1820's | ||||
1822 | Difference engine (Babbage) | The English inventor Charles Babbage starts working on a prototype of his first difference engine. The difference engine is made to compute values of polynomial functions. Babbage's machines were among the first mechanical computers. | ||
1840's | ||||
1843 | Methods of inductive reasoning (Mill) | In the A System of Logic the British philosopher John Stuart Mill publishes five methods of inductive reasoning; the reasoning from a specific case or cases to a general rule. The fundamental principle of induction is the proposition that the course of nature is uniform. | ||
Lovelace's notes on the Analytical Engine | During a nine-month period in 1842–43, Lovelace translates Italian mathematician Luigi Menabrea's memoir on Charles Babbage's Analytical Engine. With the article, she appends a set of notes. The notes include a method for calculating a sequence of Bernoulli numbers with the Engine. Based on this work, Lovelace is now widely credited with being the first computer programmer and her method is recognised as the world's first computer program. | |||
1870's | ||||
1878 | System flaw termed as bug (Edison) | According to the The Yale Book of Quotations the American inventor Thomas Alva Edison uses the term 'bug' in a letter to Theodore Puskas to describe a flaw in a system. According to other sources the term bug was commonly used to describe systems faults in Edison's time. | ||
1890's | ||||
1896 | IBM founded | The company which becomes IBM is founded in 1896 as the Tabulating Machine Company by Herman Hollerith in Broome County, New York. It is incorporated as Computing Tabulating Recording Corporation on June 16, 1911. The company is named International Business Machines Corporation (IBM) in 1924. | ||
1900's | ||||
1906 | Pareto Principle (80/20 rule) | In his book Manual of Political Economy the Italian economist Vilfredo Pareto publishes the mathematical formula to describe the unequal distribution of wealth in his country, observing that twenty percent of the people owned eighty percent of the wealth. The formula becomes known as the Pareto principle but also, through popularization by Joseph Juran, as the 80/20 rule. | ||
1930's | ||||
1939 | Shewhart Cycle | In his second book Statistical Method from the Viewpoint of Quality Control Walter Andrew Shewhart publishes his Scientific Method of Improvement. Page 45 of this book displays the first version of the Shewhart Cycle; a three step cycle constituting a dynamic scientific process of acquiring knowledge. Walter Edwards Deming later popularizes the method as the Plan Do Check Act method (The Deming Cycle). | ||
1940's | ||||
1944 | Harvard Mark I installed | The Harvard Mark I, also known as the IBM Automatic Sequence Controlled Calculator (ASCC), is installed at Harvard and formally presented on August 7, 1944. The Mark I is a parallel synchronous calculator that can perform table lookup and the four fundamental arithmetic operations, in any specified sequence, on numbers up to 23 decimal digits in length. The machine was conceived by Howard H. Aiken in the 1930s. | ||
1945 | Von Neumann architecture | In the paper First Draft of a Report on the EDVAC John von Neumann published the description of the logical design of a computer using the stored-program concept. This is the design on which most computers nowadays are based. The paper is distributed on June 30, 1945 by Herman Goldstine. | ||
1946 | ISO founded | The International Organization for Standardization (ISO) is founded during a conference in London in 1946. ISO is born from the union of two organizations; the ISA (International Federation of the National Standardizing Associations), established in New York in 1926 and the UNSCC (United Nations Standards Coordinating Committee), established in 1944. | ||
1949 | On Checking a Large Routine (Turing) | In the conference paper On Checking a Large Routine Alan M. Turing proposes an answer to the question how one can check a routine in the sense of making sure that it is right. | ||
1950's | ||||
1950 | Turing Test (Turing) | In his 1950 paper Computing Machinery and Intelligence Alan M. Turing introduces the Turing Test; a test of a machine's ability to demonstrate intelligence. | ||
1951 | Juran's Quality Control Handbook (Juran) | In his book Juran's Quality Control Handbook Joseph M. Juran defines quality as 'fitness for use'. Juran, who is considered to be the founding father of quality management, defines three processes for the management of quality; quality planning, quality control and quality improvement. | ||
Total Quality Control (Feigenbaum) | In his famous book 'Total Quality Control' Armand Vallin Feigenbaum defines quality as a customer determination. Quality depends on the perspective of the customer. The product should satisfy the customer in both actual and expected needs. There is a company-wide responsibility for quality. | |||
First practical text on programming (Wilkes) | The book The Preparation of Programs for an Electronic Digital Computer by authors Maurice V. Wilkes, David J. Wheeler and Stanley Gill is the first practical text on computer programming. The authors draw on their experience from designing the EDSAC. | |||
1952 | IBM 701 released | The IBM 701 Defense Calculator is IBM's first production computer. It is the first of the very popular IBM 700 series. The computer contains two electrostatic storage units and an electronic analytical and control unit. 19 units are created. A unit rented for about $16,000 per month. | ||
1956 | First Fortran manual | The first Fortran manual (an automatic coding system for the IBM 704) is published by IBM in October 1956. It describes the variables, functions, expressions and control statements of the language. | ||
1957 | Program testing vs debugging (Baker) | Charles L. Baker (RAND Corporation) distinguishes program testing from debugging in his review of the book Digital Computer Programming by Dan McCracken. The review is published in the journal Mathematical Tables and Other Aids to Computation. | ||
Digital Computer Programming (McCracken) | Daniel D. McCracken's book Digital Computer Programming is perhaps the first general textbook on programming. McCracken writes the book while working for General Electric. He discusses a number of programming techniques such as program checkouts. McCracken specifically advises using break points in a program at which the functioning of the program may be verified. | |||
1958 | First software test team (Weinberg) | The first test team is formed by Gerald M. Weinberg, working as manager of Operating Systems Development for the Project Mercury. Project Mercury is the first human spaceflight program of the United States. | ||
1959 | Work Breakdown Structure | In their classic paper Program Evaluation and Review Technique (PERT) D.G. Malcolm, J.H. Roseboom, C.E. Clark and W. Fazar introduce their method to analyze the involved tasks in completing a given project. Although not mentioned by that name in the paper they also introduce the Work Breakdown Structure. | ||
Critical-Path Method (Kelley, Walker) | In their paper Critical-Path Planning and Scheduling James E. Kelley and Morgan R. Walker offer a planning and scheduling methodology for complex projects. They introduce the Critical-Path Method in order to create optimal direct cost schedules. The authors use project diagrams of tasks and link these tasks (jobs) based on three questions; what immediately precedes this job, what immediately follows this job and what can be concurrent with this job? | |||
1960's | ||||
1961 | Computer Programming Fundamentals (Leeds, Weinberg) | The book Computer Programming Fundamentals by Gerald Weinberg and Herbert Leeds contains a chapter on software testing. Weinberg and Leeds argue that testing should prove the adaptability of a computer program instead of its ability to process information. | ||

