项目管理心得体会

项目管理心得体会  经过二郎山项目、鹧鸪山项目和水界等项目的项目管理工作实践,对项目管理的各方面事务感触颇深。

在此,我将这多年的心得体会梳理,抛砖引玉,希望各位同行及领导多多斧正。

  一. 管理时间就是管理自己,高效利用时间  每个人的工作课题存在差异,每个人的思想境界各有不同。

但是上帝却很公平的给了每个人一天24小时的时间,因此我们提出管理时间,是每个人都可以做到的事情。

每天把24小时规划好,也就管理好了自己。

平时大家会说时间不够,事情做不过来,我建议大家把时间拿出来分析一下,根据工作性质合理安排时间。

对于项目管理,事情多,工作琐碎.,这样我就养成了每天入睡前回顾一天工作的习惯,并对第二天的工作进行安排。

在安排工作上要求本部门各级员工把握一个主次分明,轻重缓急合理的原则。

这样每天当一到工作岗位上就能很快的进入工作状态,而员工的工作也各级抓好,紧张工作。

这样就很好的把握和做到--工作时效。

  二. 分清各项工作的轻重缓急  轻重缓急对于每个人来说都很重要,这就要求思路活跃,把火烧眉头的事情先处理掉,然后再去做日常工作。

就好比用户要一个深层次的技术交流,要求特别着急,这时你就需要安排资深的人员进行相关的支持,电话中能够完整的提供就现场进行,若是需面对面的进行,那好,用户的需要就是一切.总之轻重缓急具有非常的灵活性、时间性、场合性要视具体情况而当机立断。

做好了也是减少客户抱怨的有效方法。

  三. 不断规范和调整制度,没有规矩不成方圆  谈到管理,就一定要从规范入手。

规范是我们日常工作的行为准则,是企业生存、运作、发展、壮大的标尺和纲要。

它的实施者既是所有领导,又是全体员工。

只是各个岗位所规范的内容不同罢了。

万事开头难,难就难在你走出的第一步,第一步迈出去了,第二、三步就没有问题了。

正如我们日常工作,你没有第一稿资料,就没有后续的所有工作内容。

你最近没有向职能部门提交××问题,就没有人来问你这个或哪个问题是如何如何的,等大家都有反映了这件事情,就有人开始琢磨怎么样来规范这项工作,让大家都按这个规定来做。

以后大家就在这个基础上第二步、第三步的完善工作,把工作做得更好

任何事情都是一样的道理,只要你想做,你就会去规范这件事情,规范也就使每个人有了行为的准则。

  四. 提高会议效率,事前告诉大家会议的内容  工作中的很多问题都是在会议中解决的。

会议使我们对问题有了更多、更好的解决方案。

我们平常碰到的会议也比较多,大大小小、各式各样的都有,那么如何提高会议的效率就成为大家关注的事情。

如果我们在会议之前把要开会的事项告诉所有人,让大家都有准备,开会的时候就可以切入主题,谈每个人的思路,这样可以缩短一些时间。

往往在会议上大家谈着谈着就会跑题,这时候就需要会议的主持人能够引导大家的思路往一个方向;再有就是会议结束前主持人或主管人员一定要重述这次会议的几项内容和解决措施,这样大家才会感觉到会议的重要性。

  五. 统计数据,针对数据进行分析,分析结果加以应用,最后不忘评估、验证成果。

  统计数据简单的说就是一个工作量化。

是总结工作最直接、最明了的方法之一。

统计对于各块的工作都很重要,没有数据的分析,我们不知道努力的方向,至少说轻重缓急把握不好,有了数据就可以比较,知道目前面临最大的缺陷在哪里,针对弱点加以改进。

对于基层的管理人员来说数据的统计可以通过公司相关部门获得,得到的数据分析后一定要应用,只作分析不加以应用等于白搭,反而增加了工作量。

有的会说,我应用了但效果不大,问题就是应用后,有没有跟踪验证,我们对分析出来的数据没有应用,没有验证,怎么会知道我们的分析是对的呢

因此分析-应用-验证,三者一个都不能少。

  六. 愿景引来注意、尊重加深信心、沟通加强意义、立场导致信任  1)愿景--每次开会公司都会给我们描绘一下愿景,公司现在…… 即将……将来是…… 对于这些传到耳朵里的信息,员工们总是格外的在意,有的甚至在聆听笔记,这是不知不觉的愿景激励。

因为这些都与公司的每一分子的切身利益直接相关,不管愿景好与坏大家都会关注,我们跟同事开会的时候也不要忘记强调三年规划。

  2)尊重--同事之间相互尊重,可以加深合作,同时也会得到其他人的尊重,做起事情也会格外的舒坦。

工作之余都谈到沟通很关键,企业领导鼓励下属发言,但自己却不太发言也不太敢发言,所以最后的结果常常就是大家都不发言,最后就变成你看着我、我看着你,然后领导看着现场所有人,脸上一副「说话呀

