The Mythical Man-Month: Essays on Software Engineering is a book on software engineering and project management by Fred Brooks first published in 1975, with subsequent editions in 1982 and 1995. Its central theme is that adding manpower to a software project that is behind schedule delays it even longer. This idea is known as Brooks's law, and is presented along with the second-system effect and advocacy of prototyping.
The program evaluation and review technique (PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project.
Brooks' law is an observation about software project management according to which adding more individuals to a software project that is behind schedule delays it even longer. It was coined by Fred Brooks in his 1975 book The Mythical Man-Month. According to Brooks, under certain conditions, an incremental person when added to a project makes it take more, not less time.
Efficiency is the often measurable ability to avoid wasting materials, energy, efforts, money, and time while performing a task. In a more general sense, it is the ability to do things well, successfully, and without waste.
A business process, business method or business function is a collection of related, structured activities or tasks performed by people or equipment in which a specific sequence produces a service or product for a particular customer or customers. Business processes occur at all organizational levels and may or may not be visible to the customers. A business process may often be visualized (modeled) as a flowchart of a sequence of activities with interleaving decision points or as a process matrix of a sequence of activities with relevance rules based on data in the process. The benefits of using business processes include improved customer satisfaction and improved agility for reacting to rapid market change. Process-oriented organizations break down the barriers of structural departments and try to avoid functional silos.
An office is a space where the employees of an organization perform administrative work in order to support and realize the various goals of the organization. The word "office" may also denote a position within an organization with specific duties attached to it ; the latter is an earlier usage, office as place originally referring to the location of one's duty. In the adjective form, the term "office" may refer to business-related tasks. In law, a company or organization has offices in any place where it has an official presence, even if that presence consists of a storage silo, for example, instead of a more traditional establishment with a desk and chair. An office is also an architectural and design phenomenon, including small offices, such as a bench in the corner of a small business or a room in someone's home, entire floors of buildings, and massive buildings dedicated entirely to one company. In modern terms, an office is usually the location where white-collar workers carry out their functions.
Scientific management is a theory of management that analyzes and synthesizes workflows. Its main objective is improving economic efficiency, especially labor productivity. It was one of the earliest attempts to apply science to the engineering of processes to management. Scientific management is sometimes known as Taylorism after its pioneer, Frederick Winslow Taylor.
Henry Laurence Gantt was an American mechanical engineer and management consultant who is best known for his work in the development of scientific management. He created the Gantt chart in the 1910s.
In economics, the lump of labour fallacy is the misconception that there is a finite amount of work—a lump of labour—to be done within an economy which can be distributed to create more or fewer jobs. It was considered a fallacy in 1891 by economist David Frederick Schloss, who held that the amount of work is not fixed.
A part-time job is a form of employment that carries fewer hours per week than a full-time job. They work in shifts. The shifts are often rotational. Workers are considered to be part-time if they commonly work fewer than 30 hours per week. According to the International Labour Organization, the number of part-time workers has increased from one-quarter to a half in the past 20 years in most developed countries, excluding the United States. There are many reasons for working part-time, including the desire to do so, having one's hours cut back by an employer and being unable to find a full-time job. The International Labour Organisation Convention 175 requires that part-time workers be treated no less favourably than full-time workers.
Work-to-rule is a job action in which employees do no more than the minimum required by the rules of their contract or job, and strictly follow time-consuming rules normally not enforced. This may cause a slowdown or decrease in productivity if the employer does not hire enough employees or pay the appropriate salary and as such does not have the requirements needed to run at the level they desire. It is a form of protest against low pay and poor working conditions, and is considered less disruptive than a strike or lockout as obeying the rules is not susceptible to disciplinary action or loss of pay. It can also highlight rules that are technically in place but impractical and thus hamper the organization, if they were to be followed as written.
Permatemp is a U.S. term for a temporary employee who works for an extended period for a single staffing client. The word is a portmanteau of the words permanent and temporary.
Piece work or piecework is any type of employment in which a worker is paid a fixed piece rate for each unit produced or action performed, regardless of time.
Organizing or organising is the establishment of effective authority-relationships among selected works, persons and workplaces in order for a group to work together efficiently, or the process of dividing work into sections and departments, which often improves efficiency.
Takt time, or simply takt, is a manufacturing term to describe the required product assembly duration that is needed to match the demand. Often confused with cycle time, takt time is a tool used to design work and it measures the average time interval between the start of production of one unit and the start of production of the next unit when items are produced sequentially. For calculations, it is the time to produce parts divided by the number of parts demanded in that time interval. The takt time is based on customer demand; if a process or a production line are unable to produce at takt time, either demand leveling, additional resources, or process re-engineering is needed to ensure on-time delivery.
Job performance assesses whether a person performs a job well. Job performance, studied academically as part of industrial and organizational psychology, also forms a part of human resources management. Performance is an important criterion for organizational outcomes and success. John P. Campbell describes job performance as an individual-level variable, or something a single person does. This differentiates it from more encompassing constructs such as organizational performance or national performance, which are higher-level variables.
The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. It uses a kitchen timer to break work into intervals, typically 25 minutes in length, separated by short breaks. Each interval is known as a pomodoro, from the Italian word for tomato, after the tomato-shaped kitchen timer Cirillo used as a university student.
The following is a glossary of terms relating to construction cost estimating.
Socially necessary labour time in Marx's critique of political economy is what regulates the exchange value of commodities in trade and consequently constrains producers in their attempt to economise on labour. It does not 'guide' them, as it can only be determined after the event and is thus inaccessible to forward planning.
Work or labor is the intentional activity people perform to support the needs and wants of themselves, others, or a wider community. In the context of economics, work can be viewed as the human activity that contributes towards the goods and services within an economy.
