DLM is a vital, often under-implemented, part of

any ALM or DevOps solution.

SDLC

Software Development Life Cycle is a splitting of software development work

into distinct phases (or stages) containing activities with the intent of better

planning and management. It is often considered a subset of the The systems

development life cycle. The methodology may include the pre-definition of

specific deliverables and artifacts that are created and completed by a project

team (SDLC), also referred to develop or maintain an as the application.

Common methodologies include waterfall development life-

cycle, prototyping is a term used in systems engineering, iterative information

systems and incremental development software engineering to describe a

process for planning, spiral development creating, rapid application

development testing, extreme programming and various types of agile

methodology. Some people consider a deploying an information system.[1] The

systems development life-cycle "model" a more general term for concept

applies to a category range of methodologies hardware and a software

development "process" a more specific term to refer to a specific process

chosen by configurations, as a specific organization. For examplesystem can

be composed of hardware only, there are many specific software

development processes that fit the spiral life-cycle model only, or a

combination of both. 5

PLM

In industry, product lifecycle management (PLM) is the process of managing the entire lifecycle of a product from inception, through engineering design and manufacture, to service and disposal of manufactured products. PLM integrates people, data, processes and business systems and provides a product information backbone for companies and their extended enterprise.

ALM

ALM is a set of pre-defined processes that

start somewhere in the business as an idea,

a need, a challenge or a risk and then pass

through different development phases such

as Requirements definition, design,

development, testing, deployment, release

and maintenance spanning across an entire

lifecycle of a product. Throughout the ALM

process, each of these steps is closely

monitored and controlled, followed by

proper tracking and documentation of any

changes to the application.7

Things

Create & IterateMake that business idea a reality, but don’t stop there, all ideas evolve over time and need more development

Devise & StrategizeDevise a business plan, monitor the application through Project & Portfolio Management

Monitor & RespondUtilize test group & user feedback to prioritize bugs, enhancements and future versions. Respond quickly to issues

Aspects of ALM

Things

Develop a business case

Manage development with Project Portfolio Management

Upon deployment, continue to manage the application like any other business asset with Application Portfolio Management until End of Life

Occurs throughout the entire ALM process

Governance

Things

Define requirements based on business case(s)

Design, develop and test the application

Manage maintenance of the deployed application

Rinse and repeat for each iteration of the application until End of Life using SDLC

Fundamental part of every Application Lifecycle

Development

Things

Ramps up quickly near the end of the first development cycle

Continues until application End of Life

Can easily be expanded and adapted to a more proactive monitoring approach

Continuous deployment, monitoring and feedback

Homegrown software development processes in place

Software development best practices more commonly accepted

Development practices are highly innovative

Most often limited by technology or lack of tooling

Tools not fully integrated into development environment

Tools are fully integrated into the development environment

ALM Maturity

ALM Maturity Model

Basic: Homegrown processes; typically not documented

Standard: More process uniformity, but not 100%

Advanced: Processes across the organization and clearly documentedMost companies strive for, and land here

Dynamic: Rare, not feasible for most companies to achieve this level

DevOpsAgile ALM

DevOps

DevOps (combined development and operations) is a culture, movement or practice that emphasizes the collaboration and communication of both software developers and other information-technology (IT) professionals, while automating the process of software delivery and infrastructure changes. It aims at establishing a culture and environment where building, testing, and releasing software can happen rapidly, frequently, and more reliably

Database Lifecycle ManagementRedgate DLM Automation Suite and Monitoring

DLM

Database Lifecycle Management combines a business and technical approach to improving database development, delivery and management.

The scope of DLM is, as with ALM, the entire useful life of a database, including aspects of design and data architecture, encompassing the database development and delivery processes, and through to managing and refining the database while it is in operation. It is intended to make all the processes that make up the lifecycle more predictable and visible, with the objective of reducing costs and increasing quality. It also aims to encourage innovation, and cooperation between teams.
