaboration (OSLC)Working to standardize the way software lifecycle tools share data

� Open Community – @ open-services.net

� Driven by open-standards consortium

� Open specifications for numerous disciplines

� Including ALM, PLM, and DevOps

� Defined by scenarios

� Solution oriented

� Inspired by the web

� Open world assumption – vs. rigid APIs approach

� Linked-Data approach

� Internet Architecture

� HTTP based RESTful protocols

� Decouple data from container

� Unlock data from silo tools

� “Just enough” integration

� Consume/Provide the necessary services

Open Services for Lifecycle CollaborationLifecycle integration inspired by the web



Linked Data Approach to IntegrationPast Approaches to Integration

� Import/export workflow

� One super DB schema

� Always some tool/data “outside”

� Semantic loss

� Distributed internet architecture using standard internet technologies

� Uses “http” to link to resources

� Data is kept in native authoring tools

� Scale and incrementally add tools

Linked Data presents a fundamentally new approachIntegration and Collaboration across Engineering Disciplines



Product Versions and VariantsFacing the same Problem on multiple Variants, a sample scenario…

A problem is found and change

applied

Another important change in base

program

The PLE solution is addressed by adding capabilities to the platform tools and articulating best practices – rather than creating a new “PLE tool”

= Baseline

= Artifact propagation

� A Global Configuration is an hierarchical composition of multiple component configurations

� A Stream is an evolution of a (global) configuration over time, associated with a set of baselines

� Baselines record state in time and are immutable

� Streams are reusing common artifacts a use different version where there is variability

� Artifacts can propagate across streams

� Product variants are realized as streams

Introducing Rational Engineering Lifecycle ManagerExtending the Rational solution for Systems and Software Engineering

• Uses a Linked Data approach that

enables a single source of truth with a federated architecture to provide

Visibility – across many sources of data

Organization – information in context

Analysis - answer questions using that contextualized information

• Allows stakeholders to:

• manage growing complexity

• derive knowledge from the available data

• make timely and correct engineering and business decisions

Rational Engineering Lifecycle Manager (RELM)



Summary: Visualize, Organize and Analyze with RELMProvides visibility, impact analysis and document generation across the product lifecycle

A safety standard has changed - which

requirements, tests, design elements and

implementation artifacts are impacted?

A component is no longer available and needs to be replaced

with an alternative from another supplier. What

tests need to be re-run?

View Example: Visualizing the Impact of Change



View Example: Visualizing Cost Violations

Show me requirements that have implementation cost estimates greater than the

budget

Identify potential areas for weight

optimization across the

system



View Example: Suspect Links in the Engineering Lifecycle

I want to know the test cases that still

need analyzing after a set of requirement

changes

Things are changing rapidly.

Help me keep track!



View Example: Lifecycle Traceability for an ISO26262 Task

Give me the full traceability of task through the entire lifecycle to assess

compliance



View Example: DO-178B/C Compliance

Let me understsad “where we are” and

give me a quantitavive assessment

PLE Practices – Define Product Variant Workflow



� Create Variant task covers Planning stages for a new Product Variant

� Based on new Stakeholder requirements, a Product Line Manager creates and plans a new Product Variant

PLE Practices – Create Variant Task



� Tool mentors provide concrete guidance down at an application level

PLE Practices – RELM Tool Mentor for Create Variant Task



PLE Practices – Change Management Workflow



PLE Practices – Defect Management Workflow



What’s Next?



SummaryIBM Journey to Continous Engieering

� IBM has a clear Strategy to Continuous Engineering.

� Starting with Jazz, supporting OSLC, enabling

Linked Data and then Product Line Engineering, but the best is yet to come.

� Join us in this journey!
