17 Signs You Work With cmdplay
"The single most important task of a project: setting realistic expectations. Unrealistic expectations based on inaccurate estimates are the single largest cause of software failure."- Futrell, Shafer
Introduction
With global and competitive market, it is very important to launch a product or service in the market on time, ahead of competitors. Definitely, timely launch depends on on-time-completion of the product development projects. Project planning has lots of challenges to overcome in order to finish the project on time - right from schedule predictability, envisioning future/possible risks and coming up with mitigation plans.
This article talks about some of the challenges, often faced in the Software Product Development industry that causes the schedule slippage.
Schedule slippage: Delay in the project completion from its initial estimated date of completion.
Each project plan will have a planned completion date (NRA, RA), and a bounding box or upper limit in schedule. Nowadays, it is a common practice to have three dates associated with any project plan:
Root Causes
As we always plan for a project to get over before RA date, seldom is the case it happens as expected. There are multiples reasons for schedule slippage, right from improper planning, lack of resources to unplanned requirements and rework that eat away vital time off the planned schedule.
A typical project development process - Each project will have a team (development, testing and other functions) that will work cmdplay login through a process (requirement analysis, schedule estimation, design, implementation and testing) to deliver a product to the customer/end user. Each entity that participate in the project - directly or indirectly affect the schedule.
From the development process, we can identify the items that can cause delay in the execution of the project - for example, misinterpreted or unclear requirement adds up to completion time, unavailability of development tools or resources can prolong the project duration. Various processes like schedule estimation, detailed design and product development if not executed skillfully, may significantly blow up the project cycle.
For better understanding all these possible causes that may result in schedule slippage are categorized .
Let's have a detailed look at the root causes of schedule slippage category wise.
1) Schedule Estimation: "The key is not to prioritize what's on your schedule, but to schedule your priorities." - Stephen Covey
For a project to be executed on time, it is very important to have it planned very well. Any mistake in project schedule estimation reflects as delay in the project completion from its deadline. There are several factors that contribute to improper schedule estimation:
On time delivery is the challenge software development companies are facing globally. To have a complete control over estimated schedule, it is very important to identify the elements in the development cycle that cause schedule slippage. This article uncovers and explains the root causes of delay in programs using examples from real world. Having an insight to the root causes will help the program managers to make good decisions to avoid future schedule slippage.
Firstly, this is going to be a bit lengthy read about the 3 run commands which will make your PC run faster, but it will prove very useful so don't let the length overwhelm you.
Well, through all my experience with PC troubleshooting, I have but drawn an impenetrable conclusion that:
No matter how generously you spend on antivirus/antimalware packages, they only guarantee protection to a certain degree and against a certain set of threats. However, the biggest threat to a personal computer always remains undiscovered i.e: mismanagement or lack of proper management which is required on a regular basis. And unfortunately, if you fail to take care of that, then I am afraid your computer is going to malfunction sooner or later!
Management extends from just installing a protection software to sorting your personal files and configuring what applications and services run at your computer's start up. This article is only going to cover a few substantial run commands in detail - which you can execute by pressing the 'windows key and r' simultaneously - that are going to greatly help you manage the afore-mentioned tasks at ease of access.
Run command number 1: Add or Remove Programs:
- Press 'windows' + 'r'
- Type in the run command: appwiz.cpl
- Press enter to execute
To benefit from this command, firstly, you need to take notice of the shortcuts on your desktop and scout for unwanted software - the ones you never or no longer use - that is there. Finalize that it is of no use to you, follow the instructions to the above mentioned command, and enter the control panels' 'Add Or Remove Programs' menu.
Keep scrolling down on this window until you find and remove all the unwanted software from your computer. Removing unwanted software not only makes your computer look cleaner, it also recovers some RAM that was once dedicated to that certain software hence, quickens up the computer's processing pace a bit.
Run command number 2: Direct X Diagnostic tool and I/O Configuration:
- Press 'windows' + 'r'
- Type in the run command: dxdiag
- Press enter to execute
Whenever you're trying to remember your computer's hardware specifications, guessing your computer's RAM trying to find out your Mother Board's, Graphix Adapter's or Operating System's model name and number, I need you to know that it's really unnecessary when the solution is right at the tip of your very fingers.
The 'Direct X Diagnostic Tool' is one of the most useful run commands since, it displays a huge amount of information about your computer on a single window, isn't hard to execute and acquires a negligible amount of RAM!
Run command number 3:
- Press 'windows' + 'r'
- Type in the run command: msconfig
- Press enter to execute
By far the most important command as far as personal computer management is concerned!
This command pops open the 'System Configuration Utility' - in a new window - which enables you to control what services (background processes) keep running on your computer after the OS is loaded and most importantly, what programs run on your computer at start up.
By properly managing only these two things, you can optimize your computer's performance to great lengths. In the Utility window, under 'Services' tab, you will find background processes either stopped or running such as: Auto Updates, Windows Installer, Plug & Play etc. Most of them, I wouldn't recommend messing around with but there are a few obviously useless ones in there that you wont miss out if you look closely. Stop them from running immediately!
In the 'Utility' window under 'Startup' tab, you will find listed the software that run on start up. If you find them of no use and observe that they are slowing your computer's start up down, stop them from running on start up instantly and restart your computer to apply changes. You can always run these programs once your computer has properly started.
This had indeed been quite an awfully detailed one. Well, hope it helps you clean up.
Cheers.
