The new Gartner Critical Capabilities report explains how APIs and microservices enable digital leaders to deliver better B2B, open banking and mobile projects.

Introduction

In the 21st century, the merger between Product Lifecycle Management (PLM) and Application Lifecycle Management (ALM) is perhaps the most successful of all engineering practices. The invention of complex systems like the Large Hadron Collider, are the symbols of successful integration between hardware and software systems.

In short, the convergence of PLM and ALM is essential when developing a system with both hardware and software components.

What Is PLM?

PLM is an approach that was conceived in the year 1985 by the American Motors Corporation (AMC), to build hardware products with or without software components. Across the product lifecycle, PLM is the business solution that encourages collaborative creation, management, dissemination, and use of product defined information spanning throughout the extended enterprise.

PLM aims to manage the product lifecycle right from its inception to engineering design, development, and manufacturing. PLM includes engineering CAD and provides a framework to help connect, organize, control, manage, track, consolidate all product-centric information. Adopting the PLM process has proven to be effective in data monitoring, especially in Aeronautics and Defense besides the automotive industry.

However inclusive the entire PLM cycle maybe, the way in which software projects grew in complexity and volume have necessitated the need to have a separate set of practices for the same. The reason being, the nature of artifacts that are used in software development are empirically different from the ones used in PLM. Software development shifts focus from primary PLM artifacts like EBOM, MBOM and stress more on the secondary PLM artifacts like Requirements, Documents, Embedded software and Test Cases to name a few.

The umbrella term that encompasses all the activities, methods, and processes used in Software Development is the Application Lifecycle Management or ALM.

What Is ALM?

Developing a new Software can be quite complex. It consists of Business Requirements, Functional Requirements, Defects, Tasks, and Resources including the need for integration with different legacy applications.

ALM aims to manage the three prime aspects of software lifecycle – Governance, Development, and Management.

Requirements Management, Code Development, Testing, and Release of a software product are distinctly different from that of a hardware product, hence are addressed by ALM.

Like PLM, ALM addresses activities from the inception of an idea till the final deployment and dissolution of a software application. ALM has various SDLC (Software Development Lifecycle) methodologies that are used in a standalone or hybrid form.

Differences Between PLM and ALM

Sl. No.

ALM

PLM

1

ALM deals with intangible and intellectual properties like Requirements, User Stories, Sprints, Test Cases, Issues/Bugs, etc.

PLM is more definitive in term of its implementation. It deals with managing tangible hardware components like Drawings, Material, Cost, Workers, Tools and Subsidiary Parts.

2

ALM’s core building blocks include a set of requirements, code files, test cases, defects, and released application code.

PLM on the other hand, comprises of different types of hardware or parts bound by ’Part of Relationship’ and more and more recently the electronic hardware with embedded software that defines most modern systems – be they automotive or defense or industrial.

3

ALM focuses on the effectiveness and efficiency of delivering working components

PLM’s focus encompasses objects ranging from the complete bill of materials till the product configuration in the chain.

4

In ALM, a broad level concept or a requirement is decomposed using diagrams such as Entity Object, UML Diagrams, and Flowcharts, etc.

Products in PLM process follow the ’Part of relationship’ decomposition and get categorized under sub items such as Electric Layout, Transmission System, Interior design layout, etc.

Need for ALM and PLM Integrations

The holistic nature of modern products and their connectivity necessitate a new approach to their development. Traditionally, product innovation and manufacturing follow separate development streams for hardware and software. These development streams progress in complete or partial isolation.

With the exponentially growing volume of embedded codes in hardware devices, complexity increases by leaps and bounces. Sticking to the old method of sequential development is no longer feasible. This makes widespread adoption of agile methodologies a preferable choice for speeding up a software development process.

Integration of distinct development streams of hardware engineering and manufacturing, software development, and service innovation, therefore, became a necessity. The previously separate lifecycles were increasingly interconnected, and managing them required a new approach.

Here’s a look at some the real-life problems:

  • IoT is perhaps the foremost achievement of PLM and ALM Integration, where hardware products like Refrigerators, ACs, and Heating Systems have been made smarter by acting like nodes in the integrated web of things. Data from this internet of things can be managed with popular software that harness data to make our lives comfortable.
  • Popular gaming consoles like Microsoft Xbox and Sony PlayStation can be termed as yet another milestone for PLM and ALM Integration. A sound PLM Process has led to sleek hardware that seamlessly interfaces with multiple power sources, output devices like television, tablets and mobile phones and supported by a wide variety of ports. Further, software utilities like Unity, OpenGL, Corona, etc., built through an equally competent ALM process support this advanced hardware creating amazing end-user experiences.
  • Utility applications are now focusing not just on cross-platform operations but also cross devices. Applications like Salesforce, Service Now, and Amazon’s Kindle are all trying to integrate the PLM and ALM processes with the object of scaling to multiple heterogeneous devices.

Different Phases of ALM & PLM:

Alm PLM

  • Requirements Management
  • OA and Test Management
  • Demand Management
  • Change and Configuration Management
  • Build and Release Management
  • Variant Management
  • Audits, Metrics, and Reporting
  • DevOps
  • BOM Management
  • Computer-aided design (CAD)
  • Collaboration
  • Change Management
  • Document Management
  • System Engineering and Development
  • Compliance

Conclusion

The integration between PLM and ALM can either be carried out on a point-to-point basis between a pair of tools or it can be done using an ESB model, which becomes more scalable compared to the former.
