The accuracy of estimates is a function of the stage of development (i.e. estimates improve as development of the item progress). This also means that estimates for development projects representing only 'modest advances' tend to be better than for more ambitious projects.
The employment of the poor in roads and public works, and a tendency among landlords and persons of property to build, to improve and beautify their grounds, and to employ workmen and menial servants, are the means most within our power and most directly calculated to remedy the evils arising from that disturbance in the balance of produce and consumption.thomas malthus
Collaboration is being open to each other's ideas and benefiting from each other's perspectives in an open way. Collaboration is all about rewriting and rewriting and rewriting and helping each other to constantly improve a piece. And, it's also about spurring each other on to doing really great, hard work — it's easier to do it in a collaboration than on your own.alan menken
Sometimes one can improve the theories in the sense of discovering a quicker, more efficient way of doing a given calculation.describing his discoveries in Density functional theory, December 29, 1995, in an interview with István Hargittai, Magdolna Hargittai (2000).

Know that death comes to everyone, and that wealth will sometimes be acquired, sometimes lost. Whatever griefs mortals suffer by divine chance, whatever destiny you have, endure it and do not complain. But it is right to improve it as much as you can, and remember this: Fate does not give very many of these griefs to good people.pythagoras
Every man has at times in his mind the ideal of what he should be, but is not. This ideal may be high and complete, or it may be quite low and insufficient; yet in all men that really seek to improve, it is better than the actual character. * * * Man never falls so low that he can see nothing higher than himself.theodore parker
A great deal of the thinking [in Organizational Development] has been influenced by cybernetics and information theory, though this has been used as much to extend the scope of closed-system as to improve the sophistication of open system formulations. It was von Bertalanffy (1950) who, in terms of the general transport equation which he introduced, first fully disclosed the importance of openness or closedness to the environment as a means of distinguishing living organisms from inanimate objects.Fred Emery and Eric Trist (1963) "The Causal Texture of Organizational Environments". In: Human Relations, 18: p. 22
If you want to improve the world, first improve yourself. If you want to improve yourself, read a book.J. Millard Simpson, "Thoughts On The Collapse" (2009).
Of all God's creatures there is only one that cannot be made the slave of the leash. That one is the cat. If man could be crossed with the cat it would improve man, but it would deteriorate the cat.Mark Twain, in Mark Twain's Notebook, prepared by Albert B. Paine (1935, reprinted 1972), pp. 236–37.
I have no doubt that playing today's games does in fact improve your visual intelligence and your manual dexterity, but the virtues of gaming run far deeper than hand-eye coordination.Steven Johnson, in Everything Bad is Good for You, Penguin, 2 May 2006, p.24
...if you take up video-gaming, even casually, you can expect the following benefits: decreased overall reaction times, increased eye-hand coordination, and enhanced manual dexterity. You'll improve your spatial visualization skills and your ability to mentally work in three dimensions.Richard Restak, in Donald B. Egolf, Human Communication and the Brain: Building the Foundation for the Field of Neurocommunication, Lexington Books, 5 April 2012, p.11
"Chiropractic, which focuses on manipulating the spine to ease back pain and improve overall health, has won wider acceptance over the years. Most health insurance plans now cover it. But in the 110 years since the profession was created, the established medical community largely has boycotted it challenging its scientific validity in courts and legislative bodies."(Washington Times)
