Project estimates<\/p>\n

Project estimation is one of the key factors that determine project success or failure but very few people know how to do it correctly or put some efforts into it. Many software managers told me that they do NOT estimate their projects because things will change anyway. Other told me that even if they do estimate, their customers may not agree with their estimation or change their minds so why waste time. This is a major mistake because in that case, project managers allow customers to dictate the schedule and budget of the project to them. How do you like to work in a project when you know that the schedule is unreasonable and you do not have enough people to do the job? How do you like to work in a project that you know that it will fail to meet schedule and functionality? How do you like to work in a project that you know that it will be late even you have to work very hard to meet the schedule? I have seen that when a project is late with higher costs and less functionality, many project managers would blame on bad requirements, or blaming customers changing their minds often. Very few managers would admit that they do not know how to estimate on how long will it take to complete the project (Schedule), how many people will the project need to do the job (Resources), and how much does it cost (Budget).<\/p>\n

My view is estimates will allow project manager to identify risks that may prevent the project from achieve its goal. Estimates will NOT produce better requirements. It will NOT stop customers from changing their minds. It may NOT change the schedule. It may NOT give you more people or budget but it WILL produce an accurate evaluation of the risks involved of the project. Estimate WILL give you the possibility on whether the project would be succeeded or not. By having these estimates (Schedule, resource, budget), project managers can set expectations CORRECTLY with customers so a RESONABLE agreement can be achieved. A good project manager should know how to negotiate with customer on the critical risks of certain situations.<\/p>\n

Let me give you an example: A customer requires a project to have 10 functions to be completed in 4 months with a budget for 5 software developers. Your estimate comes up with 6 months to complete the project with the given functionality and resources. You can ask the customer whether it is possible to extend the schedule from 4 months to 6 months. If the answer is NO then you can let the customer know that with the current budget for 5 people, you may NOT be able to do that within the 4 months required but if customer can increase budget from 5 to 7 software people, then you can meet the required date. If the answer is NO then your last request would be you will complete the project with 5 people in 4 months but only implement 6 functions instead of 10 functions. Basically, there are three factors (Schedule, resource and function) or a combination of those three factors that you can negotiate. It is very likely that you will end up with 6 people, 5 months and 8 functions after intensive negotiation. At least it is better than what you are given in the first place.<\/p>\n

Negotiation is a critical skill of good project manager but it is NOT taught in school. Of course, before you learn how to negotiate, you must know how to estimate because without estimation, you can not come up with a negotiation strategy. Estimation should be viewed as a critical part to mitigate many risks that might impact a project. When estimating is recognized for its value, customer and senior management will be more likely to accept that by require project managers to have this skill.<\/p>\n

The SEI Capability Maturity Model (CMMI) suggests that an organization\u2019s maturity is based upon a well defined and effectively executed process. A clear statement of estimating policy backed by a well defined estimating process is a major factor in achieving a CMMI Level 3 rating. (If your organization is appraised at higher maturity rating but your estimating process is NOT well in place then you may want to ask the CMMI appraisal person whether he is serious about his business or just \u201cCheat\u201d an appraisal for the money). Accurate estimating requires a lot of historical data and these data can only be collected if there is an acknowledgement by management that it is important factor in determining project success.<\/p>\n","protected":false},"excerpt":{"rendered":"
