PERT Charts, Gantt Charts, Risk Management and more — All software projects big or small need some degree of management. EXECUTIVE SUPPORT Lack of executive support is cited as one of the top reasons software projects fail. The highest‐ranking executive who supports your project is often known as an executive champion or an executive sponsor . Robust executive support ensures that…

documentation is good. You should do it. — Before you start coding, prepare some documents to clarify your thoughts and designs. DOCUMENT MANAGEMENT Software projects often have many documents. Some documents are “living” documents that change over time. As new things are discovered, the requirements may change. If the requirements change too easily, developers may not be able to finish…

intro — There are two ways of constructing a software design. One way is to make it so simple that there are obviously no deficiencies. The other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult. — C.A.R. Hoare [1] Requirements Gathering Start…

Intro to Customer Relationship Management Software — Background Believe it or not, there was a time before CRM Software. CRM stands for Customer Relationship Management Software. Back in the day you used to have to do these things yourself. Your sales manager might even manually track your results in a corporate mainframe. It was very unsophisticated back in…

Study how digital signals fade over the air and why — The LTE module has a trace-based fading model. [2] What is a Fading Model? In wireless communications, fading is variation of the attenuation of a signal with various variables. These variables include time, geographical position, and radio frequency. Fading is often modeled as a random process. A fading channel is a communication channel that experiences…

find the longest sequence of zeros in a binary representation of an integer — A binary gap within a positive integer N is any maximal sequence of consecutive zeros that is surrounded by ones at both ends in the binary representation of N. For example, number 9 has binary representation 1001 and contains a binary gap of length 2. The number 529 has binary…

a brief introduction with references — An overview of the LTE-EPC simulation model is depicted in the figure below. What is EPC? Evolved Packet Core (EPC) is a framework for providing converged voice and data on a 4G Long-Term Evolution (LTE) network. 2G and 3G network architectures process and switch voice and data through two separate sub-domains: circuit-switched (CS)…

A quick review — You would have come across a term called space complexity when you deal with time complexity. Similar to time complexity, space-complexity is also an important parameter to determine the efficiency of an algorithm/program. In this article, let’s discuss how to calculate space complexity in detail. [2] Space Complexity The space complexity of…
