Confusion often arises because Microsoft has announced the retirement of several related cloud-based and web-based services. Here is the current status of the Microsoft Project ecosystem: 

Products Being Retired

  • Project Online: This service will officially retire on September 30, 2026. After this date, Project Online environments and data will no longer be accessible.
  • Project for the Web: Retired as a standalone brand and was fully merged into the new Microsoft Planner in 2024/2025.
  • Project/Roadmap Apps in Teams: These were retired in August 2025 and replaced by the unified Planner experience. 

Products Staying Active

  • Project Desktop (Project Professional/Standard): Not impacted by the cloud service retirements. You can still use it to manage .mpp files locally or connect it to alternative backend systems like Project Server SE.
  • Project Server Subscription Edition (SE): This on-premises/self-hosted version will remain supported through at least 2031. It is the recommended migration path for organizations that want to keep the “Project Web App” (PWA) interface without using the retired Project Online cloud service.
  • Microsoft Planner: Now serves as the primary cloud-based project management tool, absorbing the features of Project for the Web.

Agile Development History Timeline Overview

Agile’s history is a transition from rigid, manufacturing-based “Waterfall” models to flexible, people-centric frameworks. While the term was coined in 2001, its roots trace back to early 20th-century industrial practices and the “software crisis” of the 1960s. 

Early Foundations (Pre-1990s)

Before Agile became a formal software methodology, its core principles of efficiency and iteration emerged from manufacturing and early computing.

  • 1896: Sakichi Toyota introduced the “Stop and Notify” concept (Jidoka), a foundational Lean/Agile practice for immediate problem-solving.
  • 1948: The Toyota Production System (TPS) established Lean manufacturing and the Kanban system to manage workflow.
  • 1957: IBM began using incremental development on large software projects.
  • 1970: Winston Royce published “Managing the Development of Large Software Systems,” which formalized the Waterfall Model but actually cautioned against its rigidity.
  • 1986: Takeuchi and Nonaka published The New New Product Development Game, introducing the “rugby” metaphor for team-based development that inspired Scrum. 

The Rise of “Lightweight” Methods (1990–2000) 

Frustrated by Waterfall’s slow delivery, practitioners developed several “lightweight” frameworks. 

  • 1991: Rapid Application Development (RAD) popularized timeboxing and iterations.
  • 1993: Jeff Sutherland and his team first implemented Scrum at Easel Corporation.
  • 1994: The Dynamic Systems Development Method (DSDM) was created as a vendor-independent RAD framework.
  • 1995: Ken Schwaber and Jeff Sutherland formally co-presented Scrum at the OOPSLA conference.
  • 1996: Kent Beck introduced Extreme Programming (XP), emphasizing practices like pair programming and continuous testing.
  • 1997: Feature-Driven Development (FDD) and Crystal Clear emerged as alternative iterative models. 

Formalisation & Modern Evolution (2001–Present)

The movement unified under a single name and eventually scaled to entire enterprises. 

  • 2001: 17 software leaders met at Snowbird, Utah, to draft the Agile Manifesto, establishing four core values and 12 principles.
  • 2003: The book Lean Software Development by Mary and Tom Poppendieck officially bridged Lean manufacturing and software agility.
  • 2009: The concept of DevOps emerged, extending Agile principles into IT operations and deployment.
  • 2011: The Scaled Agile Framework (SAFe) was introduced to help large organizations manage multiple Agile teams.
  • 2012–2015: Agile surpassed the 50% mark in global adoption, becoming the industry standard for development.
  • 2020s: Agile principles are now widely applied outside of tech, in fields like marketing, education, and HR. 

Agile’s evolution is not just a 21st-century phenomenon but a response to decades of “software crises” and rigid industrial processes. Below is a comprehensive historical breakdown of Agile’s journey. 

1. Pre-Digital Foundations (1910s – 1940s)

Long before software, the concepts of efficiency and waste reduction were born in manufacturing. 

  • 1911: Scientific Management. Frederick Taylor encouraged managers to adopt worker suggestions for efficiency, opposing rigid habits.
  • 1940s: Lean Manufacturing (Toyota). Toyota pioneered the “Just-in-Time” method and Kaizen (continuous improvement) after observing American supermarkets.
  • 1948: Toyota Production System. Introduction of Kanban for visual workflow management. 

2. Early Iterative Development (1950s – 1970s)

The 1950s saw the first departures from strictly sequential “waterfall” planning. 

  • 1957: Incremental Development. IBM and Motorola teams, including Gerald Weinberg, used iterative methods indistinguishable from modern Extreme Programming (XP) for Project Mercury.
  • 1968: NATO Software Engineering Conference. Formally identified the “Software Crisis” (projects being late and over budget), sparking a search for better methodologies.
  • 1970: Waterfall Formalised (and Critiqued). Winston Royce described the Waterfall model but notably advocated for iterative releases to reduce risk. 