1967 | Evaluation of the Functional Testing of Control Programs | In the IBM white paper Evaluation of the Functional Testing of Control Programs William Elmendorf calls for a disciplined approach to software testing. | ||
Software engineering introduced | The term 'software engineering' is coined by a NATO study group that recommends a conference to discuss 'the problems of software'. The report from the ensuing 1968 conference, which was sponsored by the NATO Science Committee and took place in Garmish, Germany, is titled Software Engineering. Brian Randell and Peter Naur point out in the introduction to their edition of the proceedings, "The phrase 'software engineering' was deliberately chosen as being provocative, in implying the need for software manufacture to be [based] on the types of theoretical foundations and practical disciplines[,] that are traditional in the established branches of engineering. | |||
1968 | NATO report mentions Software Quality Assurance | During the Software Engineering conference sponsored by the NATO Science Committee (7th to 11th October 1968) among other things quality assurance for software production is one of the topics. The report of the conference includes the working paper Checklist for planning software system production by Robert W. Bemer. This paper contains a chapter on quality assurance. One of the questions in the checklist is 'Is the product tested to ensure that it is the most useful for the customer in addition to matching functional specifications?'. | ||
Structured programming (Dijkstra) | In his letter Go To Statement Considered Harmful published in the March 1968 Communications of the ACM, Edsger Dijkstra criticizes the excessive use of the GOTO statement in programming languages. Dijkstra considers the usage harmful because it complicates the task of analyzing and verifying the correctness of programs. The letter is usually cited as the beginning of the structured programming debate | |||
Intel founded | Intel is founded by Gordon E. Moore and Robert Noyce. In the beginning the company's primary products are static random access memory (SRAM) chips. Intel releases the first commercially available microprocessor (Intel 4004) in 1971. | |||
Software crisis (Bauer) | The term 'software crisis' is coined by Friedrich Ludwig Bauer at the first NATO Software Engineering Conference in 1968 in Garmisch-Partenkirchen, Germany. It refers to the difficulty of writing correct, understandable, and verifiable computer programs. | |||
Conway's Law | In his 1968 paper How Do Committees Invent? Melvin E. Conway publishes the thesis that "Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure.". The thesis later becomes known as Conway's Law. | |||
1969 | Testing shows the presence, not the absence of bugs | Edsger Dijkstra's famous quote was reportedly first spoken on a conference by the NATO Science Committee, Rome, Italy, 27–31 October 1969. | ||

