Parkinson’s law of triviality” redirects here. 1957 argument that members of an organisation give disproportionate weight to trivial issues. The law has law for engineers book pdf applied to software development and other activities.

He dramatizes this “law of triviality” with the example of a committee’s deliberations on an atomic reactor, contrasting it to deliberations on a bicycle shed. A reactor is so vastly expensive and complicated that an average person cannot understand it, so one assumes that those who work on it understand it. On the other hand, everyone can visualize a cheap, simple bicycle shed, so planning one can result in endless discussions because everyone involved wants to add a touch and show personal contribution. Problems arise after a suggestion of building something new for the community, like a bike shed, causes everyone involved to argue about the details. This is a metaphor indicating that it is not necessary to argue about every little feature based simply on the knowledge to do so.

Some people have commented that the amount of noise generated by a change is inversely proportional to the complexity of the change. 21 a year to supply refreshments for the Joint Welfare Committee. 10 million number is too big and too technical, and it passes in two and a half minutes. One committee member proposes a completely different plan, which nobody is willing to accept as planning is advanced, and another who understands the topic has concerns, but does not feel that he can explain his concerns to the others on the committee. The bicycle shed is a subject understood by the board, and the amount within their life experience, so committee member Mr Softleigh says that an aluminium roof is too expensive and they should use asbestos.

Mr Daring questions the need for the shed at all. Parkinson then writes: “The debate is fairly launched. 350 is well within everybody’s comprehension. Everyone can visualise a bicycle shed. Members at length sit back with a feeling of accomplishment. This item on the agenda will occupy the members for an hour and a quarter, and they will end by asking the secretary to procure further information, leaving the matter to be decided at the next meeting. There are several other principles, well known in specific problem domains, which express a similar sentiment.

A countermeasure is the duck technique in corporate programming: a programmer expects their corporate office to insist on at least one change on every presentation to show that they’re participating, regardless of the benefits of that change. Consequently, the programmer intentionally adds an element they expect corporate to remove. The assumption was that subconsciously they felt that if they didn’t, they weren’t adding value. He did the animations for the queen the way that he felt would be best, with one addition: he gave the queen a pet duck. He animated this duck through all of the queen’s animations, had it flapping around the corners.

He also took great care to make sure that it never overlapped the “actual” animation. Eventually, it came time for the producer to review the animation set for the queen. The producer sat down and watched all of the animations. When they were done, he turned to the artist and said, “That looks great.

Just one thing: get rid of the duck. Why Should I Care What Color the Bikeshed Is? Frequently Asked Questions for FreeBSD 7. Chartered Institute of Transport, p.

Hacker Culture: Who was Brett Glass as named in the original “bikeshed” email? This page was last edited on 6 December 2017, at 08:28. This article is about the industrial action. Unsourced material may be challenged and removed. A slowdown may be used as either a prelude or an alternative to a strike, as it is seen as less disruptive as well as less risky and costly for workers and their union.

Striking workers usually go unpaid and risk being replaced, so a slowdown is seen as a way to put pressure on management while avoiding these outcomes. Other times slowdowns are accompanied by intentional sabotage on the part of workers to provide further disruption. Nonetheless, workers participating in a slowdown are often punished, sometimes by firing and other times by law. 18 to 21 feet per minute.

This was a second speed increase, and workers felt that this was unfair. After a go-slow by production line staff, Ford management reduced the line speed back to 18 feet per minute. Another form of slowdown is known as the rule-book slowdown. This refers to the “rule books” that govern workers’ actions, usually either for safety or quality purposes. In practice, many rules are loosely interpreted in the interest of efficiency. A union seeking to employ a slowdown tactic may take advantage of these common rule oversights by having workers “work to rule”, obeying each and every rule to the fullest extent, which consequently will greatly reduce productivity.

This has the advantage of allowing workers and unions to claim that no malfeasance is being committed, since they are doing only what the management’s rules actually require them to do. For instance, many subways are required to keep doors open for a certain amount of time at each stop, whereas in practice doors are often closed sooner. Likewise, a bus driver typically may take the same liberties with traffic law that drivers do, and are often overloaded with passengers, while an experienced pilot can safely fly in some inclement weather. In a “rule-book” slowdown, the bus driver may drive more slowly and conservatively and with a proper passenger load, while the pilot may refuse to fly in mildly inclement weather.