3. The Proliferation of “Lightweight” Methods (1980s – 1990s) 

Frustration with heavyweight, document-heavy processes led to several “Agile” precursors. 

  • 1986: “The New New Product Development Game.” Takeuchi and Nonaka published this HBR article, introducing the “Rugby” approach (teamwork over relay-race handoffs), which directly inspired Scrum.
  • 1991: Rapid Application Development (RAD). James Martin introduced RAD, emphasising fast prototyping and client feedback.
  • 1993–1995: The Birth of Scrum. Jeff Sutherland and Ken Schwaber formalised Scrum, presenting it at the OOPSLA ’95 conference.
  • 1996: Extreme Programming (XP). Kent Beck introduced XP at Chrysler, focusing on technical excellence through practices like Pair Programming and Test-Driven Development. 

4. The Agile Manifesto & Formalisation (2001 – 2010)

Agile moved from a collection of “lightweight” methods to a global standard. 

  • 2001: The Agile Manifesto. 17 developers met in Snowbird, Utah, to draft the Manifesto for Agile Software Development, establishing four core values and 12 principles.
  • 2003: Lean Software Development. Mary and Tom Poppendieck adapted Toyota’s Lean principles specifically for software engineering.
  • 2009: Software Craftsmanship. The Software Craftsmanship Manifesto emerged to refocus the community on the quality of the “craft” rather than just project management.
  • 2010: The First Scrum Guide. Published as the definitive resource on Scrum framework rules. 

5. Scaling and Modern Business Agility (2011 – Present) 

Agile expanded beyond coding into enterprise-wide strategy. 

  • 2011: Scaled Agile Framework (SAFe). Dean Leffingwell launched SAFe to help large corporations apply Agile at scale.
  • 2015–2017: Project Management Integration. Major bodies like AXELOS released PRINCE2 Agile, and the PMI introduced the Agile Certified Practitioner (ACP).
  • 2020s: Beyond Software. Agile principles are now standard in marketing, HR, and hardware development through concepts like Business Agility. 

HPE NonStop Tandem Programming Languages, a development timeline

HPE NonStop (formerly Tandem) has evolved through distinct architectural eras, each introducing specific programming languages and environments to maintain its legendary fault tolerance. 

1. The Tandem Stack Machine Era (1974–1990)

This era focused on the proprietary 16-bit stack-based architecture (TNS), where software was designed to “fail-fast” and operate in process pairs. 

  • Nov 1974: Tandem Computers founded by Jimmy Treybig.
  • May 1976: TAL (Transaction Application Language) launched with the first Tandem/16 (NonStop I) system. It was the only language available at launch, derived from HP 3000’s SPL.
  • Late 1970s: COBOL74, FORTRAN, and MUMPS were added to support business and scientific applications.
  • 1981: NonStop II introduced support for 32-bit addressing, enabling larger application memory.
  • 1983: SCOBOL (Screen COBOL) emerged alongside the Pathway transaction manager to handle terminal-based user interfaces and fault-tolerant logic.
  • 1986: NonStop SQL released as the first fault-tolerant relational database language.
  • 1987: C was introduced to the platform.
  • 1989: Integrity S2 line launched using MIPS processors, introducing a variant of Unix called NonStop UX. 

2. The MIPS RISC / Himalaya Era (1991–2004)

As Tandem migrated to MIPS processors (TNS/R), it introduced a Unix-like personality to attract modern developers while maintaining its legacy Guardian environment. 

  • 1991: Cyclone/R launched. Most software still ran in TNS stack mode using an “Accelerator” tool to translate code to MIPS instructions.
  • 1993: Himalaya K-Series released with native-mode compilers for C and COBOL to leverage MIPS performance.
  • 1994/1995: Open System Services (OSS) introduced a POSIX-compliant environment, enabling C++ and standard Unix utilities.
  • 1995: Java was first supported on the platform.
  • 1997: Compaq acquired Tandem; ServerNet became the standard interconnect.
  • Late 1990s: Support for scripting languages like Perl, Python, and PHP began appearing in the OSS environment.

3. The HP Integrity Itanium Era (2005–2013)

Following the HP merger, the architecture moved to Intel Itanium (TNS/E), branded as HP Integrity NonStop. 

  • 2005: NonStop i introduced. Compilers for C, C++, and Java were updated for the Itanium architecture.
  • 2000s: pTAL (Portable TAL) became the standard for system-level programming to bridge legacy TAL code to modern RISC/Itanium architectures.
  • 2011: Enhanced support for modern web languages and frameworks within the OSS environment. 

4. The Modern x86 / NonStop X Era (2014–Present)

HPE migrated the entire stack to standard Intel x86-64 processors (TNS/X) while retaining binary compatibility for legacy applications. 

