Leigh Cotton Mill Heritage – Overview and Chronological Timeline

Leigh’s cotton mill heritage represents the peak and final generation of the Lancashire textile empire. Originally a dairy farming and domestic weaving town, Leigh evolved rapidly into a highly specialised fine-cotton spinning powerhouse, capitalising on local coal measures and the Bridgewater Canal.

Unlike older mill towns that grew haphazardly, Leigh’s industry peaked late, culminating in massive 20th-century “double mills” like the iconic Grade II listed Leigh Spinners Mill*. Today, these red-brick giants have transitioned from empty eyesores into thriving community hubs, arts centers, and commercial business parks.

Detailed Timeline Breakdown by Era

1. The Pre-Industrial & Domestic Era (Pre-1830)

Before massive brick factories dominated the skyline, textile production was a distributed, domestic industry.

  • 1740s–1770s: Local weavers produce “fustians” (coarse cotton-linen fabrics) in their own homes. The invention of the fly shuttle and Richard Arkwright’s water frame begins to shift production from homes to early water-powered mills.
  • 1800s–1820s: The local economy relies heavily on agriculture, domestic handloom spinning, and a flourishing silk weaving trade.

2. The Early Factory & Industrialisation Era (1830–1879)

The introduction of rotative steam engines allowing mills to move away from rivers, combined with cheap local coal, sparks Leigh’s factory revolution.

  • 1830s: The first dedicated steam-powered cotton mills are constructed in Leigh.
  • 1839: The “Leigh Fight” (14 August). Amid massive unemployment and Chartism protests, a mob of 2,000 workers threatens to burn down Hayes Mill. The Riot Act is read, leading to violent clashes with troops.
  • 1858: Construction begins on the multi-storey mill on Kirkhall Lane (later known as Pennington Spinning Company).
  • 1861–1865: The Lancashire Cotton Famine. The American Civil War blockades southern US ports. Raw cotton supplies dry up, causing widespread starvation and temporary mill closures across Leigh.
  • 1862: F.W. Bouth founds Bouth’s Mill. []
  • 1870s: The local silk industry collapses due to foreign competition; multi-storey silk factories like Rose Mill and Welch Mill are rapidly converted to cotton weaving.
  • 1875: The local townships of Pennington, Westleigh, and Bedford officially merge to form the Leigh Local Board District.

3. The Boom & “Super-Mill” Era (1880–1925)

Leigh enters its golden economic age, specialising in fine-mule cotton spinning and building architectural “super-mills”.

  • 1880s: Major industrial development concentrates along the banks of the Bridgewater Canal, including the construction of the landmark Mather Lane Mill.
  • 1899: Leigh is officially incorporated as a Municipal Borough, reflecting its vast commercial wealth.
  • 1905: The Butts Spinning Company constructs Butts Mill.
  • 1911: The industry reaches its employment peak. Over 6,000 people are directly employed in Leigh’s textile sector.
  • 1913: Entrepreneurs John Horrocks and Edward Crowther found Leigh Spinners Mill. Designed by architects Bradshaw, Gass & Hope, “Mill 1” (East Section) opens alongside its boiler house and landmark chimney stack.
  • 1914–1918: Outbreak of World War I halts the export markets and severely disrupts further building expansions.
  • 1923–1925: Construction resumes post-war. “Mill 2” (West Section) is completed, making Leigh Spinners one of the most complete double mill complexes in the United Kingdom.

4. The Slump, War, & Industrial Decline (1926–1999)

Global competition, lack of technical modernization, and shifting markets trigger a long, irreversible contraction.

  • 1920s–1930s: The Great Depression triggers massive closures. Despite slumps, cotton still provides about 14% of all local employment (approx. 6,000 jobs). Pennington Mill shuts its doors in 1930.
  • 1939–1945: World War II temporarily shifts mill focus to industrial war fabrics, and some empty sheds are utilised as prisoner-of-war camps.
  • 1950s–1960s: Post-war decline accelerates. Butts Mill ceases spinning operations entirely in 1960. Across Lancashire, mills close at a catastrophic rate of one per week.
  • 1969: Facing the total collapse of the cotton thread trade, Leigh Spinners Ltd structurally shifts its business model from cotton yarn spinning to carpet manufacturing.

