1.seven Reasons for Agile Software Development - Introduction to waterfall model

Hey everyone, This is Raja Enterprise Agile Coach from ProXL consulting. welcome to the Agile Scrum training in the first model we are going to discuss the bones seven reasons for my day software development there are so many vietnam developing software 0 the most popular one which is being followed currently by many companies is called waterfall model RB Mark good morning very much in a wonderful morning 0 in this traditional waterfall model software is developed in a sequential manner we stop at the Grauman's analysis that we get to the requirements from the climb once a complete set of requirements like capture be more want to design phase bad the complete set of requirements I been completely redesigned and I but the design is over me want to coding bad that design is gonna let that in Bulgaria scolds using different programming languages after the voting is completed me go to testing bad the Indian programs like this that would check benefits programs are in line with the requirements after the testing is completed the software is delivered to the plans when it is delivered to the plan that could be some issues I kitchens are the customers may if that happens then the sovereign debt and the maintenance be so the some other developers build fix both problems better being passed by the client and then something only this opportunity meeting so this is that because sequence in life cycle model most others of the company following and this is gone the waterfall model primarily because once the requirements of all the requirements and complete their I N rolls on be don't allow any changes to anyone Indian same me been you do when you complete the design and moving the coding there cannot be any changes the design so primarily the water when leaflets dole you cannot make the wonderful up so it has to be doesn't while legislators called 11 tomorrow this model is being followed by many companies that be discussed earlier let's try to understand a bit more deeper into this but you learn more going to stop it all starts with the requirements analysis the Business Analyst of the requirements analyst from this offer organization since the client all the stakeholders all the end users are other them understand all the requirements of the software product that is expected all times ones all the requirements I been and that's good because documentarian doing something called business requirement specification are software requirement specification the ones that equipment specifications are being returned those documents are shown to the Klein on be expect the claim to up bro the documents once the documents and upload the requirements set forth in sort of thing got that will be the basis what's up the clintons will be used the proton requirements document at the bases walk what blanning as well as subsequent technical activities does subsequently be more want to design the complete set of requirements I've been can look billion bulgarians starting with architect to design bad you come up with the high level like the picture on the system once the i cant take dat has been problem and finalized you want to model them when you're leaving the area models and then moved onto unit 9 thought once you complete all the design board high-level on D-day and be free the design if possible you up going back to the customer get that approval aretha used internally the technical team bill review approved once the design have been finally some for them beam 12 warning means in the Gordon faith de programas mob creating various programs in maine bhi that design the book grams on it and in various programming languages because it has been selected and once the complete set up programs I've been called ok then be more wont do best in peace be also do the reviews of this particular program and their families individual programs I've been bested what the caller unit testing sometimes we also call this basis coding and unit testing be got things once but faces will work the mall want bill though full-fledged testing facing you're the bestest medical the cold and they do a complete their own destiny every morning with the independent panel investigating Madhu Kumar dual is November untested and finally they and their system is destined perceive it that the system is working in lane bid that requirements which has been and analyze understood and analyzed from the claims case so subse- quently after the testing the software is delivered with the clines and if required customer also that that acceptance testing *** law says this may in this life cycle based on this analysis based they sometime in January Danny second week then be keep on moving let's assume this is that one year project done by summit middle of December let him just before Mike be delivered the software to the client sold january february 9 p.m. be to requirements probably about much a blog painting design up the gun 9 p.m. holding and then testing and believe in the custom the time possible this in this traditional lifestyle what about Monday something like their wake up number one it is very logical told fine like that requirements and then water design and then board according and then we're guessing pretty logical sequence so bland everything up front then do after the plan I check for that everything goes after the plan and then keep on moving and finally apartment nobody like me has dicho 0 well low %uh %uh %uh ok on ok