1970's | ||||
1970 | Waterfall model published (Royce) | Winston Royce describes a waterfall model in the paper Managing the Development of Large Software Systems, presented to IEEE WESCON in 1970. The waterfall model is a sequential software development process. In his paper Royce also mentions the shortcomings of the waterfall and warns against using the method. | ||
Relational model published (Codd) | In his paper A Relational Model of Data for Large Shared Data Banks Edgar F. Codd, working for IBM, publishes the relational model for data. His theory paves the way for relational databases. | |||
1971 | Mutation testing (Lipton) | In a class term paper titled Fault Diagnosis of Computer Programs Richard Lipton proposed the initial concepts of mutation. Mutation testing is a methodology for unit testing in which small parts of the code are changed. This is done, for example, in order to test the quality of the unit tests. | ||
1972 | Systems decomposition (Parnas) | In his famous paper On the Criteria to Be Used in Decomposing Systems into Modules David Lorge Parnas discusses the benefits of modular programming. | ||
Proof of correctness as guidance (Dijkstra) | In his ACM Turing Lecture titled The Humble Programmer Edsger W. Dijkstra states that "One should not first make the program and then prove its correctness, because then the requirement of providing the proof would only increase the poor programmer's burden." It is one of his arguments in support of the technical feasibility of the change required in software programming. | |||
1973 | Program Test Methods (Hetzel) | The Chapel Hill Symposium, organized by the University of North Carolina and held on June 21-23 1972, leads to publication of the book Program Test Methods edited by William Hetzel. The book contains the edited papers of the symposium as well as a large annotated bibliography. The book focuses on the problems in testing and validation. | ||

Brooks' law | In the book The Mythical Man-Month: Essays on Software Engineering Fred Brooks presents the central theme that "adding manpower to a late software project makes it later". This idea is known as Brooks' law, and is presented along with the second-system effect and advocacy of prototyping. Brooks draws from his experience as a manager of the development of IBM OS/360. | |||
Introduction to General Systems Thinking (Weinberg) | In his book An Introduction to General Systems Thinking Gerald M. Weinberg offers a clear view on systems theory. According to Weinberg it is an attempt "to teach an approach to thinking when the labels are missing, or misleading." Understanding the limitations of our tools is a recurring theme in the book. | |||
Altair 8800 introduced | The Altair 8800 is introduced by Micro Instrumentation and Telemetry Systems (MITS) in 1975. It is a microcomputer based on the Intel 8080 processor.

1979 | The Art of Software Testing (Myers) | The book The Art of Software Testing by Glenford Myers is lauded as the first book that is about software testing only. It sets the stage for 'modern' software testing. Among other things Myers introduces black box testing. He also poses the 'Triangle Program' as a testing self-assessment challenge. | ||
Quality is Free (Crosby) | In his book Philip B. Crosby describes his famous 14-step program for quality improvement. Crosby defines quality as conformance to requirements. He defines the 'Quality Maturity Grid' and classifies management attitudes toward quality into five categories. Crosby suggests that improvement happens as management 'matures' from one category to another. | |||

Structured Analysis and System Specification (DeMarco) | The book Structured Analysis and System Specification by Tom DeMarco is a classic on structured analysis. DeMarco covers functional decomposition, data dictionary, process specification, system modeling and structured analysis for a future system. He suggests an approach that emphasizes a top-down, partitioned, graphic model of the system-to-be. He also stresses the important role of a data dictionary and the role of scaled-down specifications, or minispecs, to be written in a rigorous subset of the English language known as Structured English. | |||
Function points (Albrecht) | In his paper Measuring Application Development Productivity Allan Albrecht, working for IBM, introduces the function point in order to measure programmer productivity. Albrecht concludes from his study of productivity that a discplined process is "an essential ingredient to meaningful productivity measurement". | |||
1980's | ||||
1981 | Software Engineering Economics (Boehm) | In the landmark book Software Engineering Economics Barry W. Boehm introduces the notion that the cost of fixing a bug rises exponentially in time. He also introduces the constructive cost model (COCOMO). | ||