5. Dereliction & Modern Regeneration (2000–Present)

The 21st century sees a major pivot toward preserving architectural heritage via community asset conversion.

  • 2012: Leigh Spinners expands its manufacturing footprint to produce modern synthetic turf products for sports and landscaping.
  • 2013: The Leigh Building Preservation Trust (LBPT) is formed to save the decaying sections of the mill and its rare Yates & Thom cross-compound steam engine. They secure a vital £75,000 restoration grant.
  • 2018: Volunteers successfully turn the historic mill steam engine for the first time in decades. Roof repairs begin on Mill 2.
  • 2020s: Rapid floor-by-floor expansion transforms the site into a massive dynamic space.
  • Present Day: Leigh Spinners Mill functions as a premier heritage centre. It hosts more than 60 local tenants, featuring sports gyms, art studios, an independent cinema, a computer museum, and community facilities.

Columbo Overview and Detailed Timeline by year

Columbo is one of television’s most celebrated crime dramas, spanning 35 years, 69 episodes, and two major television networks. Starring Peter Falk in his four-time Emmy-winning role, the show completely upended standard detective tropes with its signature “inverted detective story” structure.

Columbo Peter Falk
Peter Falk, Columbo

The following guide breaks down the core characteristics of the series, followed by a comprehensive, year-by-year chronological timeline of its production and broadcasting history.

Detailed Description of the Series

The Inverted “Whodunit” (The Howcatchem)

Unlike standard mystery shows where the audience tries to guess the killer, Columbo is an inverted detective story. Every episode begins by showing the audience exactly who the murderer is, their motive, and the elaborate steps they take to craft an “airtight” alibi. The true tension and entertainment lie in the psychological cat-and-mouse game between the killer and Lieutenant Columbo, watching him slowly pick apart their flawless crime.

The Character of Lieutenant Columbo

  • The Appearance: Columbo is famously dishevelled. He wears a rumpled, beige raincoat over a wrinkled suit, drives a battered 1959 Peugeot 403 convertible, and frequently chomps on a half-burned cigar.
  • The Tactics: He acts incredibly humble, forgetful, and easily distracted. This is a deliberate ploy to make the high-society killers underestimate him, causing them to let their guard down and talk too much.
  • The Catchphrase: Just as a suspect believes Columbo is leaving and they have gotten away with murder, he stops, turns around, scratches his head, and delivers his iconic phrase: “Just one more thing…”
  • Personal Quirks: He works for the Los Angeles Police Department (LAPD), never carries a gun, loves chili with crackers, owns an incredibly lazy basset hound simply named “Dog”, and constantly references his unseen wife, Mrs. Columbo.

Detailed Production & Broadcast Timeline

The history of Columbo spans across two distinct network eras: the NBC Era (the original 1970s run) and the ABC Era (the late 1980s revival through to the final specials).

Pre-Falk Origins (1960 – 1962)

  • 1960: Writers Richard Levinson and William Link introduce the character of “Lieutenant Columbo” in an episode of the anthology series The Chevy Mystery Show titled “Enough Rope”, played by actor Bert Freed.
  • 1962: The writers adapt the story into a stage play named Prescription: Murder, where Columbo is portrayed by Oscar-winner Thomas Mitchell.

The NBC Series Era (1971 – 1978)

During this run, Columbo does not air weekly. Instead, it serves as a rotating program on The NBC Mystery Movie alongside shows like McCloud and McMillan & Wife.