  • 2014: NonStop X launched. All languages (COBOL, C, C++, Java) were migrated to target x86-64.
  • 2015: Transition to Hewlett Packard Enterprise (HPE) branding.
  • Recent Years: Integration of modern open-source dev-ops tools and languages, including JavaScript (Node.js), Python 3, Go, and Samba via the HPE NonStop OSS environment. 

HPE NonStop (formerly Tandem) programming has evolved from proprietary languages designed for fault-tolerant, transaction-oriented processing (TAL, COBOL85) to supporting open-source languages (Java, C++, Python, PHP) on modern x86-64 hardware. The ecosystem spans from the initial Guardian OS to modern J-series and L-series OS, supporting TNS, TNS/R, TNS/E, and TNS/X architectures. 

Key Programming Languages & OS Timeline

  • 1970s–1980s (Tandem Guardian): Core development centered on TAL (Transaction Application Language) (system programming), COBOL85 (business logic), and TACL (Tandem Advanced Command Language) (command shell scripting).
  • 1990s (Guardian 90 / NonStop UX): Introduction of C and C++ for more flexible application development, alongside Pascal and FORTRAN.
  • 2000s (H-Series / J-Series – Itanium): Shift towards Java and enhanced support for C/C++ in the Pathway server environment.
  • 2010s–Present (J-Series / L-Series – x86-64): Modern NonStop systems, particularly on x86-64, expanded to include scripting languages like Perl, PHP, and Python within the Open System Services (OSS) environment.
  • pTAL (Portable TAL): Introduced to bridge native TAL to newer, more portable processor architectures. 

Operating System & Architecture Evolution

  • Guardian (TNS): The foundational OS, relying on Tandem’s native stack, with TAL as the primary low-level language.
  • OSS (Open System Services): Introduced to bring POSIX-compliant, Unix-like functionality to NonStop, enabling easier porting of C/C++ and open-source applications.
  • Modern OS (J-series/L-series): Supports both Guardian (native) and OSS environments, allowing for a hybrid approach where traditional transaction processing (COBOL/TAL) mixes with modern web services (Java/Python).

TACL for HPE NonStop Tandem, Detailed Timeline

HPE NonStop Tandem TAL Detailed Timeline

TAL (Tandem Application Language) is the original system programming language for the HPE NonStop (formerly Tandem) platform. Developed by Tandem Computers in the mid-1970s, it was designed to provide high-level efficiency while allowing low-level machine access, similar to C but with a syntax influenced by ALGOL. 

Detailed Development Timeline

  • Mid-1970s: The Genesis
    • Tandem Computers, founded by James Treybig, introduces the first NonStop I system in 1976.
    • TAL is released as the primary language for writing the Guardian Operating System and system-level utilities.
    • The Tandem Advanced Command Language (TACL) is initially developed during this decade using TAL.
  • 1980s: Growth and Maturity
    • 1981–1983: Introduction of the NonStop II and TXP systems. TAL becomes the standard for developing mission-critical transaction applications like banking and point-of-sale systems.
    • 1985: The TAL Reference Manual is updated (March 1985), formalising advanced features like DEFINEs, LITERALs, and complex pointer arithmetic.
  • 1990s: Transition to RISC
    • Tandem introduces TNS/R (RISC) systems based on MIPS processors.
    • pTAL (Portable TAL) is introduced to allow TAL code to run “natively” on RISC hardware, offering better performance than the emulated TNS environment.
  • 2000s–Present: Modernisation and Maintenance
    • 2003–2005: HP (which acquired Compaq, who had bought Tandem) migrates NonStop to Intel Itanium (TNS/E) and later x86 architectures (TNS/X).
    • 2006: The Common Run-Time Environment (CRE) is enhanced to support mixed-language programs (C, COBOL, pTAL) seamlessly.
    • Current Status: TAL is considered a legacy language, with most new development occurring in C/C++ or Java. However, it remains vital for maintaining the core Guardian OS and legacy banking kernels. 

Typical Program Development Workflow

According to the TAL Programmer’s Guide, a developer follows this “timeline” to create a program:

  1. Source Code Creation: Writing statements, removing comments, and defining PROCs and SUBPROCs.
  2. Compilation: Running the TAL Compiler to generate an object file.
  3. Binding: Using the Binder Program to link the object file with the TALLIB Run-Time Library.
  4. Acceleration: Running the Accelerator (for TNS code) to optimise it for native hardware execution.
  5. Execution: Deploying via the TACL interface.

WordPress has evolved from a basic blogging tool in 2003 into a dominant Content Management System (CMS) that powers over 43% of the internet including this https://mark-whitfield.com website. Its history is defined by major version releases, often named after jazz musicians, and shifts toward “Full Site Editing”. 

This WordPress website started around 2021

The Early Years (2001–2005)
