198 Part II: Planning Your Software Project developers hourly costs. You have to worry only about adhering to your project budget. Someone (the customer or project stakeholder) is paying for the developers time, or their salaries are incorporated into the cost of doing business. You need to understand what approach your project should follow when it comes to accounting and billing for your project team members time. Planning for Contingencies Estimates are usually based on idealized concepts of how things will go, while the actual project is full of conditions, risks, and (if you re smart) contingency plans. Plan on dealing with known unknowns. A known unknown is any event that is governed by Murphy s Law. You know there will be problems; you just don t know exactly what those problems will be or when they ll crop up. If you don t accommodate for these snafus up front when you create your budget, things can go bad. Unfortunately, some problems may be unavoidable, but they can still devastate a budget: Errors and omissions in the product scope mean that the developers take longer than expected once they figure out what they ve missed. Errors and omissions in the project work mean that tasks need to be performed that were never planned for. Miscommunications of all kinds can cause work to be undone and require reworking. Failure in user acceptability testing can mean you go back to the drawing board. Failure in quality control may mean that you have to recode a bunch of stuff. A hard drive crashes during a routine backup, and some development work needs to be done. (We know you would never forget to back up your work!) Poor requirements gathering means that your developers are working without all the necessary information. Project management errors mean that you spin your wheels a bit (hey, you ll get better with time). What you need is a contingency reserve. A contingency reserve, sometimes called a contingency allowance, is hidden treasure, a set amount of funds that the project manager may use to respond to known unknowns throughout the project.