  • 1971: Season 1 begins. The official premiere episode, “Murder by the Book”, is directed by a young, pre-fame Steven Spielberg.
  • 1972: Season 1 concludes, and Season 2 premieres in September. This season includes classics like “Etude in Black”.
  • 1973: Season 2 ends, and Season 3 launches, introducing “Any Old Port in a Storm”, which features Donald Pleasence and is widely considered one of the best episodes of the series.
  • 1974: Season 3 wraps up, and Season 4 premieres. It features Johnny Cash in “Swan Song” and Dick Van Dyke in “Negative Reaction”.
  • 1975: Season 4 concludes, and Season 5 debuts in the autumn, featuring the episode “Forgotten Lady”.
  • 1976: Season 5 ends. Season 6 premieres in October with a shortened, three-episode order as Peter Falk begins negotiating fiercely over his contract and salary.
  • 1977: Season 6 wraps up. Season 7 launches in November, highlighting the fan-favourite episode “Try and Catch Me” starring Ruth Gordon.
  • 1978: The final NBC episode, “The Conspirators”, airs in May. Burnt out by the rigorous schedule and wanting to pursue feature films, Peter Falk walks away from the character, ending the original run.

The Hiatus & Spin-Off (1979 – 1988)

  • 1979: NBC attempts to keep the brand alive without Falk by launching a spin-off series, Mrs. Columbo, starring Kate Mulgrew. It is heavily rejected by fans and swiftly cancelled.
  • 1980–1988: Columbo remains entirely dark for nearly a decade.

The ABC Revival Era (1989 – 2003)

ABC successfully strikes a deal with Peter Falk to bring the detective back for a series of premium, two-hour television movies.

  • 1989: After an 11-year absence, Columbo returns to television with Season 8. Later that year, Season 9 launches.
  • 1990: Season 9 concludes in May. ABC abandons the rigid, seasonal formatting, shifting the series into occasional, high-budget “TV Specials”. Season 10 officially begins with “Columbo Goes to College” in December.
  • 1991: Three major movie specials are broadcast: “Caution: Murder Can Be Hazardous to Your Health”, “Columbo and the Murder of a Rock Star”, and “Death Hits the Jackpot”.
  • 1992: Two movie specials air: “No Time to Die” (a rare episode where Columbo solves a kidnapping rather than a murder) and “A Bird in the Hand…”.
  • 1993: Only one special is produced and broadcast this year: “It’s All in the Game”, written by Peter Falk himself.
  • 1994: Two movie specials air: “Butterfly in Shades of Grey” (featuring William Shatner’s second appearance as a Columbo villain) and “Undercover”.
  • 1995: A single movie special is broadcast: “Strange Bedfellows”, co-starring George Wendt.
  • 1997: Following a brief hiatus, “A Trace of Murder” airs to celebrate the 30th anniversary of the franchise.
  • 1998: The movie special “Ashes to Ashes” is broadcast, featuring Patrick McGoohan, who also directed several episodes of the series.
  • 2001: “Murder With Too Many Notes” airs after a multi-year delay in production.
  • 2003: The 69th and final episode, “Columbo Likes the Nightlife”, airs on 30 January. This concludes the historic run of the franchise, as Peter Falk formally retires from playing the character before his passing in 2011.

Agile Projects Overview and Timeline by year

Agile project management is an iterative, adaptive approach that breaks projects down into small, manageable cycles called sprints or iterations. Instead of planning the entire project upfront, teams continuously deliver functional increments, gather immediate feedback, and adapt to changing requirements. It prioritizes team collaboration, customer involvement, and rapid value delivery over rigid documentation and sequential phases.

Comprehensive Timeline Breakdown by Era and Year

Era 1: The Foundational Seeds (1950s – 1980s)

Before “Agile” existed as a formal term, engineers and researchers laid the groundwork through lean manufacturing and early iterative computing.

