The appeal of Agile or lightweight development methods has grown steadily in the software development community. Having spent a number of years investigating strategic planning approaches, I've recently been thinking about whether Agile principles can be--and should be--applied to strategic planning. This blog post examines the applicability of Agile principles to strategic planning.
Our SEI blog has included thoughtful discussions about sustaining software, such as the two-part post "The Growing Importance of Sustaining Software for the DoD." Software sustainment is growing in importance as the lifetimes of hardware systems greatly exceed the normal lifetime of software systems they are partnered with, as well as when system functionality increasingly depends on software elements. This blog post--the first in a multi-part series--provides specific examples of the importance of software sustainment in the Department of Defense (DoD), where software upgrade cycles need to refresh capabilities every 18 to 24 months on weapon systems that have been out of production for many years, but are expected to maintain defense capability for decades.
The SEI has been actively engaged in defining and studying high maturity software engineering practices for several years. Levels 4 and 5 of the CMMI (Capability Maturity Model Integration) are considered high maturity and are predominantly characterized by quantitative improvement. This blog posting briefly discusses high maturity and highlights several recent works in the area of high maturity measurement and analysis, motivated in part by a recent comment on a Jan. 30 postasking about the latest research in this area. I've also included links where the published research can be accessed on the SEI website.
We use the SEI Blog to inform you about the latest work at the SEI, so this week I'm summarizing some video presentations recently posted to the SEI website from the SEI Technologies Forum. This virtual event held in late 2011 brought together participants from more than 50 countries to engage with SEI researchers on a sample of our latest work, including cloud computing, insider threat, Agile development, software architecture, security, measurement, process improvement, and acquisition dynamics. This post includes a description of all the video presentations from the first event, along with links where you can view the full presentations on the SEI website.
Over the past several years, the SEI has explored the use of Agile methods in DoD environments, focusing on both if and when they are suitable and how to use them most effectively when they are suitable. Our research has approached the topic of Agile methods both from an acquisition and a technical perspective. Stephany Bellomo described some of our experiences in previous blog posts What is Agile? and Building a Foundation for Agile. This post summarizes a project the SEI has undertaken to review and study Agile approaches, with the goal of developing guidance for their effective application in DoD environments.
Managing technical debt, which refers to the rework and degraded quality resulting from overly hasty delivery of software capabilities to users, is an increasingly critical aspect of producing cost-effective, timely, and high-quality software products. A delicate balance is needed between the desire to release new software capabilities rapidly to satisfy users and the desire to practice sound software engineering that reduces rework.
In our work with acquisition programs, we've often observed a major problem: requirements specifications that are incomplete, with many functional requirements missing. Whereas requirements specifications typically specify normal system behavior, they are often woefully incomplete when it comes to off-nominal behavior, which deals with abnormal events and situations the system must detect and how the system must react when it detects that these events have occurred or situations exist. Thus, although requirements typically specify how the system must behave under normal conditions, they often do not adequately specify how the system must behave if it cannot or should not behave as normally expected. This blog post examines requirements engineering for off-nominal behavior.
In the first post in this two-part series, we covered five unique challenges that impact insider threat programs and hub analysts. The challenges included lack of adequate training, competing interests, acquiring data, analyzing data, and handling false positives.
As you read the new challenges introduced in this post, ask yourself the same questions: 1) How many of these challenges are ones you are facing today? 2) Are there challenges in this list that lead to an "aha" moment? 3) Are there challenges you are facing that did not make the list? 4) Do you need assistance with combating any of these challenges?