」的样子。

这种状况就似乎是如果有一个人把话说出来之后他马上就会被企业宣判死刑一样,然后紧接着就被淘汰出局似的,所以大家对于自己想说的话都往肚子里吞,戒慎恐惧,一副「不要问我,我什么都不知道

」、「请你不要找我麻烦

」、「该死

怎么这么准,刚好问到我了

」的样子,所以只要你一鼓励他们把话说出来,大多数的时候,你很难获得到他们的回应,如果现场里有一、两个人敢勇于表达自己的意见,就已经算是不错的状况了。

  3)沟通--「说出来」是沟通最基本的原则,如果连话都不愿意说出来,沟通肯定不会有任何的进展。

如果在一个团队里,每一个人都必须要透过猜测才能够了解他人的想法,这将会是一件很累人的事,而如果你是待在这样团队里的一员,我相信每一天陪着你的一定是强烈的无力感。

只要打破不说话的几个因素:面子问题、怕担责任、中庸、以为别人知道。

主管或领导立场要坚定明确,我们平常说这个人没有立场,只要用户一投诉,主管就同意了;销售或市场一说,我们就得去做等等,这样同事会感觉到这个领导没有立场,别人怎么说就怎么做,以后有问题,他们也不会再问你,对你逐渐失去信任,因此主管人员一定要有立场,在立场发生变化的时候要和同事做好沟通。

  七. 定目标,严格执行、考核、监督  一件事情的好与坏如何去评价,首先要看所定目标定的合理性。

合适的目标对每个人、对企业都有好处,员工不会有太大的压力,安心努力的工作;企业每年都会稳步的积累和发展。

定目标对我们每个人说就再简单不过了,人的一生中不知道给自己定了多少目标,但真正努力去完成的又占了多大比例

目标就要靠人来执行,执行过程中就有各种各样的评价,严格的说就是考核和监督。

日常员工们努力的工作,都每个月底公司收集数据进行评估和考核,监督到年底每个是否能完成年初订立的目标。

  八. 人不要会什么,关键在于你会学什么  在学校不管你学习什么专业,80%的学生找不到和自己本专业相同的工作,多数都是改行,有的从事本专业临近的工种,有的甚至与本专业搭不上边。

从事本专业的人未必就有好的成就,从事非专业的人也有很多人打出一片天空。

因此人不要会什么,关键在于你会学什么。

  九. 培养人才资产:选、养、育、用、留。

  关键在于留,留有3个因素:能力、价值观、人生志趣;能力的体现就是知识内涵,价值观主要表现在技能和态度。

知识又分为:内隐知识和外显知识(内隐知识:平常看不到学不到的,要靠个人的感悟和积累;外显知识:看得到,学得到的东西)。

平常总是要经过选拔招聘到一个适合企业的人员,进入公司后像小树苗一样培育,初长成就要考虑如何使用,经历这一系列的洗礼,人就有一定的想法,因此如何留住人才也是公司要积极考虑的事情,特别是在资源不足的情况下留住人才就更难能可贵。

  十. 成绩好的时候要考虑如何提高团队的建设  随着其他公司技术能力逐步的提高,我意识到了靠个人的力量是不行的,要靠一个团队。

平时一个人忙里忙外不亦乐乎还不见的有效果,如何培养一支可以打胜仗的团队呢,首先要了解团队中的每个成员,发挥他们的优势,挖掘潜能,根据每个人的个性不同选用不同的岗位,每个人在团队中都发挥作用,管理人员就成功了一半,团队也就有竞争力了……

如何git clone别人仓库的代码

直奔主题,在Eclipse中使用git clone别人(比如网上的公开课)分享在Github上的代码:1.在eclipse中安装git:我使用的是ADT Bundle 的 eclipse,其中自带了git工具,如果使用的eclipse没有git工具可以打开eclipse 的Help>Install New Software.打开如图:在Name中随便填一个名字,Location填写 点击OK,回到图中背后的窗口中,勾选Name下的两个勾,记得把最下面Contact all update sites during install to find required software去掉(如果你网速很好的话可以不用去掉),OK,Next>Next,接受协议,然后点击安装。

安装完成如果有提示重启则重启,安装完毕。

2.从eclipse的git 克隆别人分享的代码:在Package Explorer空白处右击,选择Import>Git>Projects from Git,Next,选择URI(如果已经有本地的仓库久选local),打开如图:输入URI: 。