  • 1957: IBM begins utilizing incremental development concepts under Gerald M. Weinberg.
  • 1958: Software for Project Mercury (NASA’s first human spaceflight program) is developed using rapid half-day iterations.
  • 1970: Dr Winston Royce publishes a paper describing the Waterfall methodology. Paradoxically, he presents it as high-risk, yet it becomes the dominant, rigid corporate framework for decades.
  • 1980: Toyota refines “Just-In-Time” logistics and visual management system concepts, which later directly inspire Kanban and Lean software practices.
  • 1986: Authors Hirotaka Takeuchi and Ikujiro Nonaka publish “The New New Product Development Game” in the Harvard Business Review. They introduce a holistic, “rugby-style” team approach, coining the term “Scrum”.
  • 1988: Dr Barry Boehm introduces the Spiral Model, formalizing risk-driven, iterative lifecycle planning.

Era 2: The “Lightweight” Revolt (1990s)

Driven by frustration over the high failure rates and slow delivery of Waterfall, software pioneers independently build faster, more flexible frameworks.

  • 1991: James Martin formalizes Rapid Application Development (RAD), highlighting timeboxing, prototyping, and active customer involvement.
  • 1993: Jeff Sutherland, John Scumniotales, and Jeff McKenna deploy the very first operational Scrum process at Easel Corporation.
  • 1994: The Dynamic Systems Development Method (DSDM) is launched in the UK, providing one of the earliest structured frameworks for iterative project delivery.
  • 1995: Ken Schwaber and Jeff Sutherland co-present the formal Scrum Framework to the public at the OOPSLA conference.
  • 1996: Kent Beck introduces Extreme Programming (XP), introducing core engineering mechanics like pair programming and test-driven development (TDD).
  • 1997: Jeff De Luca and Peter Coad design Feature-Driven Development (FDD) to focus strictly on client-valued functional results.

Era 3: The Manifesto Moment (2000 – 2001)

The pivotal pivot point where separate iterative movements unite into a single, cohesive global movement.

  • 2000: Pre-meeting alignment occurs. Martin Fowler publishes his definitive article on Continuous Integration (CI), and Extreme Programming teams begin adopting Scrum’s three-question daily standup format.
  • February 2001: The Agile Manifesto is Born. Seventeen software development pioneers meet at a ski resort in Snowbird, Utah. They discover common ground, author the Manifesto for Agile Software Development, and establish the 4 Core Values and 12 Principles.
  • Late 2001: The Agile Alliance non-profit is established to safeguard, evolve, and distribute Agile education globally.

Era 4: Mainstream Adoption & Scaling (2002 – 2019)

Agile shifts from a rebellious IT trend into a standard corporate expectation, requiring frameworks that can scale across massive enterprises.

  • 2002: Ken Schwaber co-founds the Scrum Alliance to offer standardized certifications (like Certified ScrumMaster), dramatically accelerating global adoption.
  • 2003: Mary and Tom Poppendieck publish Lean Software Development, cleanly mapping Toyota’s manufacturing efficiencies directly onto digital projects.
  • 2009: The Software Craftsmanship Manifesto is created to ensure technical excellence and code quality are not forgotten during rapid business sprints.
  • 2011: Dean Leffingwell releases the Scaled Agile Framework (SAFe), allowing massive corporate enterprises to align hundreds of agile teams across entire portfolios.
  • 2015: Global project management authorities officially pivot; AXELOS releases PRINCE2 Agile, and the Project Management Institute (PMI) introduces Agile certifications into its core curriculum.

Era 5: Modern Continuous Agility (2020s – Present)

Agile transcends IT entirely, cementing its place as an overarching organizational strategy for business survival in an uncertain world.

  • 2020: The Scrum Guide receives its most significant structural update, streamlining language, eliminating prescriptive micro-management, and focusing intensely on a single, unified team working toward a singular “Product Goal”.
  • 2021–2023: Business Agility explodes. Non-technical departments—including HR, Marketing, Legal, and Finance—broadly restructure their workflows into iterative agile backlogs to manage volatile hybrid work environments.
  • 2024–Present: AI-Driven Agility becomes standard practice. Project management tools use generative AI to automatically draft user stories, estimate team velocity, and dynamically rewrite project sprint backlogs based on real-time market shifts.

