Application Life Cycle ManagementPractitioners Balance Multiple Perspectives

Are you changing the way you do ALM in response tochanges such as Cloud, Agile Development, SOA andAdvanced Integration?"

Key Issues

What is ALM and what kind oforganizations can benefit from it now?

How does ALM advance demand,requirement, quality and changemanagement practices and processes?

How will ALM alter the AD toolslandscape?

ALM delivers value by reducing the variability and thus therisk of software development, and maintenance activities.This benefits RUN, GROW and TRANSFORM initiatives thatdepend on the execution of software delivery projects.

ALM Adoption Hot Spots

Establish team memory, maintain

flow, "auditability;" drive iteration

mentality. Support process change

Agile

Virtual team collaboration,

consistency of artifacts, reduction

of communication delays,

Challenges stem from multi-

organization handoffs

Process enforcement, auditibility,

traceability

Geographically distributed

teams, Multisourcing

Complex (High-value,

high-risk) processes

Category Reason for Adoption

Complex Products Multiple sources of demand, multiple

delivery vehicles

Challenges in Clouds, Multisourcing andGlobally Distributed Development

Premium on Shared, Current Views- Scope, Requirements, Questions, Approvals, Issues

- Progress and State of Code, Tests, Resources

- Process Handoffs (Around the Clock or Stage Gate)

Not Just Custom Any More: Packages,SOA and Legacies

Packaged Applications- Proprietary Configurations, Transports

- Incomplete Team, Process Support

SOA- Registries/Repositories Are Distinctive Technologies

- Change Integration Incomplete

- Build and Deployment Challenges

Legacy

- Platform Support Fading

- Skills Issues

- Need to Supplement CM for Coordination

Where Do Improvements Show?

Reduction in defect cost

- Early Detection

- Key Improvement inRequirements Defects

Project Cycle Time

- 80/20 Rule

- Increased ConsistencyRelease Train

- Reduced time to market30% average

Metric Driven Insight

- Watch anomalies forproblems or improvements

- Avoid Hawthorne effect

- Correlated, not singledimension

Key Issues





17/24

Seismic Changes in Needs and Tools

Low-end version and configuration commoditize Teams select dev tools based on ALM function

Integrations to ITSM become more important

Requirements Management and Test Management moveout of specialized tooling to ALM

Agile and Waterfall hybridize

Status, time reporting and work breakdown are done in

ALM instead of PPM.

Hosted Offerings allow ALM in the Cloud.

Development, Test activities done in the Cloud.


18/24

ALM is a Misnomer

Requirements

Dev to Deploy

Life cycle doesnt begin with

requirements and end with build

21/24

Product Strategies to Gain Traction inEmerging ALM Markets

IBM and Microsoft leverage breadth and controlof the developer desktop

SCCM, PPM and test vendors leverage theirinstall bases

Specialists focus on scaling agileimplementations


22/24

Challenges and Benefits

Challenges of the New Normal Smaller units of change, but more frequent

Reuse spreads the impact of changes more broadly

Larger and more diverse groups of people able to make changes(rise of the citizen developer)

Quality risks from reduced skills

Benefits of ALM and Composite IT Planning and Control

Enables better toleration of change (evolution-friendly)

Enables rapid assembly of new applications to support new

processes and meet new requirements (greater agility) Fosters reuse of code and components (improves developer

productivity)

Reduces skill requirements for creating new applicationfunctionality (potentially reducing the IT backlog)


23/24

Recommendations

This Year- ALM is a tactical deployment

- Leverage in current hot spots

Agile, Geographic Distributed, Complex Process, Complex

Product

- Prepare for spread to trouble areas

Packages, SOA, Legacy

Three to Five Years

- Broader Coordination of ALM, PPM, ITCM

- Strategic Suppliers Emerge, Consolidate