由于是clone别人的代码,所以不需要填写User和Password,直接Next,选择保存路径,Next完成clone。

在你的Package就有了该项目了。

接下来就可以自由的修改了。

(修改的当然是在你自己的机器上的代码啦)。

3.把自己的代码保存到Github上。

首先你要有自己的Github账号。

既然要把自己的代码保存到Github,那么前提就是你有自己的本地代码了,要把本地代码push到Github先要在本地有一个仓库(repository),所以首先在本地创建一个git repository:随便创建一个java 工程,在工程名上右击,选择Team>share project,打开如图,保持勾被选的状态(在本地创建git repository),点击finish。

发现项目图标改变了,说明创建本地仓库成功。

右击项目>Team>Remote>Push...打开对话框,如图,选择Custom URI(第一次配置选,以后直接在Configured remote repository选),填写上一篇文章申请Github账号中申请的URL,用户名和密码,点击next开始上传到Github,完成后可以去Github主页查看你的代码

到此,我们就可以使用eclipse中git工具clone别人分享的代码和上传自己的代码到Github上了。

A translation of the understanding of the economic 5000 words, on one side to understand the economic and trade at the same time, while browsing kingdomOutside of the trade, and the stock market trading quotas and other aspects of learning. I know the most influence is preliminaryChinese and English translation order should pay attention to in english-chinese translation should pay attention to the order of subject-predicate Penn, sometimes need before the objectBuy, buy, the subject after attributive object, and the measure to reduce the amount of add, word, should combine the context ` ` ` ` `Through the translation of the result I conclude when in translation should be paid attention to in the translation of the time want to pay attention to SiXin, namely, careful, care, enthusiastic attention. To have a zeal is the translation as a boring translation don't of translation, so have certain interest will be easier. To carefully, and in the translation of the time want to pay attention to add and reduce the measure, and point to, and pronouns consult the dictionary. Care, namely a not know much scrutiny, and every three, repeatedly pushed into thinking, of knowledge. Pay attention, and that is in daily life in the life of the attention of the English vocabulary, oral English, or to read the vocabulary of thinking and expand their vocabulary. At the same time, in the translation should also pay attention to several skills. 1 when you translation longer sentence word as far as possible, and word order to shorten the adjusted for Chinese habit in English is easy to appear clause set of clause the long sentences, the sentence read itself is hard to understand, if the translation or black changes, the translation of the time is read mouthful. I'm here for example it, 2 the vocabulary of diversity and one word that I also be opposite sex have a deep of it, because I personally word is enough, translation of the time can't live without powerword and baidu. In the translation of the time avoid to refer to some of the dictionary. But on the interpretation of the dictionary to provide there is no way to cover the Chinese words of, say, a word dictionary may only provide a very common explanation, use is the most common form of Chinese vocabulary. But if you mean in t translation, may also enter the erroneous zone. Making a word, making the marginal limit accrual, making the total gross income, making the tax officer for personnel market, such as a word again, used as a noun meaning for the market, but used as a verb and now points when word should be translated as marketing or sales. So when translation must diligent check dictionary, especially professional, and may refer to the dictionary online translation. At the same time, business and trade the use of words according to the occasion, there are formal and informal words of points, mainly used for formal formal legal documents, and in economic and trade informal words are used for news and talks draft, etc. For example: cancel a word on formal occasions will use in Liquidation and in informal situations it is cancel; End is a word on formal occasions termination and is in informal occasion it is end. Often people talk about all the style of the translation, I think t kind of words is the diversity of translation best reflects the style. In translation, should to be always put to feel the novel style of writing, so as to better think should with what kind of Chinese vocabulary to express, and at the right time, can use some allusions and idioms, the light will be many. 3 understanding and proper added on the whole, Chinese environmental protection than English, translated Chinese occupy storage space is general than English small. But some time with just a few words in English, or a prefix, translation into Chinese will explain half a day, and all can not have English that effect. This is the original sentence proper added. 4 translation accuracy. This kind of the article to the accuracy have very high request, even small technical errors, also can cause and original intention had the very big disparity, economic, trade translation of the requirements of the accuracy is high. Such as: lending may literally if the translation is commercial loan, and in the commercial habits is for shall be used for regular loan, also, is also important is not the business spending and should be translated as regular expenditure, similar examples are supporting the reform of supporting a counterpart counterpart funds supervision regulation of the financial firms in the translation of 5, according to sex.There are many economic and trade articles in the fixed appellation can't change, or easy to destroy people get used to the understanding, and even cause serious differences. If Shanghai Hong-such as one Corporation () cannot be translated into Hong Kong and Shanghai Banking company, and shall, in accordance with the habits into bank, I should not be on my account , and capital should be translated into capital project .给力啊