BASE24 and BASE24-eps architecture overview

The BASE24 electronic payment system developed by ACI Worldwide exists in two primary architectural generations:

BASE24 Classic (historically deployed on HPE NonStop / Tandem fault-tolerant hardware) and

BASE24-eps (Enterprise Payments System, built using an object-oriented C++ framework deployable across open systems, z/OS, and cloud infrastructure).

Despite structural differences, both share a highly optimized, component-based transaction routing engine.

Core Structural Component Layers

The component architecture maps the complete end-to-end lifecycle of a financial message (such as ISO 8583) through five distinct functional sub-systems:

1. Network & Message Routing Component (XPNET)

  • Purpose: Coordinates all message traffic across internal processes and physical network nodes.
  • Function: Operates as a specialized middleware network manager that decouples low-level communication links from upper transaction routing layers.
  • Configuration: Relies on a Logical Network Configuration File (LCONF) to define active execution nodes, hardware lines, and physical stations.

2. Perimeter Access Layer (Device Handlers)

  • Purpose: Translates device-specific message protocol formats into the system’s unified internal format.
  • ATM Device Handlers (ATMDH): Manage direct connectivity to automated teller machines, unpack specific vendor dialects (such as Diebold or NCR states), and track terminal hardware statuses.
  • POS Device Handlers (POSDH): Interface with point-of-sale acquirer terminals and merchants.
  • Security Operations: Triggers immediate payload encryption/decryption and Hardware Security Module (HSM) PIN-block translation directly within this ingestion ring.

3. Core Transaction Logic (Authorization System)

  • Purpose: Determines whether a payment request should be accepted, rejected, or modified.
  • Full On-Us Authorization: Inspects internal databases for matching account records, positive balances, and velocity thresholds to issue real-time decisions.
  • Parametric/Negative Checks: Validates card status against offline negative files, usage restrictions, or custom risk parameters.
  • Scripting Engine: Modern BASE24-eps variants execute localized transaction routing scripts via customized operators without forcing a compile rewrite of the core engine core.

4. Boundary Channels (Interchange & Host Interfaces)

  • Interchange Interfaces (ICH): Package and transform the transaction payload into international network profiles (e.g., Visa, Mastercard, regional switches). It handles strict message mapping and regional network check requirements.
  • Host Interfaces (HIF): Create synchronous links back to an institution’s underlying Core Banking system to apply ledger adjustments, check balances, or execute real-time holds.

5. Offline & Administrative Subsystems

  • Extract Component: Gathers active transaction logs and streams filtered payloads out to analytical reporting databases.
  • Refresh Component: Updates terminal operational data, key packages, and card exclusion lists from parent systems down to active execution nodes.
  • Settlement Initiator: Groups, cleanses, and batches net-clearing totals to finalize payment entries into regional clearinghouses.

Architectural Divergence: Classic vs. EPS

The structural design varies significantly depending on the generation of the software deployment:

BASE24 and BASE24-eps architecture overview
BASE24 and BASE24-eps architecture overview

End-to-End Component Transaction Flow

  1. An ATM transaction arrives at the network interface layer managed by XPNET.
  2. The message is routed to the Device Handler, which strips hardware packaging and requests translation from the HSM.
  3. The clean internal message passes to the Authorization Engine.
  4. If it is a “Not-On-Us” card, the engine identifies the destination BIN and transfers routing control to the Interchange Interface.
  5. The Interchange Interface maps the payload to the external scheme standard (such as Visa) and transmits it to the external network.
  6. The outbound network response is unwrapped by the Interchange component and tracked through the core engine to log final response codes.
  7. The transaction safely records inside the active log file, allowing the Extract / Settlement components to pick it up later during batch processing.

