Why we should start small - http://spin.atomicobject.com[..]3/11/01/minimum-viable-product-benefits/ http://www.yegor256.com[..]4/10/20/how-we-write-product-vision.html Most of product development is the middle part: the messy, weird, unintuitive place where you and your team are making hundreds of small decisions. If you are not looking to real people by continuously conducting user research and running hypothesis-driven tests, you’ll slowly (and with growing confidence) get far away from your actual goal: Making a product for real people. - https://medium.com[..]-things-come-to-think-of-it-42fa3d7cb415 Naming can be difficult - https://www.inside.com.tw/2018/04/16/company-name-is-big-deal

Here is one way of how people estimate percent of completion - http://geekswithblogs.net/optikal/archive/2006/12/31/102381.aspx I believe the general practice in my company is to take your estimate and triple it. Noone EVER complains that a project was completed too quickly. - http://discuss.joelonsoftware.com[..]iscussTopicParent=15151&ixDiscussGroup=3 McConnell: 25% isn't necessarily a bad number. What's bad about it is that the average project is something like 100% late and 100% over budget at the time it's shut down. With better development approaches, a lot of those projects would get shut down when they've used 20% of their budgets rather than 200% of their budgets. http://blogs.cio.com/node/600 Schedule chicken , someone leave the responsiblity to other sliencely - http://www.stickyminds.com[..]ion=edetail&ObjectType=COL&ObjectId=7923 If you need to deliver software in 9 months, you could make a plan to deliver software in 9 months and hope it works. Or you could start delivering software every week. Maybe in the first week you aren't so good at it but after four weeks you and the rest of your team will be better. I call it the reduce risk by practicing technique. I can't believe how many people line up against me on this, even quality experts. - Ward Cunningham Estimate via experience - http://digerati-illuminatus.blogspot.com[..]mating-software-feature-development.html Explain what is Velocity in scrum - http://kw-agiledevelopment.blogspot.com[..]2008/01/understanding-your-velocity.html Concern about estimation - http://agile.dzone.com/news/humans-cant-estimate-tasks http://jimhighsmith.com/2011/11/02/velocity-is-killing-agility/ Test Effort Estimation - http://blogs.siliconindia.com[..]mation_approch-bid-00oQI1TW93593159.html Reducing focus on estimation, I think it is good move, as estimate always inaccurate - http://blog.anandvishwanath.in[..]se-for-reducing-focus-on-estimation.html http://www.scrumexpert.com[..]ng-budget-instead-of-estimates-in-agile/ Discussion about noestimates-software-contractors - http://www.infoq.com[..]2016/01/noestimates-software-contractors http://www.infoq.com[..]2015/12/noestimates-software-contractors https://ronjeffries.com/articles/estimation-articles/

SQL 2005 JDBC fix the resultset re-read throws exception problem.