Prince2 or PMP Overview

Prince2 or PMP Overview
Prince2 or PMP Overview

Choosing between PRINCE2 and PMP depends on your career goals and location. PMP is a global, experience-based standard highly valued in the US and multinational corporations. PRINCE2 is a process-based methodology heavily favored in the UK, Europe, and government/public sectors.

A high-level text overview highlights the following core differences:

Project Management Professional (PMP)

  • What it is: A globally recognized framework and body of knowledge (PMBOK) that certifies a manager’s broad project leadership skills.
  • Focus: People, processes, and business domains. It is highly flexible and covers predictive (waterfall), agile, and hybrid methodologies.
  • Requirements: Strict prerequisites. Requires 36–60 months of project management experience and 35 hours of project management education before you can take the 180-question exam.
  • Best for: Experienced project managers seeking global mobility and opportunities in corporate and private sectors.
  • Official Hub: Learn more and apply via the Project Management Institute.

PRINCE2 (PRojects IN Controlled Environments)

  • What it is: A structured, prescriptive methodology that gives you a step-by-step guide on how to run a project from start to finish.
  • Focus: Governance, defined roles, continuous business justification, and documentation. It uses a scaleable “Tailoring Approach” so it can be adapted to projects of varying sizes.
  • Requirements: No mandatory experience needed for the Foundation level, making it accessible to beginners. The Practitioner level tests your ability to apply the framework.
  • Best for: Early-to-mid career professionals and those targeting government, NHS, or public sector roles within the UK and Europe.
  • Official Hub: Browse certification pathways via Axelos.

Project Management Office (PMO) models overview

Project Management Office (PMO) models dictate the structure, control level, and strategic focus of a PMO within an organization. The most common frameworks break down into three primary operational types, alongside broader structural and strategic classifications that define how governance is applied.

Project Management Office (PMO) models overview
Project Management Office (PMO) models overview

1. Operational Models (By Control Level)

These models define how the PMO interacts with project teams and enforces standards.

  • Supportive PMO: Acts as an advisory entity. It provides templates, best practices, training, and tools on demand, but has no direct control or authority over project execution. Best for: Organizations with a decentralized, highly autonomous culture.
  • Controlling PMO: Enforces strict governance, standardizes methodologies, and ensures compliance across all initiatives. It provides more than advice and actively verifies adherence, but typically relies on established escalation paths rather than direct authority. Best for: Organizations that need consistency and reduced risk.
  • Directive PMO: Assumes full control and direct ownership of projects. The PMO assigns project managers, directs resources, and takes total responsibility for execution, timelines, and outcomes. Best for: Complex or mission-critical projects requiring rigid governance.

2. Structural Models (By Scope & Placement)

These classifications indicate where the PMO sits and its organizational reach.

  • Enterprise PMO (EPMO): Operates at the highest organizational level, overseeing the entire project portfolio. It ensures all programs directly align with overarching corporate business objectives and strategy.
  • Departmental/Divisional PMO: Supports specific business units (such as IT, Marketing, or Engineering). It is highly tailored to the specialized needs of that function, though it runs the risk of creating siloed practices.
  • Embedded or Project-Specific PMO: A temporary model dedicated to one large, highly complex, or mission-critical project or program. It lasts for the duration of the project and then disbands or reallocates.

3. Advanced / Strategic Models (By Focus)

Modern organizations often adapt the PMO to focus on high-level value rather than just tracking timelines.

  • Center of Excellence (CoE): Focuses heavily on continuously elevating the organization’s project management maturity. It acts as an innovation hub for methodologies, technology evaluation, and skill-building.
  • Value Management Office (VMO): Focuses entirely on benefits realization and return on investment (ROI). Rather than just asking “are we on time?”, it asks “is this project generating the business value we wanted?”

Project Management Office (PMO) Overview

A Project Management Office (PMO) is a centralized department or group that defines, maintains, and ensures project management standards across an organization. It serves as the “command center” that aligns project execution with broader business strategy to improve success rates and ROI.

Core PMO Models

The level of control a PMO exerts depends on its specific operational model:

  • Supportive PMO: Provides a consultative role by supplying templates, best practices, and training. It has low control, acting primarily as a project repository.
  • Controlling PMO: Enforces governance and requires compliance through specific frameworks and tools. It maintains a moderate degree of control.
  • Directive PMO: Directly manages projects by assigning project managers who report to the PMO. This model offers the highest degree of control and accountability.

Key Responsibilities

A PMO’s daily functions bridge the gap between high-level strategy and ground-level execution:

Common PMO Roles:

Common PMO Roles

Staffing varies by organization size, but typical roles include:

  • PMO Director/Manager: Oversees the entire office, ensuring processes are followed and goals are met.
  • PMO Analyst: Collects and analyzes project data to support decision-making and reporting.
  • Project/Portfolio Managers: Lead individual projects or entire portfolios to completion.
  • PMO Specialist: Focuses on implementing methodologies and providing expert advice on project management.

Organizational Levels

PMOs can operate at different tiers within a company:

  • Project PMO: Focused on a single, large-scale project.
  • Program/Department PMO: Oversees a group of related projects within a specific department (e.g., IT or Marketing).
  • Enterprise PMO (EPMO): Operates at the executive level, ensuring all projects across the entire organization align with strategic corporate goals.

Agile Scrum Overview and Evolution Timeline

Agile Scrum is a widely adopted, iterative, and incremental framework designed to manage complex product development and software projects.

It breaks down large, daunting projects into small, manageable units called sprints—fixed-length iterations typically lasting 1–4 weeks—to deliver functional components faster and adapt to changing requirements.

Detailed Summary of the Scrum Framework

Scrum relies on three pillars—transparency, inspection, and adaptation—and is defined by specific roles, events, and artifacts.

1. The Scrum Team (Roles)

  • Product Owner (PO): Maximizes the value of the product by managing the Product Backlog. They define “what” is built.
  • Scrum Master: A servant-leader who helps the team follow Scrum theory and removes impediments.
  • Developers: The cross-functional team members responsible for creating the increment each sprint.

2. Scrum Events (Ceremonies)

  • Sprint Planning: Defines the Sprint Goal and the work to be done during the sprint.
  • Daily Scrum: A 15-minute daily meeting for developers to synchronize activities and plan the next 24 hours.
  • Sprint Review: Held at the end of the sprint to showcase the increment to stakeholders and gather feedback.
  • Sprint Retrospective: The team reflects on the process and identifies improvements for the next sprint.

3. Scrum Artifacts

  • Product Backlog: An ordered list of everything required in the product.
  • Sprint Backlog: The set of Product Backlog items selected for the sprint, plus the plan for delivering them.
  • Increment: The usable, working product increment produced at the end of a sprint.

Evolution of Scrum Over the Years

Scrum was developed in the early 1990s as a response to the failures of the linear “waterfall” approach.

  • 1986 (Concept Origins): Takeuchi and Nonaka publish “The New New Product Development Game,” comparing traditional relay-race product development to a rugby “scrum” team.
  • 1993 (First Implementation): Jeff Sutherland, John Scumniotales, and Jeff McKenna implement the first Scrum team at Easel Corporation.
  • 1995 (Public Introduction): Ken Schwaber and Jeff Sutherland formalize Scrum and present “The Scrum Development Process” at the OOPSLA ’95 conference.
  • 2001 (Agile Manifesto): Sutherland and Schwaber become signatories of the Agile Manifesto, cementing Scrum as a major Agile methodology.
  • 2010 (The Scrum Guide): The first official Scrum Guide is released to standardize the framework worldwide.
  • 2011–2017 (Refinements): The guide is updated to clarify roles and events, including strengthening the role of the Scrum Master and introducing self-organizing teams.
  • 2020 (The Modern Scrum Guide): A major update makes the guide less prescriptive, focusing on a single Scrum Team (removing “development team” and “scrum team” split), introducing the Product Goal for long-term focus, and focusing on one team working towards one product.
